Items 3.1.l(2), 3.1.1(4), 3.2.2(1), and 3.2.2(2)Fire Barrier Penetration Seal Upgrading
Northern States Power Company will upgrade fire 'sarrier seals in safety,
related areas of the Prairie Island plant to a rating at least equalto the worst case fire severity present on either side of each barrier. Inaddition, seals in the following arear will be upgraded to a 3-hour rating:
a. Area 66 barriers adjacent to turbine buildingb. Area 69 and 70 barriers adjacent to auxiliary building
Elevation 735 auxiliary building barriers adjacent to turbine buildingc.
d. Area 61 barriers shared with the auxiliary buildingBarriers between diesel rooms and auxiliary buildinge.
f. Barriers between safety related areas and turbine building notlisted above
A description of the testing program developed to qualify various methodsof seal upgrading was provided for NRC Staff review and comment on November30, 1979. Drawings of proposed seal upgrade methods were also submitted.
Three slabs of 12 inches thick concrete were constructed containing a totalof 38 test penetrations. These penetrations were constructed to simulatethe configurations of existing and proposed upgrade designs, includingpairs of penetissions for non-symetrical configurations. The tes t penetra-tions include configurations like those in the plant and configurationslike th *se in the plant with add-on fire seal materials covering theexisting seal material. In some test penetrations a new seal materialwas substituted for that used in the plant.
The test slabs were subjected to a test by an independent testing laboratoryto IEEE 634-1978, IEEE Standard Cable Penetration Fire Stop QualificationTest, which replaces ASTM E 119 for nuclear power plant cable penetrationsand which uses the time temperature curve from ASTM E 119.
Summaries of the test reports for the three slabs are attached. Thedetails of the test results are considered proprietary to Northern StatesPower Company because of the expense involved in conducting this program.Complete reports are available on site for review by Inspection and Enforce-ment or other NRC personnel.
The reports have been reviewed in detail by our consulting engineer forthis project. All penetrations in safety related areas of the plant willbe surveyed. Where deficient, the seals will be upgraded with a qualifiedadd-on modification or replaced with a qualified seal.

SIIMMARY
On 20 March 1980, twenty-three block-out penetrations decigned
by Nuclear Services Corporation for Nortbern States Power Company and
installed by Insulation Consultants and Management Services (ICMS),
Incorporated and Southwest Research Institute were exposed to a three-
hour fire endurance qualification test following the ASTM E119-76 time /
temperature curve.
The purpose of the test was to obtain a three-hour fire racing
for existing referenced retrofit fire stop designs in~ accordance with
ASTM E119-76 time / temperature requirements. In addition, a hose stream
test as ' described in Appendix VI, Section 5.3.12 of IEEE 634 was to be
applied.
Penetration seal construction consisted of vurious loaded cable
tray and pipe sleeve openings sealed with ther=al insulating wool, bulk.
insulation fiber, silicone and polyurethane foams, insulating boards
such as Marinite, and in sone cases, coatings were applied to the
finished seals.

DESCRIPTION
i
A series of twenty-three block-out cpenings were cast into the
test slab. Three penetrations consisted of 14" x 42" cable tray open-,
ings, and the remainder consisted of 6", 8", and 10" diameter pipe sleeve
openings. A detailed description of each opening is contained in the
discussion of the test slab construction, and the slab layout is shown
in Figures 1 and 2.
All openings were cast into an 8' x 10' x 12" chick concrete
slab. Once cured, the various penetration seal materials identified in
Figure 3, and cabling as described in Appendix I were installed. , Basic
cable loading is shown in Figure 4. The penetration seal materials were
allowed to cu're' prior to the fire exposure test.
The test slab was placed on a horizontal furnace, and exposed to
the standard ASTM E119 time / temperature curve. After three hours the
test slab was lifted in a horizontal position for the hose stream test
and then moved to an area adjacent to the furnace, where it was put on
blocks to cool and view.

TEST SLAB
A. Construction
A floor section form (8' x 10' x 12" chick) was constructed
of 12" steel channel with a double mat of No. 8 rebar on 10" centers.
A series of twenty-three penetration openings were cast into the slab.
Three of the penetrations were 14" x 42" cable tray openings. Five
penetrations consisted of 6" pipe sleeve pairs into which were sealed
50 percent fill cable bundles. Eight penetrations consisted of 8"
pipe seals into which were sealed 50 percent fill cable bundles. Two
penetratibns were 8" pipe sleeves with a 1" and a 2" conduit sealed
therein. Four penetrations were 10" pipe sleeves with 3" pipes sealed
within, and one penetration was a 10" pipe sleeve with a 5" steel pipe.
The concrete (f, = 3000 psi) was poured on 20 December 79 and
cured for one week at 400'F, using an enclosure constructed for this
purpose. After the concrete had cured, cable tray supports were welded
to the basic framework. Details of the steel framing and slab layout
are shown in Figure 5.
B. Penetration Loading
All penetrations were loaded as defined by the Northarn States
Power Company Specifications, Revision 3, dated 7 February 1980. Table
1 shows the type and number of cables used in each opening.
C. Sealing of Penetrations
All penetrations were filled by ICMS and SwRI personnel using
the materials defined in the referenced specifications, which are re-
produced in Appendix I. A detailed listing of installation procedures
used during the seal preparation also appears in Appendix I. Photographs

TEST FACILITY
The floor penetration assembly fire resistance test was conducted
using a horizontal furnace with an open area of 8 x 10 ft. (See Figure
30). A flue gas opening was provided on one end. Eight (8) Maxon self-
aspirating -burners were mounted in the sides of the furnace. Eight (8),
furnace temperature thermocouples were located 2-1/2 f t inside each wall
at 2 foot centers with the first pair of thermocouples 1-1/2 ft fron
i the flue end of the furnace at the 24 inch elevation. Eighty-seven (87)
ther= occupies on the unexposed side and imbedded in the seal materials
of the s2bject penetration seals were connected to multi-point tem-
I perature recorders with a range of zero to 2000*F and a digital printout!
of 60 points per minute. (See Appendix IV and V). All gas flow to the
hirners was controlled manually and continuously indicated by the average
of six furnace temperature thermocouple readings taken at 12 inches from
the exposed specimen surface. These average temperatures are shown in
Figure 31 and Table 2. The temperatures recorded from the imbedded and
; unexposed side thermocouples are shown in App c.!!x IV.
Since the test was conducted outdoors, a building was erected
around the furnace to meet ASTM E119 standards. This structure was
adequate to prevent excessive air currents over the unexposed surface--
of the slab. The outside temperature was approximately 68'F at the
start of the test.

TEST PROCEDURES,
The prepared floor penetration slab with fire stop materials inThe temperatureplace was pt::ca in position on top of the farnace.
recorders were turned on, natural gas was supplied to themulti-point
burners, ignited, and the test clock was started. The uncxposed surface
was continually observed for penetration by flame or hot gases and itsAt the endtemperature monitored, by using the multipoint recorders.
of the three hour fire exposure period, the fuel gas was shut off and,
as quickly as possible, the enclosure building was removed and the test
slab was 'lif ted from the furnace, remaining in a horizontal position.
A 30* spray stream supplied from a 1-1/2 inch fire hose with a spray
scream setting and 75 rst nozzle pressure and 75 gpm delivery was then
directed at the floor penetrat' ion fire stops from a distance of 10 feet
This hose stream test is identifiedto conduct the hoee strean test.
on page 13, Section 5.3.12 of IEEE 634-1978 (see Appendix VI) and is
co=monly referred to as the "NEL-PIA Hose Stream Test." The required
hose stream application tLme for penetrations installed in a 10 x 8 f t
slab was 2 minutes. The time / temperature record of the test is shown
in Figure 31 and Table 2. Figures 30 and 32 show an exploded view of
the test setup.

Post Test Observations1. There was no passage of flame through any penetration duringthe fire exposure test.
2. There was passage of light smoke through the seals, but smokecoming through was cool to the touch.
3. There was no passage of water or flame through any penetrationduring the hose stream test.
B. Summary of Test Results
A fire stop shall be considered as meeting the requirements
far acceptable performance when it remains in the opening during the
fire endurance test and hose stream test within the following limi-tations:
1. The fire stop shall have withstood the fire endurance
test without permitting the passage of flame, or the occurrence of
flaming on any element of the unexposed surface of the assembly for
a period equal to the hourly classification for the fire stop.2. The fire stop shall have withstood the fire endurance test
and hose stream test without developing an opening that would permit
a projection of water from the stream beyond the unexposed surface.3. The transmission of heat through the fire stop during the fire
endurance test for any recorded temperature on its unexposed surface
shall not exceed 700 F'on penetrations involving cable.
Accordingly, the following shows the performance of the pene-,
trations for the test period of three hnurs as documented in the test
observations and in Appendix IV.

ISUMMARY !
On 24 March 1980, nine block-out penetrations designed by Nuclear
Services Corporation (NSC) for Northern States Power Company and install-
ed by Insulation Consultants and Management Services (ICMS), Carboline Co.
and Scuchwest Research Institute (SwRI) were exposed to a three-hour fire
endurance qualification test following the ASTM E119-76 time / temperature
curve.
The purpose of the test was to obtain a three-hour fire rating for
existing referenced retrofit fire stop designs in accordance with ASTM
E119-76 time / temperature requirements. In addition, a hose stream test as
described in Appendix VI, Section 5.3.12 of IEEE 634 was to be applied.
Penetration seal construction consisted of various loaded cabla tray
and pipe openings filled with thermal insulating wool, silicone and poly-
urethane foams, marinite board, and in some cases coatings were applied to
the finished seals.

DESCRIPTION
A series of nine openings were cast into the test slab. Two
penetrations consisted of 48" x 36" cable tray openings; six penetrat-
ions were each 14" x 14" blockout openings; and one penetration con-
sisted of a 6 inch conduit pipe opening. (See Figures 1 and 2).
All penetrations were cast into an 8 ft. x 10 ft. x 12 in. thick
concrete slab. Once cured, the various penetration seal materials
and cabling as described in Appendix I were installed. (See Figure 3.)
These were allowed to cure prior to the actual test.
The test slab was placed on a horizontal furnace and exposed to
the standard ASTM E119 time / temperature curve. After three hours the
test slab was lif ted in a horizontal position for the hose stream test
and then moved to an area adjacent to the furnace, where it was put-on
blocks to cool and view..

A. CONSTRUCTION
A floor section form (8 ft. x 10 ft. x 12 in. thick) was constructed
of twelve inch steel channel with a double mat of No. 8 rebar on ten inch
centers. A series of nine penetration openings were cast into the slab,
6 inch diameterSix were 14 inch x 14 inch cable tray openings; one was a
conduit pipe opening; and two were 12 square ft. cable tray openings,
3 ft. x 4 ft.
The concrete (f = 3000 psi) was poured on 20 December 1979 and cured
for one week at 400 F, using an enclosure constructed for this purpose.
After the concrete had cured, cable tray supports were welded to the
basic framework. Details of the steel framing are shown in Figure 4.
B. FENETRATION LOADING
All penetrations were loaded as defined by the Northern States
Power Company Specifications, Revision 3, dated 7 February, 1980.
Table I shows the type and number of cables used in each opening.
C. SEALING OF PENETRATIONS
All penetrations were filled by ICMS and SwRI personnel using the
materials defined in the Northern States Power Co. Specification. The
Specification is reproduced in Appendix I. A detailed listing of in-
sta11ation procedures used during the seal preparation also appears in
Appendix I. Photographs taken during the course of seal installation
are shown in Appendix II. Quality Control documents are in Appendix III.
Drawings of the penetration assemblies appear in Figures 5 through 14.

TEST FACILITY
The flocr penetrativn assembly fire resistance test was
conducted using a horizontal furnace with an open area of
8 x 10 ft. (See Figure 15). A flue gas opening was provided
on one end. Eight (8) Maxon self-aspirating burners were
mounted in the sides of the furnace. Eight (8) furnace temp-
erature thermocouples vera located 2 1/2 ft. inside each side
wall at 2 ft. centers with the first pair of thermocouples
1 1/2 ft. from the flue end of the furnace at the 24 inchelevation. Thirty-four (34) thermocouples on t~e unexposed
side and imbedded in the seal materials of the nit a subject
penetration seals were connected to multi-point temperature
recorders with a range of 0 to 2,000*F and a digital printout
of 60 points per minute. (See appendix IV and V). All gas
flow to the burners was controlled manually and continuously
indicated by the average of six furnace temperature thermoccuple
readings taken'at 12 in. from the exposed' specimen surface.
These average temperatures are shown in Figure 16 and Table 2.
The temperatures recorded from the imbedded and unexposed side
thermocouples are shown in Appendix IV.
Since the test was conducted outdoors, a building was
erected around the furnace to meet ASTM E119 standards. This
structure was adequate to prevent excessive air currents over
the unexposed surface of the slab. The outside temperature
was approximately 60*F at the start of the test.

TEST PROCEDURES
The prepared floor penetration slab with fire stop materials in
place vs.s placed in position on top of the furnace. The temperature
multi-point recorders were turned on, natural gas was supplied to
the burners, ignited, and the t___ alock was started. The unexposed
surface was continually observed for penetration by flame or hot gases
and its temperature monitored, by using the multipoint recorders.
At the. end of the three-hour fire exposure period, the fuel gas was
shut off and as quickly as possible the enclosure building was re-
moved and the test slab was lifted from the furnace, remaining in a
horizontal position. A spray stream supplied from a 1-1/2 inch fire
hose with a 30' spray stream setting and 75 psi nozzle pressure and
75 gpm delivery was then directed at the floor penetration fire stops
from a distance of 10 feet to conduct the hose stream test. This hose
stream test is identified on page 13, Section 5.3.12 of IEEE 634-1978|' (See Appendix VI) and is commonly referred to as the "NEL-PIA Hose
Stream Test". The required hose stream application time for penetrations
installed in a 10 x 8 ft. slab wzs 2 minutes. The time / temperature re-
cord of the test is shown in Figure 16 and Tablt 2. Figures 15 and 17

B. SUMMARY OF IEST RESULTS
A fire stop shall be considered as meeting the requirements for
acceptable performance when it remains in the opening during the fire
endurance test and hose stream test within the following limitations:
1. The fire stop shall have withstood the fire endurance test
without permitting passage of flame, or the occurrence of flaming on
any element of the unexposed surface of the assembly for a period equal
to the hourly classification for the fire stop.
2. The fire stop shall have withstood the fire endurance test
| and hose stream test without deveieping an opening that would permit a|
| projection of water from the stream beyond the unexposed surf ace.||

3 The transoission of heat through the fire stop during the
endurance test for any ::cerded temperature on its unexoosed surface
shall not exceed 700*F on penetrations involving cable..
Accordingly, the following shows the performance of the pene-
trations for the test period of three hours as documented in the test
observations and in Appendix IV.

SOD'.ARY
on 25 March,1980, six block-out penetrations designed by Nuclear
Services Corporation for Northern States P;wer Company and installed'
by Insulation Consultants and Management Services (ICMS), Carboline Co.4 and Southwest Research Institute were exposed to a three-hour fire en-
durance qualification test following the ASTM E11^-76 time / temperature
curve.
The purpose of the test was to obtain a three-hour fire rating for
existing referenced retrofit fire stop designs in accordance with ASTM
E119-76 time / temperature requirement . In addition, a hose stream test
as described in Appendix VII, Section 5.3.12 of IEEE 634 was to be
applied. ,
Penetration seal construction consisted of various loaded cable
tray and pipe openings filled with thermal insulating wool, silicone4
and polyurethane foams, marinite board, and in some cases coatings
were applied to the finished seals.

DESCRIPTION
A series of six penetration openings were cast into the test slab.
Three penetrations consisted of 30" x 45" cable tray openings; two
penetrations were each 14" x 42" cable tray openings; and one pene-
tration was a 10 inch diameter pipe sleeve. (See Figures 1 and 2).
All penetrations were cast into an 3 ft. x 10 ft. x 12 inch thick
concrete slab. Once cured, the various penetration seal materials and
cabling as described in Appendix I were installed. Basic cable load-
ing is shown in Figure 3. The penetration seal macerials were allowed
to cure prior to the actual test.
The test slab was placed on a horizontal furnace and exposed to
the standard ASTM E119 time / temperature curve. After three hours the
test slab was lif ted in a horizontal position for the hose st:,eam test
and then moved to an area adjacent to the furnace, where it was put on
blocks to cool and view.

TEST SLAB
A. Construction
A floor section form (8 f t x 10 ft x 12 in thick) was constructed
of twelve inch steel channel with a double mat of No. 8 rebar or ten
inch centers. A series of six penetration openings were cast into the
slab. Three of the penetrations were 30" x 45" cable tray openings;
two were 14" x 42" cable tray openings; and one was a 10" diameter
(Sch. 40) pipe sleeve into which was sealed a capped 3 inch steel pipe.
The concrete (f, = 3000 psi) was poured on 20 December, 1979 and
cured for one week at 400*F, using an enclosure constructed for this_
purpose. After the concrete had cured, cable tray supports were welded
to the basic framework. Details of the steel framing and slab layout
are shown in Figure 4
B. Penetration Loading
All penetrations were loaded as defined by the Northern States
Power Company Specifications, Revision 3, dated 7 February,1980.
Table 1 shows the type and nunber of cables used in each opening.
C. Sealing of Penetrations
All penetrations were filled by ICMS, Carboline and SwRI personnel
using the materials defined in the Northern States Power Co. specifica-
tions. The specification is reproduced in Appendix I. A detailed list-
ing of installation procedures used during the seal preparation also
appears in Appendix I. Photographs taken during the course of seal in-
\| stallation are shown in Appendix II. Quanlity control documents are in
| Appendix III. Drawings of the penetration assemblies appear in Figures
5 throuf,h 11.

TEST FACILITY
The ficor penetration assembly fire resistance test was conducted
using a horizontal furnace with an open area of 8 r 10 8:. (See Figure
12). A flue gas opening was provided on one end. Eight (8) Maxon self-
aspirating burners were mounted in the sides of the furnace. Eight (8)
furnace temperature thermocouples were located 2-1/2 f t inside each
side wall at 2-ft centers with the first pair of thermocouples 1-1/2
ft from the flue end of the furnace at the 24 inch elevation. Thirty-one
(31) thermocouples on the unexposed side and imbedded in the seal mat-
erials of the six subject penetration seals were connected to multi-
point temperature recorders with a range of 0 to 2,000*F and a digital
printout of 60 points per minute. (See Appendix IV and V). All gas
flow to the burners was controlled manually and continuously indicated.
by the average of six furnace termperature thermoccuple readings taken
at 12 in, from the exposed specimen surface. These average temperatures
are shown in Figure 13 and Table 2. The temperatures recorded from the
imbedded and unexposed side thernocouples are shown in Appendix IV.
Since the test was conducted outdoors, a building was erected
around the furnace tc meet ASTM E119 standards. This structure was
adequate to prevent excessive air currents over the unexposed surface
of the slab. The outside temperature was approximately 70*F at the
start of the test.

TEST PROCEDURES
The prepared floor penetration slab with fire stop materials in
place was placed in position on top of the furnaco. The temperature
multi-point recorders were turned on, natural gas was supplied to the
burners, ignited, and the test clock was started. The unexposed surface
was continaully observed for penetration by flame or hot gases and its
temperature monitored, by using the multipoint recorders. At the end of
the three-hour fire exposure period, the fuel gas was shut off and, as
quickly as possible, the enclosure building was removed and the test
slab was lifted from the furnace, remaining in a horizontal position.
A spray stream supplied from a 1-1/2 inch fire hose with a 30 * spray
stream setting and 75 psi nozzle pressure and 75 gpm delivery was then
directed at the floor penetration fire stops from a distance of 10 feet
to conduct the hose stream test. This hose stream test is identified
on page 13, Section 5.3.12 of IEEE 634-1978 (See Appendix VI) and is
commonly referred to as the "NEL-PIA Hose Stream Test". The required
hose stream application cima for penetrations installed in a 10 x 8 ft.
slab was 2 minutes. The time / temperature record of the test is shown
in Figure 13 and Table 2. Figures 12 and 14 show an exploded view of the
test setup.

Post Test Observations
1. There was no passage of flame through any penetrationduring the fire exposure test.
2. There was passage of light smoke through the seals, butsmoke coming through was cool to the touch.
3. There was no passage of water through any penetrationduring the hose stream test.
B. SUMMARY OF TEST RESULTS
A fire stop shall be considered as meeting the requirements
for acceptable performance when it remains in the opening during
the fire endurance test and hose stream test within the following
limitations:
1. The fire stop shall have withstood the fire endurance test
without permitting the passage of flame, or the occurrence of flaming
on any element of the unexposed surface of the assembly for a period
equal to the hourly classification for the fire atop.
2. The fire stop shall have withstood the fire endurance test
and hose stream test without developing an opening that would permit
a projection of water from the stream beyond the unexposed surface.
3. The transmission of heat through the fire stop during the
fire endurance test for any recorded temperature on its unexposed|
surface shall not exceed 700 F on penetrations involving cable.I:
Accordingly, the following shows the performance of the pene-
trations for the test period of three hours as documented in the test
observations and in Appendix IV.

Subject: Pyrotronics Fire DetectorsResponse to Burning Cables
Dear Don:
Please forgive our delay in conducting fire tests on the variouscable samples you sent to us quite some time ago. As you know,we were and still are having some leakage problems in our smokeexhaust system 19 the fire test room. However, we recentlystarted conducting these tests one at a time at off scheduledworking hours and fically have completed the series.
The enclosed test report includes the submitted cable samplesas listed below, and we recorded the responses of only our highvoltage detector models 3/5A and 5B. These detectors are thetype installed in P.I.N.P.S.
Cable Type Test Numbers.

Please note that the last listed test of Okonite EPR was conductedpreviously for Commonwealth Edison. We thought that this informa-tion would be acceptable for your purpose as the cable is of thesame type and manufacturer.

The results of the tests proved very positive and acceptablefast response by the detectors to both flame and heat exposureto all sample cable types. As we get more experience with thesekinds of tests, it is becoming obvious that there is very littledifference in the time of detector response to cable insulatingmaterials.
' We believe that this information will satisfy your needs, how-ever if any questions arise or if any further details are needed,please let me know.
Very truly yours, ,
