Duquesre Light Company1991 Anaual Radiological Environmental Report
EXECUTIVE SUMMARY
This report describes the Radiological Environmental Momtoring Program conductedduring 1991 in the vicinity of the Beaver Valley Power Station Units 1 and 2. TheRadiological Environmental Program consists of off-site monitoring of water, air,river sediments, soils, food pathway samples, and radiation levels in the vicimty ofthe site. This report discusses the results of this monitoring during 1991.
Duquesne Light Company operates the Beaver Valley Power Station Umts 1 and 2pressurized water reactors as part of the Central Area Power Coordination Group.
The Beaver Valley Power Station Unit 1 operated throughout 1991 except during theEighth Refueling Outage April 12 through July 20, 1991, and dining threemaintenance outages January 17 through January 31, Septerr ber iS throughSeptember 25, and October 22 through November 28, 1991. The highest average l
daily output generated during the year was 836 megawatts net in Decembr- 991, |and the total gross eiectrical generation during the year was 3.921.000 !megawatt-hours. |
Beaver Valley Power Station Unit 2 operated throughout the year except for a brief j
outage, November 26 through November 28,1991. The highest average daily output I
generated during the year was 823 megawatts net in February,1991, and the totalgross electrical generation during the year was 7,099,800 megawatt hours.
in 1991, samples were taken from over 60 sites around Beaver Valley Power Stationthat ' included the aquatic, atmospheric and terrestrial environments. More than3,000 analyses were performed on these samples.
During the year, the radioactive releases from BVPS Units 1 and 2 did not exceed jthe Limiting Conditions for Operation identified m the Beaver Valley Power Station
IOperating License Technical Specifications for Units 1 and 2. Based upon theestimated dose to individuals from the natural background radiation exposure, theincremental increase in total body dose to the 50-mile population (4 million people),from the operation of Beaver Valley Power Station - Unit No.1 and No. 2, is less |than 0.0001% of the annual background, See Section V.! for specific details. TheNational Academy of Sciences 1990 BEIR Report shows that the typical dose to anindividual from background (natural radiation exposure includmg radon) is 296 mremper year.
The environmental monitoring program outlined in the Beaver Valley Power StationUnits 1 and 2 Technical Specifications was followed throughout 1991 The results foreach media are contained in Section V of this report, Examination of effluents andenvironmental media show that it'e Beaver Valiey Power Station Units 1 and 2operations have not adversely affected the surrounding environment.

Section 1. INTRODUCTION
.
A. Scope and Objectives of the ProgramzThe environmental p cgram consists of environmental momtoring for radioactivity in -the vicinity of the Beaver Valley Power Station. Environmental sampiing andanalyses included air. water, milk, soil, vegetation river sediments, fish, andambient radiation levels in areas surroundmg'the site. The results of these mediaare assessed to determine impacts of the plant operation on the environment. The
'Annual--Radiological Environmental Report for the Beaver Valley Power Stationsummarizes the radiological environmental program conducted by the DuquesneLight Company in 1991.
B. Description of the Beaver Valley SiteThe Beaver Valley Power Station is located on the south bank of the Ohio River mthe Borough of Shippingport, Beaver County, Penns,:vania on a 501 acre tract of
- land, Figure 11 is a view of the Beaver Valley Power Stahon. The site isapproximately one mile from Midland, Pennsylvania; 5 miles from East Liverpool._ Ohio; and 25 miles from Pittsburgh, Pennsylvania. Figure 1-2 shows the sitelocation in relation to the principal population centers. Population density in theimmediate vicinity of the site is relatively low. The population within a 5 mile radius
- of the plant is approximately 18,000 and the only area wit hin the radius ofconcentrated papulation is the Borough of Mir' 'd, Pennsylvania, with a populationof approximately 3,300.
The site ties in a valley along the Ohio River. It extends from the river (elevation665 feet above sea level) to a ridge along the border south of the Beaver ValleyPower Station at an elevation of 1.160 feet, Diant ground level is approximately 735feet above sea level
! The Beaver Valley Power Station is on the Ohio River at river mite 34.8. at a locationon the New Cumberland Pool that is 3.3 river miles riownstream from MontgomeryLock and Dam, and 19.4 miles upstream from New Cumberland Lock and Dam. ThePenns'ylvania-Ohio-West Virginia border is located 5.2 river miles downstream f.omthe site. The river flow is regulated by a series of dams and reservoirs on the"
Beaver, Allegheny. Monongahela and Ohio Rivers and their tributaries. Flow rangesfrom a minimum of approximately 5000 cubic feet per second (CFS) to a maximurnof approximately 100,000 CFS. The mean annual flow is approximately 25.000 CFS.
; -
Water temperature of the Ohio River varies from 32 F. to 84 F, the minimumtemperatures occur in January and/or February and maximum temperatures in Julyand August. Water quality in the Ohio River at the site location is affected primarilyby the water quality of the Allegheny, Monongahela, and Beaver rivers.
The climate of the area may be classified as humid continental. Annualprecipitation is approximately 36 inches, typical yearly temperatures vary fromapproximately - 3'F to 95 F with an annual average temperature of 52.3 F. The-predominant wind direction is typically from the southwest in summer and from thenorthwest in winter.

Section 2. RESULTS AND CONCLUSIONS=
Plant operations at the Beaver Valley Power Station had no adverse effects on theenvironment as a result of activity at the station during 1991;
The Beaver Valley Power Station Umt 1 operated throu0 out 1991, except during theh
Eighth Refueling Outage April 12 through July 20, 1991, and three maintenanceoutages January 17-31. September 18-25, and October 22 - November 28,1991. Umt,
2 operated throughout the year except for a brief outage. November 26-28, 1991.During the year, the radioactive releases were below the hmits of 10 CFR Part 50,Appendix 1. The releases at Beaver Valley Power Station Umts 1 and 2 did not
exceed the limiting conditions identified in the Beaver Valley Power Station Omts 1and 2 Operating License Technical Specificahons.
The environmental piogram for 1991 was the same as in 1990 except for severalchanges in dairy locations which were revised as required by the Beaver ValleyTechnical Specifications. (Refer to Table 5-1 for the 1991 Radiological MonitoringProgram Outline).
The Beaver Valley Power Station Technicat Specifications require s. apling of three(3) dairies which have the highest calculated milk pathway potentia. and one largelocal dairy. The three dairies are determined from calculations cased on themeteorological data and the latest milch animat survey. However, these dairies arefrequently small, consisting of as few as one cow or goat. The availabihty of m:lkfrom single cow dairies 'and revisions due to updated calculations and surveysnorrnally result in sampling of several additional dairies during the year in differentsampling periods,
The Environmental Monitoring Program also includes two larger dairies in order toprovide continuity in the sampling / analyses program and a control location.Sarnples from each of these. dairies are obtained in addition to the four dairiesrequired -by the Environmental Technical Specifications. The collection periodsassociated with each of the locations are provided in the detailed summary of themilk monitoring program of this report (Section 5-E).
Activity detected was attributable to naturally occurring radionuclides, BVPSeffluents, previous nuclear weapons tests, medical procedures or to the normalstatistical fluctuation for activities near the lower limit of detection (LLD). Thepositive results attributable to the Beaver Valley Power Station were consistent withstation data of authorized radioactive discharges and were within limits permitted bythe NRC license.
The results and conclusions for each media of the 1991 Radiolo@al Environnsna. Monitoring Program are contained in Sectir 7 5 of this report. A summary of the1991 operational environmental data is found . in Table 5-2 and a summar / off reoperational data (1974-1975) environmental data is found in Table 5-3.
Examination of effluenis from the Beaver Valley Power Station and environmentalmedia demonstrated compliance with regulations and Station TechnicalSpecifications.

Section 3, ENVIRONMENTAL MONITORING CONSIDERATIONS
.
A. Environmental Quality Control Programs,
The Quality Control (QC) Program used for the Beaver Valley Environmental )Radioactivity Monitoring Program consisted of seven (7) elements. It should benoted that the comparisons made v.ere at very low levels of radioactivity and |
consequently, the activities at these levels are difficult to measure. However, |
acceptable correlation was achievad in most instances as outhned in the |'
dHcussions and tables which follow.
1. TLD Monitoring (Duquesne Light Company (DLC) Contractor Laboratory and OCLaboratory)
.||Thirteen (13) TLDs from the Contractor Laboratory and OC Laboratory are
co-located, replaced quarterly and results compared. The average of the
contractor laboratory and the average of the quahty control laboratory agreewithin 7.9% of the mean of all results. This is well within the 7 cision oftypical TLD Systems. Summary data of the TLD Monitoring Frograrn isprovided in Table 3-1,
2. Spht Sample Program (DLC Contractor Laboratory - DLC QC Laboratory)
Samples of surf ace (river) water and drinking water were routinely split andanalyzed by the DLC Contractor Laboratory and the DLC QC Laboratory. inaddition, samples of other media, st.ch as milk, soil, sediment and feedcropwere also sp"t with the DLC QC Laboratory.
A summary of results of spht water sampias is provided in Table 3-2 andTable 3-3. In 1989 and 1990 disagreement in surface and drinking gross betawater ramples had been noted. Changes in laboratory procedures were madeand in 1.i91 seven of eight split gross beta's were in agreement and one wasclose to agreement. Six extra surface and drinking water samples were sphiand processed for gross beta. All meet agreement criteria. Summaries ofmilk, sediment and feed / food crop split samples is provided i1 Table 3.t andT1ble 3-5. Some variation may be expected due to small variations in
duplicate samples, variations in analytical procedures, and in calibration,
source type, etc.

-3L DLC QC Laboratory Program
Spiked samples prepared _by DLC QC Laboratory were routinely submitted to-~
the Contractor Laboratory for. analysis. Table 3-6 (water) and Table 3-7 (milk) .provide data from this portion of the QC Program.
4 Comparisons of Similar - Samples (DLC Contractor Laboratory -' DLC QC-
4
Laboratory),
Duplicate air particulate - and charcoal - fillers - (radiciodine) samples were,
collec%d at Location =30 and compared during the year on a weekly basis. ;i- . Comparison of particulate and charcoal samples alternated from week to week.
Duplicate monthly air' particulate filters, composited from the weekly, air *
oarticulate fiiters, were analyzed 6 months out of the year for gamma activity.Duplicate' quarterly air- particulate filters, composited from the weekly ait'particulate filters, were analyzed for Sr-89 and St-90 activity for each quarter ofthe . year, Table 3-8, Table 3-9 and Table 3-10 provides data for this portion ofthe QC program.
5. Contractor and OC Laboratory - Internal _ QC Program ,
;
"The' Contractor and -QC Laboratory maintained their own QC Progr.am which -!
included participation in the Environmental Protection Agency - Environrnental '
Monitorin0 Safety Laboratory (EPA - EMSL) Interlaboratory Cross Check.
Program. This cross check program indicated that _the Contractor and QCLaboratory results were in' agreement with EPA EMSL. See Appendix I and ll.
:DLC: also audited the Contractor and QC Laboratory and determined -thatinternal. QC practices were in effect and that procedures ~ and laboratory
1- analytical techniques conformed to approved DLC procedures.
6. Speda! QC. Program (DLC Contractor Laboratory - Independent Laboratory -DLC QC Laboratory)
,~ Milk and water samples were prepared by an Indoendent Laboratory. Thisincluded-low level spiking of specified nuclides. - The prepared samples weresplit: three ways and analyzed. by the- DLC-QC ' Laboratory and Independent
~
; Laboratory as well as the Contractor Laboratory. A summary of results of thisportion - of the QC program 'is provided in Table 3-11. Contractornon-comparison with the Independent Laboratory for i+131 in water provided inTable 3-11 and Sr-89-90 in milk provided -in Table 3-12 is discussed in thefollowing paragraphs;

i|^
The contractor _ laboratory 1-131 in water results were noted to have a low bias_
compared; to the independent' and the QC laboratory for sample _ spikes~ produced by the independent laboratory. All laboratory work and calculations'.
for these 1-131 samples were verified by the contractor. This low bias had not ij- .been observed in the previous year and no known changes which could effect
results had been inade in the laboratories or procedures. Essentially the same_ procedure is _used by the contractor._for both milk and water samples and in .1991- all' milk samples for 1131 produced by the independent laboratory and - i
analyzed by the contractor met agreement criteria. Also in 1991, agreementwas obtained in spike samples produced by the QC laboratory for 1131 in water
| and milk with one exception where the contractor result was high rather thanp Llow. The most probable cause of the low bias in 1-131 results by the contractor' ,
is differences in the sample preservation of the independent laboratoryprepared spike compared to routine samples and/or QC laboratory preparedspikes. Such a bias would not effect routine sample results. In 1992 a differentvendor will supply the independent laboratory spike samples and the contractor .
has also re-issued (for other reasons) the analytical procedure for iodine in _,
,. water. Results of iodine in water spikes will be followed closely m 1992 to'
obtain resolution of any corfinued bias,
i The contractor laboratory obtained background results for Strantium 89 and 90_on;two spiked milk sant es (52-259 and 59-260) prepared by the independentl
l' laboratory. The. independent laboratory stated the split samples were'madefrom -or'e batch and that. no preservatives were used. Although the _ split
,
samples were not treated in the same manner as routine samples (bisulfiteaddition) no previous problems _had been observed. Gamma activities presentin the sample were comparable between laboratorie . Although the contractorlaboratory did 'not obtain comparison- for Sr 89-90 for the abcve samplesprovided by the independent laboratory, in the same time period comparisons,
[ were obtamed for Sr 89-90 in milk on samples provided by the QC laboratoryand also by. the EPA Interlaboratory Cross Check Program. Agreement wasobtained between the contractor and independent: laboratories for Sr-89-90 in
. milk on the last scheduled sample of the year (52-261) and also on a specially,
arranged extra sample (52 261-A). It remains unclear whetrar the discrepancy'
in Sr 89-90 results were due to the sample provided on the analysis' performed.In.the following year, a different vendor will supply _ the independent _ laboratory_ spike samples'and the.-contractor has also made a procedure revision. Thecomparison of Strontium 89-90 in milk will be followed closely in 1992.

D. Evaluation of the Quality Control (QC) Program DataThe spht and spiked sample program indicates that the Contractor and CCLaboratory are generally performing satisfactors|y m accordance with * Criteria forComparing Analytical Measurements from NRC Comphanc e Ufhce." In addition, anindependent taboratory is used to supplement the regular program. Compansonsbetween the mdependent, QC and Contrattor laboratories are generally acceptableand demonstrate a satisfactory performance by the DLC contractor All media werefound to be in agrnement in accordance with NRC criteria as hsted in InspechonGuidance 84750-03 dated 12/04/90 with the exception of those media m Table 3 2through Table 312 identified with an asterisk (*).
Based on all available QC data and the data from the Contractor and QCLaboratory's internal EPA Intertaboratory Cross Check Program, the EnvironmentalMonitoring Prograrn for 1991 is acceptable with respect to both accuracy andmeasurement.
C. Standard Requirernents and Limitations for Radiological and Other EffluentsThe Beaver Valley Power Station is governed by rules and regulations of theFederal Government and the Commonwealth of Pennsylvania, Ettluent releases arecontrolled to ensure that hmits set by Federal or Stato governments are notexceeded, in addition, self-imposed hmits have been established to further hmitdischarges to the environment.
Beaver Valley Power Station is subject to regulations which include the Code of- Federal Regulations 10 CFR (Energy).

A. Monitoring of Liquid Effluents
1. Descriptson of Liquid Effluents at tho Beaver Valley Power Station.
Most of the water required for the operation of the Beaver Valley station is takenfrom the Ohio River. and returned to the river, used for make ip to various p; antsystems, consumed by statien personnel, or discharged via a sanitary wastesystem. in addition, small amounts of well water and hquid effluents are
discharged to the Ohio River using discharge points shown m Figure 41.Figure 4-2 Figure 4-3. Figure 4-4 and Figure 4 5 are schematic diagrams ofliquid flow paths for the Beaver Valley Power Station.

2. Atmospheric Effluent Treatment and Sampling
.
. Beavet Valley Power Station (Umts 1 and 2)
Radioactive gases enter the gaseous waste disposal system from the degasifiervent chiller of the boron recovery system, and are directed to the gaseous wastecharcoal delay subsystem upstream of the overhead gas compressor where thegas is chilled to condense most of the water vapor. Gases from the degasibervent chillers contain primardy hydrogen and water vapor. A small amount ofnitrogen - and radioisotopes consisting of noble . gases, particulates andradiciodmos are also present in the eight continuous ventilation system
pathways.
The overhead gas compressor directs the radioactive gas stream to a gas surge ;
tank. Gas is periodically transferred from the Unit 1 or Unit 2 surge tank to oneof the three (3) decay tanks at Umt 1 or one of the seven (7) decay tanks at Umt
,
2. After the decay tanks are sampled and authoritation obtained for discharge. -;
the flow of the waste gast' from the decay tanks (2 sctm) is recorded and,
tapidly diluted with about 1000 scfm of air in order to dilute hydrogen andradioactive effluent concentration. The gases are then combmed with nitrogenpurge from the oxygen analyters, cahbration gas from the oxygen analyters, themain condenser air ejec|or exhaust, the containment vLcuum system exhaust,aerated vents of the vent and drain system, discharge of the overhead gascompressor and the purge from the multi sample point radiation mnnitor. Themixture is then fjltered through one of the gaseous waste disposal filters, each .
'
of which consists of a charcoal bed and a high efficiency filter. The filteredgases are then discharged by one of the gaseous waste disposal blowers to theatmosphere via the process vent on the top of the Unit 1 cooling tower. The
.
radioactivity levels of th'e stream are monitored continuously.
Should the radioactivity release concentration of the stream go at:ove theallawable setpoint, a signal from the radiation monitor will stop all flow from the
,
Unit 1 or Unit 2 decay tanks being discharged.'
,
During a shutdown period after the Unit 1 or Umt 2 containment has been,
sampled and the activity levels determined, purging may commente through theVentilation Vent located on top of the Auxiliary Building or the Supplementary |
'
Leak Collection and Releaso' System (SLCRS) Vent located on top of the Reactor 6
Containment BuHding or the Process Vent located on top of the Cooling Tower.
Areas in the Unit 1 Auxiliary Building (subject to radioactive contamination) are,
mc.mtored for radioactivity prior to entering the common Ventilation Vent. These,
individual radiation monitors aid in identifying any sources of contaminated air. I
!: The Ventilanon Vent is also monitored continuously by' several redundantchannels of the Radiation Monitoring System (RMS) and is sampled periodically. ;
Upon a high activity Plarm, automatic dampers divert the . system's exhaust air '
'' ~
stream through one _of the main filter banks in the Supplementary LeakCollection and Release System (SLCRS) and to the SLCRS Vent. ,

is samp?9d penodically for determination of radioactive material and is
monitored coot;nuously by other channels of the Digital Radiabon Monitcrmg .
System (DRM.5 ).
Each Unit 1 and Unit 2 futer bank consists of roughing filters, charcoal fdters.andc pleated p' ass liber type HEPA filters. The roughing hiters remove targo; particulates to prevent excessive pressure drop buildup on the charcoal and

3.. Results
|Beaver Valley Power Station
|
Gaseous effluents from the Beaver Valley Power Station were released in |':accordance with conditions noted in Section 3/4112 of the Technical
Specifications. No limits were exceeded. These values have been reported in |the Beaver Valley Power Stahon Semi Annual Radioactive Effluent Release !Reports for 1991. t
C. Solid Waste Disposal at the Beaver Valley Power Station
.
During Beaver Valley Power Station normal operations and periodic maintenance. ;
small quantities of sohd radioactive waste materials were generated such as'contaminated rags, paper, plastics, litters, spent non-exchange resms, and
misce!!aneous tools and equipment. These were disposed of as sohd radioactivewaste.
-The services of offsite vendors were used Ic se0regate. incinerate, andsuper compact the waste. . At the Beaver Valley Power Station, the compactabln i
wastes are segregated and the capabihty exists to cornpress the waste m SS gallondrums to minimize disposal volumes. The waste is sinpped for disposal at a
,
commercial radioactive material burial site licensed by the Nuclear Regulatory |'Cormnission (NRC) or a state under agreement with the NRC. No radioactive waste
rnaierial is buried at the Beaver Valley Power Station site. *
t
All containers used for packaging, transport, and disposal of radioactive materials -
met the reqmrements of the United States Department of Transportation (DOT) andthe Nuclear Regulatory Commission (NRC). Shipments offsite were made m
accordance with DOT and NRC reculations. Figure 4-8 depicts solid waste handling >
at the site.
'
At Beaver Valley Power Station approximately 6,155 cubic feet of radioactive solidwaste was' buried offsite in 1991. The forty-sin (46) shipments contained a totalactivity of 1080 curies.
,
' Industrial solid wastes were collected in portable bins, and removed in an approvedoffsite burial ground. No burning or burial of wastes was conducted at the BeaverValley Power Station site,

(a) Control sample station: These are locations which are presumed to be outside- Ie
the influence of plant effluents.
'(b) Typical LLD's for Gamtra Spectrometry are shown in Table- 5-4.1
(c) Particulate samples are not counted for 2: 4 hours after filter change. Perform- -|
gamma isotopic analyais on each sample when gross-beta is > 10 times the |yearly mean of control samples. !
],(d) ' Analysis composites are well mixed actual samples prepared of equal portions
'
from each shorter term samples from each location.
(e) Composite samples are collected at intervals not exceeding 2 hours.;
(f) Weekly milk carspie from Searight's Dairy is analyzed for I 131 only. 1
(g) Milk samples are collected b;-weekly when animals are in pasture and monthly |'
at other times, [ Assume Ap el October for grazing season (pesture); 1
--(h) ' The milk samples from Brunton's and Nicol's are collected once per month. j'
!
(i). The fish samples will~contain whatever species are available. If :the available-sample size permits; then the sample will be separated according so. species . i
and compositing -will provide one sample of each species, if the available sizeis too small to make separation by species practical, then edible parts of all-,
fish in the sample will be mixed to give one sample.
(j) Composite ~ samples' .are collected at - intervals not exceeding 2 hours at. locations 49.1 and 2,1. Weekly grab samples are.obtained at locations 49 and- 2 A,- ' A weekly grab ~- sample'is also obtained from daily composited grab !
: samples obtamed by the water treatment plant operator at location 5,.
(k) Two '(2) TLDs. are collected' quarterly and annually from each monitoringlocation;
. _
? Additional Notes:.
Sample points correspond to site numbers shown on maps.- . .
.
All: 1 131 analyses are performed within ' 40 hours of ' sample- collection if--
possible.-
- : All Air samples'are decayed for 72 hours before analyzing for Gross Beta.

Duquesno Light Company1991: Annual Radiological Environmental Report-
2. - Sun 3 mary of _Results 'i
' All results of this monitoring program are summarized-in Table 5-2. This tableis prepared . in the_ formal specified by: NRC Regulatory Guide 4.8 and in
__
accordance with Beaver Valley Power Station Operating License, (Appendix A,Technical Specifications). Summaries of results of analysis of each media arediscussed in Sections 5-8 through 5-H and an assessment of radiation doces arefound in Section 5-l. Table 5-3' summarizes Beaver Valley Power Station
: preoperational ranges for the various sampling media during the years 1974 and1975. -Comparisons- of preoperational data with operational data indicate the !
| ranges.of values are generally in good _ agreement for both pericds of time.1
Activity detected was attributed to _ naturally occurrir'0 radionuclides. - BVPSeffluents, medical procedures, previous nuclear weapons tests or to the normal
- statistical fluctuatior, for activities near the lower limit of detection (LLD).
- The conclusion from all program-data is that the operation of the Beaver ValleyPower Station has resulted in insignificant changes to the environment.
| 3. : Quahty Control Program '
L The Quality Control Program implemented by Duquesne Light Company to ,
i; _ assure reliable performance by the DLC contractor and the supporting QC data| are prcsented and discussed m- Section 3 of this report. The lower timits of :
detection for.various analysis for each media monitored by this program by-the !

-1, Charatterization of Air and Meteorology
The air in the vicinity.of the site contains pollutants typical for an industrial area.Air flow is generally from the Southwest m scmmer and from the Northwest inthe winter., ,
. 2. - . Air Samplin0 Program and Analytical Techniques
a; Program
The air is sampled for gaseous radiciodine and radioactive particulates ateach of ten (1) offsite air sampling stations. The locations of these stationsare listed in Table 5-1 and shown on a map in Figure 5-1.
Samples are collected at each of these s,tations by continuously drawingone cubic foot per minute of atmosphere air through a glass fiber filter and
? through a charcoal cartridge. The former collects airborne particulates;the latter is for > adiciodine sampling. Samples are collected for analysis-on a weekly basis.
The charcoal is used in the weekly analysis of airborne I-131. The filtersare analyzed each week for gross beta, then composited by station formonthly analysis by gamma spectrometry. They are further composited ina quarterly sample from each station for Sr-89 and Sr-90 analysis. In orderto reduce interference frorn natural radon and thoron radioactivities, allfilters are allowed to decay for a few days after collection prior to countingfor beta in a low background counting system.
~ b, Procedures
Gross Beta analysis is performed. by placing the filter papar from ?theweekly air sample in a 2" x - 1/4" planchet and counting it in a lowbackground, gas flow proportional counter,
, .
Gamma emitters are determined by stacking all the filter papers from eachmonitoring station collected during the month and scanning this compositeon a high resolution germanium gamma spectrometer.
Radiciodine (1-131) analysis is performed by a gamma scan of the charcoalin a weekly charcoal , cartridge. The activity is referenced to the
mid-collection time.1

|. The stream sediments consist largely of sand and silt. Soil samples may vary| from sand and sitt to a heav/ clay with variable amounts of organic material.i
i 2. _ Sampling Program and Analytical Techniques
a. Program -
River bottom sediments were collected semi-annually above theMontgomery Dam in the vicinities of the Beaver Valley discharge and
| above the New Cumberland Dam. A Ponar_ or Eckman dredge is used toL collect the sample. The sampling locations are also listed in Table 5-1
and are_shown in Figure 5-3.
| Soil samples were collected at each of ten (10) locations during 1991. At-1, each location 12 core samples (3~ diameter by 2~ deep) are gathered at
prescribed points on a 10 foot radius circle. Each location is permanentlymarked with reference pins. Each set of samples is systematically
, . selected by moving along the radius in such a manner as to ast,ure!- representative undisturbed samples. Sampling locations are listed in; Table 5-1 and are shown in Figure 5-3.
Bottam sediments and soils are analyzed for gross alpha and beta activity.strontium, and the gamma-emitting radionuclides.
b. Analytical Procedures
Gross beta - sediments and soils are analyzed for gross beta by mounting(. a 1= gram portion- of dried sediment in a 2" planchet. The sample is| counted in a low background, gas flow proportional counter. Self
- absorption corrections are made on the basis of sample weight.
Gross alnha activity of sediment or soil is analyzed in thp same manner asgross beta except that the counter is set up to count only alpha.
!
Gamma analysis of sediment or soil is performed in a 300 mi plastic bottlewhich is counted by a gamma spectrometer,

- Strontium 89 and 90 are determined by radiochemistry A wei hed sample0' of sediment or boil is leached with Nitric' Acid'HNOp A~ stable carrier is
added for determination of - recovery. Strontium. concentration andpurification is ultimately realized by precipitations of strontium nitrate in- !
. fuming nitric acid. Additional hydroxide precipitations and - bariumchromate separations are also used. The purified strontium is convertedto a carbonate for weighing and counting. Samples are counted soon after j
separation (5 - 7 days is allowed for yttrium ingrowth). Activities are ;
calculated on the bass of appropriate Sr-89 decay and Y-90. Separate I
mounts covered with a 80 mg/cm2 aluminum absorber are used forcounting in a low background beta counter.
3. Results and Conclusions 1
A summary of sediment and soil analysis is presented in Table 5-2..
a. Sediment
A total of six (6)-samples were analyzed for gross alpha and gross beta.Results were comparable to previous years.
. A total of six (6) samples were analyzed for Sr 89 and St 90. No Sr-89 or -Sr+90 was detected.
A total of six (6) sample were analyzed by gamma spectrometry. Naturallyoccurring K-40.- Ra-226, and Th-228 was found in every sample ano. Be-7was found in two samples. Small- amounts of Cs-137 from previousnuclear weapons test,were found in all river sediment samples ' including
. upstream above Montgomery Dam, which are unaffected by plant effluents.- Small amounts of Mn-54, Co-58, Co-60 and Cs 137 were detected in the
~
Beaver Valley Power Station discharge area and are attributable to station- releases. The-activity found in the station discharge area is consistent'
j with station data of authorized radioactive discharges. which were withinlimits permitted by the NRC license.
The analyses demonstrate that the Beaver Valley Power Station did notcontribute = a significant - increase - of radioactivity in the Ohio Riversediment. The positive results detected are attributable to authorized
; releases from the Beaver Valley-Power Station and-are characteristic ofthe effluent. These results confirm that the station assessments, prior to
'
authorizing radioactive discharges, are adequate -and' that theenvironmental monitoring program is sufficiently sensitive.

Strontium 90 analysis for feedstuff is performed by a procedure similar tothat described in 5-C.2.
L
L Radiciodine (1-13] is determined by radiochemistry. Stable iodide carrier! is first added -to a chopped sample which is then leached with sodium! hydroxide solution, evaporated to dryness and fused in a muffle furnace.
The melt is dissolved in water. filtered and treated with sodium
p hypochlorite. The iodate is then reduced to iodine with hydroxylamine| hydrochloride and is extracted into chloroform. It is then back-extracted
as iodide into sodium bisulfite solution and is precipitated as palladium|- iodide. The precipitate is weighed for chemical yield and is mounted on a
nylon planchet for low level beta counting.,

The sample from Searight Dairy was collected and analytod weekly forradiciodine using a procedure with a high rensitivity. Samples from eachof the other selected dairies were collected monthly when cows areindoors, and bi woekly when cows aro grazing. This monthly or bi weeklysample is analyzed for St 89, Sr 90, gamma emitters including Cs-137 (byhigh resolution germanium gamma spectroscopy) and 1-131 (lughsensitivity analysis),
.b. Procedure
,-
Radiciodine ' (1131) analyshi in milk was normally performed usmgchemically prepared samples and analyzed with a low-level beta countingsystem.
Qam,ma emitters are determined by gainma spectroscopy of a one literMarinelli container of milk.
Strontium analysis of milk is similar to that of other foods (refer to 5-C 2)except that rnilk samples are prepared by addition of Trichloracetic Acid(TCA) to produce a curd which is removed by filtration and discarded. Anoxalate precipitale is ashed for counting.
3. Results and Cone!usions
A summary of data is presented in Table S-2.
A total of one hundred sixty-six (166) samples were analyzed for I 131 during1991. All 1131 activities in milk were below the minimum detectable level.
A total of one hundred thirty four (134) samples were analyzed for St-89 andSr-90, - No St 89 was detected. Sr 90 levels attributable to previous nuclearweapons tests were detected in all samples and were within the normallyexpected range.
A total of one hundred thirty-four (134) samples were analyzed by gammaspectroscopy. The predominate isotope detected was naturally occurring K 40and was found in all samples. Cs 137 was detected in one (1) sample.
It was r'oted that the dalries with the highest annual mean activities were goaldairies, which are known to concentrate activities over a factor of two comparedto a cow dairy,,
All results were consistent with (or lower than) those obtained in - thepreoperational program.- These data confirm that the Beaver Valley PowerStation did not contribute to ra'dioactivity in mi!k in the vicimty of the site.

The tetrain in the vicmity of the Beaver Valley Power Stahon generally consistsof rough fulls with altitude varbrtions of 300 400 feet. Most of the land is woodnt

The princ$al geotogic features of the region are nearly flat faying sedimentary ;
t>eds of the Penrsylvania Age, Beds of nmestone alternate with sandstone ar'dshale with-abundant interbedded coa! layer s. Pleistocene glacial depositspartially cover the older sedimentary deposets in the northwest. Most of theregion is underlain by shate, sandstone, and r.ome coal beds of the Conemaugh
i
Formation. Outcrops of sandstone. shale, and li;nestone of the Allegheny |
Formation exist withm the Ohio River Valley and along major tributary streams. )Based on surveys. reported in previous annual reports, exposure rates ranged-from G-12 pR/hr Results for 1991 inuicated that background radwfinn contmuedin this range
2. . Locations and Analytical Procedures j
Ambient enternal radiation levels around the site were measured using ,
'thermoluminescent dosimeters (TLDs).i
In 1991 there were a total of forty-four (44) off site environmental TLD locations, j'
The locations of the TLDs are shown in Figure 5 7 through Figure 510. Thirteen(13) locations also have QC Laboratory TLDs. Both laboratories use calciumsulfato dysprosium. (CaSOgDy) in Teflon matrix.
The catc;Jm sulfate (CaSOjDy) TLDs were annealed shortly belore placing the .
TLDS in their field locations. The radiat'on dose accumulated in transit betweenthe field IMation and the laboratory was corrected by annealing control ,
dosimeters shortly before the field dosimeters were removed from the fieldlocation, when shipping the freshly _ annealed control dosimeters with theexposed field dosimeters to the laboratory 'nr readout at the same time. Alldosimeters were exposed in the field in a special environmental holder. .Thedosimetry system was calibrated by reading calcium sulfate dosimeters whichhave been exposed in an accurately known gamma radiation field,
in addition to' TLDs. Pressurized lon Chambers (PIC) provide continuous'
integrating monitoring. Sixteen PICS (Sites' 116) are part of the Sentri 1011Radiation Monitoring System which is a microcomputer based data acquisition !
system. Data from the stat ons are'sent at regular intervals to the CentralProcessing Unit were integrated doses are calculated. In addition there are four. ;
PICS .which are AC. Radiation Monitors. These are inspected weekly for i
integrator readings. The locations of the PICS are shown in Figure 511. ,

3. Results and Conclusions
Data obtair ed with the contractor TLD (CaSO :Dy in Teflon) during 1991 are i4
summarized in lable 5-2, and the quahty control TLD results are listed in
Table 31. Results for the PICS are hsted m Tablo 5 6.
The annual exposure rate of all off site TLDs averaged 0.16 rnR/ day in 1991. Asin previous years, there was some variation among locations and seasons aswould be expected Two TLDs were lost in the field during the year.
In 1991, loniting radiation dose determinations from TLDs averaged !approximately 58 mR for the year. This is comparable to prev >ous years. There I
was no evidence of anomalies that could be attributed to the operation of the |
Beaver Valley Power Station. The TLDs confarrn that changes from natural '
~
radiation invels. il any, are negligible. i

During 1991. fish collected for the radio:ogical monitoring program included |bass. carp. catfish. sheephead and shad. ;
2. Sampling Pro 0 ram and Analytical Techniques
a. Program
Fish samples are collected semi _-annually in the New Cumberlar'd pool ofthe Ohio River at the Beaver Valley effluent discharge point and upstreamof the ' Montgomery Dam. The edible portion of each diffrront species .|caught is analyzed by 9 mma spectroscopy. Fish sampling locations areshown in Figure 512.
b. Procedure,
t
A sample is prepared in a standard ta'ud 300 ml clastic bottle and scannedfor gamma emitting nuclidas with gamma spectrometry system whichutilizes a high resolution germanium detector.
3. Results and Conclusions
.
A sumtnary of the results of the fish monitoring data is provided in Table 5-2. )
A total of nine (9) samples were analyzed by garnma spectroscopy. Naturally ;'
occurring K 40 was found in all samples.

1. Description of Water Sources
The Ohio River is the main body of water in the area. It is used by the BeaverValley Power Station for plant make up for the cooling tower and for receivingplant liquid effluents. i
Ohio River water is a source of water for some towns both upstream and
downstream of the Beaver Valley Power Station site. It is used by severalmunicipahties and industries downstream of the site. The nearest user of theOhio River as a potable water source is Midland Borough Mumcipal WaterAuthority. The intake of the treatment plant is approximately 1.5 rulles
downstream and on the opposite side of the river. The next downstream user isEast Liverpool, Ohio which is approximately 6 miles downstream. The heavyindustries in Midland, as well as others downstream use river water for coolingpurposes. Some of these plants also have private treatment facilities for plant
- sanitary water.
Ground water occurs in large volumes in the gravel terraces which lie alon0 theriver, and diminishes considerably in the bedrock underlying the site. Norrialwell yields in the bedrock are less than 10 gallons per minute (gpm) withoccasional wells yielding up to 60 gpm.
In General, the BVPS site experiences cool winters and moderately warmsummers with ample annual precipitation evenly distributed throughout the year.The record mean annual precipitation for the area is 36.40 inches based on 1972to 1990 data collected at the Pittsburgh international Airport,

2. Sampling and Analytical Techniques
'
a. Surface (Raw River) Water
The sampling program of river water includes five (5) sampling pointsalong the Ohio River. Raw water samples are normally collected at theEast Liverpool (Ohio) Water Treatment Plant [ River Mile 412] daily andcomposited into a monthly sample. Weekly grab samples are taken fromthe Ohio River at the followmg locations: upstream of Montgomery Dam[ River Mile 31.8); and near the discharge from the Beaver Valley Power *
Station [ River Mile 35 0]. Two automatic river water samplers are at the |'following locations: Upstream of Mont0cmery Dam ',; River Mile 29.6); andat J&L Steel's river water intake [ River Mile 36.2]. The automatic sampiertakes a 20-40 mi sample every 15 minutes and is collet.ted on a weeklybasis.. The weekly grab samples and automatic water samples are
i
composited into monthly samples from c1ch location. In addition, o
quarterly composite sample is prepared for each sample point.
Tne weekly composites from the automatic river watbr sampler upstream i
at Montgomery Dam are analyzed for 1131. +
The monthly composites are analytod for gross alpha, gross beta, andgamma emitters. The quarterly composites are analited for H 3. Sr 89. )
Sr 90, and Co-60 (high sensitivity). )Locations of each sample point are shown in Figure 5-13
b. Drinking Water (Public Supplies) '
Drinking (treated) water is collected at bnth Midland (PA) and East,
Liverpool (OH) Water Treating Plants, An automatic sampler at each'
location collects 20-40 ml every 20 minutes. These intermittent samples i
are then composited into a weekly sample. A weekiy grab sample is alsotaken at the DLC Training Building in Shippingport, PA. The weeklysample from'each location is analyzed by gamma spectroscopy. Theweekly samples are also analyzed for 1131.
Monthly composites of the weekly samples are analyzed for gross alpha.gro.3 beta, and by gamma spectrometr/. Quarterly ccmposites areanalyzed for H 3, St 89, Sr 90 and Co 60 (high sensitivity). Locations ofeach sample point are shown in Figure 513.

Tritium is determined in water sampkts by converting 2 ml of the sampleto hydrogen and counting the activity in a 1 liter low level gas counterwhich is operated in the proportional range in anti-coincidence rnode.
Radicioding (1131) analysis in water was normally perfmmed usingchemically prepared samples and analyzed with a low-level beta countmgsystem.
'3. Results and Conclusions i
iA summary of results of all analyses of water samples (surf ace, drinking, groundand precipitation) are provided by sample type and analysis in Table 5 2. Theseare discussed below.
a. Surface Water ;
A total of forty eight (48) samples were analyzed for gross alpha and gross*
beta. Alpha activity was detected in one of the samples at a levelcomparable ' to preoperational values. Positivo beta results above ,
preoperational levels were detected in the OVPS discharge area and areattributable to station releases.- The beta activity found in the station ;
discharge area is consistent with station data of authorized radioactivedischarges and were ,within limits permitted by the NRC license.
.
A total of sixteen (16) samples were analyzed for H 3, Sr 89 and Sr-90 as Iwell as a high sensitivity analysis for Co-58 and Co 60. Positive Co-58 and- -'
tritium results were detected in the BVPS discharge area and are
attributable to station releases, All other samples taken-upstream anddownstream were within 'preoperational levels. The activity found in thestation discharge area is consistent with station data of authorizedradioactive ' discharges and were within limits permitted by the NRClicense, e

A tota, of fifty two (52) samples were analyzed for | 131 using a highlysensitive technique. Trace levels of I 131 were rueasured in eighteen (18)of the weekly samples. Th9 results were slightly above the minimumdetectable activity. The positive results were detected at a contre' locationabove the BVPS discharge and could not be attributed to plant releases. ;
The results may be attributed to medical procedures and the exported ivariabihty in the analyses results of very low levels of activity.
b. Drinking Water
A total of thirty six (36) samples were analyzed for gross alpha and gross.
beta. All results were within a normal range,
A total of twelve (12) samples were analyzed for H 3, St 89 and St 90 as~ well as a high sensitivity analysis for Co-60. No Sr 89. Sr-90, or Co-60were detected. The H 3 data were withm the preoperational rangeindicative of normal environmental levels.
A total of another one hundred hfty-seven (157) samples were analyzeo bygamrna spectrometry. No gamma emitting radionuclides were detected.

l. listimates of Radiation Dose to Man [
t, Pathways to Man Calculational Models
i
The radiation doses to man as a result of Beaver Valley operations werecalculated for both gaseous and liquid effluent pathways using NRC computer !
codes XOODOQ2 GASPAR, and LADTAP. Dose factors listed in the ODCM wereused to calculate doses to maximum individuals from radioactive noble gases indischarge plumes. Beaver Valley effluent data, based on sample analysis inaccordance with the schedule set forth in Appendix A ot the BVPS license. wereused as the idionuclide activity input.
Each radionuclide contained in the Semi-Annual Radioactive Effluent ReleaseReport (noble gases, particulates, radiciodines and tritium) were included assource terms when they were detected above the LLD values. All LLD values
reported by Beaver Valley Power Station are equal to or lower than thoserequired by the Technical Specifications.
All gaseous effluent r > leases, including Auxiliary Building Ventilation, wereLincluded in dose assessments. The release activities are based on laboratory
,
analysis. When the activity of noble gas was below detection sencitivity, eitherthe inventory based on its MDL or an appropriate but conservative ratio to eitherrneasured activity of Kr-85 or Xe 133 was used. Meteorological data collected by '
the Beaver Valley Power Station Meteorolo0y System was used as input toXOOOOQ2 which in turn provided input for GASPAR. Except when more recent '
or specific data was available, all inputs were the same as used in tae BeaverVsliey Power Station Environmental Statements or in Regulatory Guide 1.109.Tb3 airborne pathways evaluated were beta and gamma doses from noble gasplumes inhalation, the " cow-milk child", and other ingestion pathways,
All potentially radioactive liquid effluents, including steam generator blowdown,are released by batch rnode after analysis by gamma spectrometry usingIntrinsic Germanium detectors. Each batch is diluted by cooling tower blowdown -
water prior to discharge into the Ohio River at the Beaver Valley Power Wionouttall (River Mile 35.0), The actual data from these analyses are tabulated andused as the radionuclide activity input term in LADTAP. A hypothetical realindividual for liquid pathways is located at Midland. Except when more recent or ,
specille data for the period is available, all other input to LADTAP are obtainedfrom the Beaver Valley Power Station Environmental Statement or RegulatoryGuide 1109. Pathways, which were evaluated, are drinking water, fishconsernpuon, shoreline recreation, swimming, and boating.

The doses which are calculated by the model described above are to a j-

| b. Upon implementation of the Unit 2 Technjcal Specifications and inception !
of the liquid discharge procedures at 'Jnit 2 on July 24.1987, the discharge ;

reactor specific dose limits that are equal to the limits in 10 CFR Part 50. .

,
3. Results of Calculated Radiation Dose to Man - Atmospheric Releases,
The results of calculated radiation dose to the maximum exposed individuals forBVPS airborne radioactive effluents during 1991 are provided in Table 5-9. Thedoses include the contribution of all pathways. A 50 mile population dose is alsocalculated and provided in Table 5 9. H-3 is the primary radionuclide *
contributions to these doses.
The results are compared to the BVPS annual limits in Table 5-9. As in the i
ilquid discharge limits, the gaseous effluent limits are reactor specific; i.e.. Unit 1 -
and Unit 2 have reactor specific dose limits that are equal to the limits in 10 CFR,
Part 50, Appendix 1. Therefore, the annual limits listed in Table 5 9 are specificto this report only, and were derived by multiplying the individual Technical !
- Specification reactor limits by a factor of two (2). The results show comphancewith the BVPS annual limits. i

4. Conclnsions . (Beaver Valley Power Station)
Based upon the estimated dose to individuals from the natural backgroundradiation exposure m Table $ 7, the incremental increase in total body dose tothe 50amle population (4 million people), from tho operation of Beaver ValleyPower Station Umt 1 and 2, is less than 0.0001'. of the annual background.
The calculat(. . doses to the pt.blic from the operation of Beaver Valley PowerStation iUnit 1 and 2, are below BVPS annual hmits and resulted in only a smallincremental dobe to that which area residents already received as a result ofnatural backgrouni The doses constituted no rneaningful risk to the pubbc. {

Appendix A
Interlaboratory Comparison Procram Results
Teledyne Isotopes Midwest Laboratory (formerly Hazleton Environmental Sciences) has participated ininterlabordory comperison (crosscheck) programs since the formulation of its quality control program inDecember 1971, These programs are operated by agencies which supply environmental type samples (e.g.,milk or water) containing concentrations of radionuclides known to the issuing agency but not toparticipant laboratories, The purpose of such a program is to provide an independent check on thelaboratory's analytical procedures and to alert it to any possible problems.
Participant laboratories' measure the concentration of specified radion alldes and report them to theissuing agency. Several months later, the agency reports the known values to the participant laboratoriesand specifies control limits. Results consistently higher or lower than the known values or outside thecontrol limits indicate a need to check the instruments or procedures used.
The results in Table A-1 were obtained through participation in the environmental wmple crosscheckprogram for milk, water, air filters, and food samples during the period January 1988 through November1991. This program has been conducted by the U.S. Environmental Protection Agency Intercomparisonand Calibration Section, Quality Assurance Branch, Environmental Monitoring and Support Laboratory,Las Vegas, Nevada.
The results in Table A-2 were obtained for thermoluminescent dosimeters (TLDs) during the period 1976,1977,1979,1980,1984, and 1985-86 through participation in the Second, Third, Fourth, Fifth, Seventh, andEighth International Intercomparison of Environmental Dosimeters under the sponsorships listed inTable A-2. Also Teledyne testing results are listed.
Table A-3 lists results of the analyses on in house spiked samples.
Table A-4 lists results of the analyses on in-house " blank" samples.
Attachment B lists acceptance criteria for " spiked" samples.
