1.0 ,TNTRODUCTION

*If a loss-of-coolant accident (LOCA) should occur in a light water reac-

tor (LWR), the thermal stored energy (short term) and decay heat (long term)' of the fuel rods become the driving forces for fuel damage. To assess the.

amount of energy that would be present in the core of a commercial LWR should

| a LOCA occur, the U.S. Nuclear Regulatory Commission (NRC) must rely on com-puter codes. These codes are designed to account for fuel type, fuel and clad-

! ding dimensions, coolant conditions, power level, operating history, and a hostI of other considerations. However, these codes are only as reliable as the data

bases that are used to build them and to verify their results.,

The Experimental Support and Development of Single-Rod Fuel Codes Programwas established primarily to develop a well-characterized data base to assuresuch reliability. The program was begun at Pacific Northwest Laboratory(PNL)(a) in 1974 by the Fuel Behavior Research Branch of the NRC. The datagenerated under this program is used in the development and verification ofthe NRC audit codes GAPCON-THERMAL and FRAPCON (Lanning et al., January 1978;

Berna, Bohn and Coleman, November 1978).'

To date, this program has built two instrumented fuel assemblies and;

irradiated them in the Halden Boiling Water Reactor (HBWR) located in Halden,Norway. The first of these assemblies, IFA-431, was irradiated from June 1975 '

i to February 1976 and obtained an assembly average burnup of 389 GJ/kg1

(4.5 GWd/ MTM). The second assembly, IFA-432, is identical in design, and itsirradiation began in December 1975. This assembly is still in the reactor, andit is providing data at high fuel burnup.ID) The data obtained from both ofthese assemblies has been consistent, and it has been useful for verifying

' existing models, developing new models, and developing new techniques foranalysis of fuel rod data.

,

To continue the work begun with IFA-431/432, and to fill in information,

gaps left by those assemblies, a third assembly has now been built and wascharged into the HBWR in November 1978. This assembly, designated IFA-513, is

a joint venture of the Halden Reactor Project and NRC/PNL. Halden is provid-ing the assembly design, assembly fabrication, and irradiation services. NRC/

PNL is providing the fuel and cladding, postirradiation examination, and anal- *

ysis of the expertinental data.

The assembly, IFA-513, is designed to meet a number of needs. First, two''

rods tre filled with gas mixtures that were not used in IFA-431/432. Theserods will provide additional data on the question of fuel temperatures andstoied energy as a function of fuel rod design. Next, since statistical dif-

ferences can occur between supposedly identical fuel rods, IFA-513 containsthree identical rods to be used in evaluating this question. Third, all rodsare equipped with continuous response gas pressure transducers to evaluate fis-sion gas release. Next, continuing de!elopment of transient temperature anal-ysis techniques will permit evaluation of the changing behavior of the fuelrods. And finally, the rods will be shipped to the Power Burst Facility atIdaho National Engineering Laboratory for additional testing.

2.0 OBJECTIVES AND RATIONALE

When the Experimental Support and Development of Single-Rod Fuel Codes*

Program (previously called the Verification of Steady-State Codes Program) wasbegun in 1974, several areas in the LWR steady-state data base were deficient.,

Of particular concern was a lack of the following; well-defined temperature /power data, information on temperature effects of densification, and data fromrods with extended burnup. Instrumented fuel assembly 513 is designed to com-

plement and extend the data and analysis begun by IFA-431/432 in these and

other areas. Specifically, the primary objectives of IFA-513 are to:

extend the NRC/Halden test series to include rods with known gas mixturese

between the extremes of pure helium and pure xenon,

quantify the variance possible among rods of contemporary design thate

have been fabricated and operated identically, and

provide instrumented, irradiated rads that are thoroughly characterized*

as to fabrication parameters and thermal history, for use in transienttesting under off-normal conditions.

2.1 CORRELATION WITH IFA-431/432

IFA-513 is very similar in design to IFA-431/432. All three assembliesconsist of six fuel rods in a hexagonal array, are of the same cladding stock,

and are well instrumented. However, a variety of fuel rod designs (differentfuel pellet dimensions, densities, and stabilities) were used in IFA-431/432,while the six rods in IFA-513 are identical except for fill gas compositionand pressure.

To provide a direct correlation between the three assemblies, rod 1 ofassemblies IFA-431/432 and rods 1, 3, and 5 of IFA-513 all have the same

fuel, 10% (235 ) enrichment, 100% helium atdesign:(a) 95% TD stable U0 02

o

(a) Except for length: IFA-431/432 has an ac.ive fuel length of 0.57 m, whileIFA-b13 has an active fuel length of 0.80 m.

1 atm, and 230 pm diametral gap. This design is considered to be the standardrod design for the test series and is based on the BWR-6 fuel rod design.Thus, besides providing a means to compare the assemblies, the standard rod

,

design provides results that may be directly applicable to power reactoroperation.

s

Several other factors also contribute to a good correlation between IFA-513and IFA-431/432. First, IFA-513 will operate at a peak linear heat rating ofapproximately 40 kW/m. This is midway between the peak powers of 33 and 49 kW/m

for IFA-431 and IFA-432, respectively. Secondly, the calibrations for all

three assemblies are done in the same manner, thus providing consistent esti-mates of power. Finally, even though the IFA-513 fuel pellets were fabricatedfrom a different powder batch, similar sintering conditions were used. The

resulting microstructure is quite similar to the fuel pellets in IFA-431/432.Therefore, IFA-513 fuel should behave in the same manner (see Section 4.2).

2.2 IFA-513 GAS MIXTURES

A variety of fill gas combinations are being used in IFA-513: four of therods use helium, while the other two rods use helium / xenon gas mixtures. The

current BWR design is used in rods 1, 3, and 5; this design includes fillingthe rods with pure helium at I atm pressure. Rod 2 is also filled with helium,but pressurized to 3 atm. This rod is included because new BWR rods may usethe higher pre-pressurization.

Rods 4 and 6 will provide data to improve the understanding of the thermaleffects of fill gas therral conductivity degradation. Both rods have an ini-tial pressure of 1 atm; rod 4 has an initial gas composition of 92% He/8% Xeand rod 6 has an initial composition of 77% He/23% Xe. These two mixtures pro-vide gas thermal conductivities that are approximately 75% and 50% of purehelium, respectively. Any differences in 80L behavior between these rods andthose that are filled with pure helium, may be directly attributable to thedifferent, and known, fill gas compositions. The well-characterized data -

obtained from these rods will further define thermal resistance behavior as afunction of power and gas mixture.

2.3 STATISTICAL ANALYSIS

Data from IFA-513 will be benefit in the evaluatinn of variaoility in fuel.

rod performance and any current bias between fuel rod behavior and computercode predictions. There are primarily two sources of variance in performance:because of manufacturing tolerances, identically designed fuel rods will not*

be truly identical; and there will be minor variations in the operating condi-tions from rod to rod (e.g., neutron flux tilt within an assembly). The finalresult for a particular fuel rod design, as illustrated in Figure 2.1, is adistribution of responses around a mean value. The three identical rods inIFA-513 will aid the evaluation of the amount of variability to be expected.

Evaluation of the bias between fuel rod performance and code predictionis more difficult. First, the distribution of fuel rod response must be known.

Next the rod design and operating conditions must be modeled and a predictedresponse, and attendant uncertainty, obtained.("} With these two pieces ofinformaticn, the amount of bias and the significance (b) of the bias can be

2.4 TRANSIENT TESTING

It is anticipated that some, or all, of the IFA-513 fuel rods will beused in the Power Burst Facility (PBF) for transient off-normal testing.These rods will be particularly useful because of their well-character _izedfabrication and operation. Since adequate instrumentation ;s an importantpart of any test, the IFA-513 rods are specially designed to allow disconnec-tion and reconnection of the thermocouple leads in order to obtain fuel temp-erature data during the PBF testing.

The PBF testing will consist of three phases: normal operation testingto evaluate the rods for effects of shipping on behavior, provide data forverification of the thermocouples, and provide general data to connect the PBFdata base and the Halden data base; off-normal testing to evaluate the effects =

of_ loss of coolant, power-cooling mismatch, reactivity insertion accidents,4

and/or other situations of interest; and finally postirradiation examination ,

to characterize the final state of the fuel rods and compare with similar' tests on unirradiated fuel rods.

3.0 IFA-513 DESIGN AND ASSEMBLY FABRICATION

The IFA-513 design is very similar to that of IFA-431/432. It will be-

discussed in three sections: the individual rod designs, the overall assemblydesign,(a) and fuel rod fabrication. The associated instrumentation will be,

discussed where appropriate throughout the report.

3.1 R0D DESIGN

All six rods in IFA-513 are nominally identical except for fill gas com-position and pressure. The cladding is annealed, seamless Zircaloy-2. The

fuel is compacted and sintered U0 . f 95% theoretical density enriched to2

23510 wt% 0. To reduce flux peaking at the ends of the fuel columns, a poi-

2 and 5% Dy2 3 is located at eachson pellet consisting of 95% natural U0 0

end. Table 3.1 lists rod design parameters; while Table 3.2 summarizes theas-built dimensions and variations. A general rod design schematic is shownin Figure 3.1. The pellet stacking order for each rod is in Appendix A.

The instrumentation for each rod consists of two thermocouples and a bel-lows-type pressure transducer. Because the thermocouples, W-3% Re/W-25% Re

with Be0 insulators, are located in the upper end (near the neutron flux peak)and the lower end of the fuel rods (see Figure 3.1), they provide temperaturemeasurements at two power levels, with the lower level approximately 70% thatof the upper. The pressure transducer is connected to the plenum and automat-ically provides continuous pressure measurements.

3.2 ASSEMBLY DESIGN

The complete IFA-513 assembly consists of the six fuel rods, additional,

instrumentation, and supporting hardware. Figure 2.2 is a schematic of thecomplete assembly. Figure 3.3, a core map of HBWR as of January 1979, showsthe location of IFA-513 (core position 3-5). Figure 3.4 shows how IFA-513 is"

oriented relative to the core center; all rods have orientation marks that faceoutward from the assembly center.

The assembly instrumentation consists of the following:

Cladding elongation detectors - Linear voltage differential transducers.

(LVDT's) are used to measure cladding axial elongation. The fuel rods arefixed at the top and allowed to elongate downward.

Self-powered neutron detectors (SPNDs) - Eight vanadium SPNDs and one.

cobalt SPND are used in this assembly. The vanadium SPNDs provide steady-

state flux monitoring and are used for calculating the local linear heatrate at the thermocouple positions. To determine the neutron flux profilethrough the assembly at the thermocouple positions, three detectors areplaced in each thermocouple plane. The detector centerlines are at thesame axial position as the thermocouple tips. The remaining two detectorsare located between the thermocouple planes and are in line with detectors1 and 6 located in the lower and upper planes, respectively. The cobalt

detector is used for monitoring rapid neutron flux changes and is locatedin the center of the assembly. The relationship between the thermo-

couples, neutron detectors, and reference axial neutron flux profile isshown_in Figure 3.5.

Inlet and outlet turbine velocity meters - These meters are used to mea-e;

sure the inlet and outlet fuel channel coolant flow rate during assembly

power calibration.

Inlet and outlet thermocouples - Chromel/alumel thermocouples with insu-.,

i lated junctions are used to measure the coolant temperature rise in the

fuel channel.i oI

3.3 FUEL R0D FABRICATION

Discussion of PNL's fabrication and characterization of the fuel pellets

used in IFA-513 appears in Section 4. Following fabrication, the fuel pelletswere shipped to Halden for assembly into completed fuel rods. Fuel rod fabri-cation and charact rization was carried out at the Institutt for Atomenergi'slaboratory in Kjel.er, Norway (Lunde, 1978).

The first step in the fuel rod fabrication process was to clean the fuel

pellets with alcohol then dry them in vacuum at 623K for 1 hr.

The Zry-2 tubing to be used as cladding was also characterized at thistime. A continuous monitoring air gauge was used to measure the inside diam-

0 Ueter of the tubes. Two linear traces at 0 and 90 and a spiral trace were,

taken. The equipment was calibrated with calibration rings and was found tohave an accuracy of 0.002 mm. Discrete measurements of the tubing outside

,

diameter were made by hand with a micrometer. The data froa both sets ofmeasurements is in Appendix B.

Assembly of the fuel rods began with the loading of the fuel and thermo-couples. During loading, the thermocouple tips were positioned as follows:lower thermocouples 80 mm above the lower end plug; upper thermocouples 118 mm*

below the upper end plug. After welding the lower end plug to the cladding,the plenum length was measured (Table 3.2), followed by insertion of the plenum

,

spring (Figure 3.7) and bearing disk. The next step was to weld on the upperend plug and bcllows pressure transducer assembly. The free volume within thefuel rod was then measured by a silicon oil manometer; the following are theresults of that measurement:

The sequence involved in completing the assembly of the fuel rods was to firstevacuate the rods, to refill them with the gas mixture chosen, and finally toweld shut the vent holes in the end plugs. The nominal gas compositions (involume percent) for the helium and xenon gases are as follows:

For rods 4 and 6 (92.3% He/7.7% Xe and 77%He/23%Xe), pressure was measured bymanometer to be 1.0 atm, with a maximum uncertainty of 0.1 atm. For rods 1,3, and 5 (100% He), pressure was judged to be 1 atm when glove box gloves*

showed no pressure differential (maximum uncertainty is 0.1 atm). Rod 2

(100% He, 3 atm) also has a 0.1 atm maximum pressure uncertainty.,

Electron beam welding in a vacuum ( 1.3 x 10-2 Pa) was used for all

welds except for those at the vent holes in the end plugs. The vent holeswere closed by tungsten inert gas (TIG) welding. Prior to welding, all

surfaces were cleaned with xylol (a) and alcohol.

After the fuel rod assembly was completed, the end plugs, seal welds, andthe active fuel length were x-ray inspected. No faults were found. The finalcheck of fuel rod integrity was for helium leakage. This was done using ahelium mass spectrometer with a sensitivity of 2 x 10-10 cm /s at STP; no3

leakage was found.

4.0 FUEL FABRICATION AND CHARACTERIZATION

This section provides a record of th'. fabrication and characterization of-

the fuel pellets used in IFA-513. Suhoection 4.1 covers the pellet fabrica-

tion process including acquisition of the U02 p wder, sinterability tests,,

pellet fabrication, pellet certification, and pellet physical measurements.Microstructural characterization of porosity and grain size is discussed insubsection 4.2. Thermal conductivity measurements are planned, but have notyet been performed.

4.1 FUEL FABRICATION

The fuel pellets for IFA-513 were fabricated from enriched UO ceramic-2

grade powder obtained from Oak Ridge National Laboratory (ORNL). This powder

was obtained under PNL purchase order 10990 AY and came from ORNL Mfg. Batch

No. 30-2785 (see Appendix C). When the powder was received, the containerswere inspected and net weights confirmed. The powder was then sampled and

analyzed, and the data provided by ORNL was confirmed. After the analytical

data was reviewed, a U0 Powder Certification of Compliance Quality Control2

Release was approved and the powder was released for pellet production(Appendix C).

Two sinterability tests were performed on the powder. The first, Test

No. 1556, was done on a 100g sample provided with the powder shipment. Pelletdensities greater than 95% TD were easily obtained and no need for specialprocedures was indicated. The second, Test No. 1559, was a pre-productionsinterability test to prcvide final parameters for pellet fabrication. Again,

the test was successful and provided the necessary information. The plans,

data, and conclusions for these two tests may be found in Appendix C. Also inAppendix C are the Pellet Fabrication Process Parameters that were used in thepellet production run.

*The specifications for the IFA-513 pellets, plus their required charac-

terization, are included in Table 4.1. The following outline is for the pro-cedure used to manufacture the fuel pellets:-

Before the pellets were final cleaned and shipped to Halden, all weresubjected to inspection and dimensional measurements were taken. All pelletswere checked for the following, and the data was recorded.

Visual Defects: The PNL visual standard for UO fuel pellets (shown in2

Figure 4.1) was used to visually inspect for chips and cracks.

Diameter: Measurements to the nearast 0.0001 in, were made at three

positions; near each end, and at the center. All pellets used in IFA-513met the specified tolerance of 0.0005 in.

Length: Each pellet was measured to the nearest 0.0001 in. at two

locations.

Weight: Each pellet weighed to the nearest 0.001 g.

Density: The geometric density for all pellets was determined from themeasured weight and average length and diameter for each pellet. .Thedensity of a selected number of pellets was also determined by a liquid

water was used as the suspension medium.(b) Theimersion technique:geometric densities are lower than the immersion densities. This isbecause the measured volume is not reduced to account for surfaceroughness and chips and is therefore greater than the true volume.

4.2 FUEL CHARACTERIZATION

Since the experimental data to be obtained from IFA-513 is to be correla-ted with data from IFA-431/432, it is important to understand the microstruc-

tural characteristics of the fuel. The fuel for IFA-513 was specified to besimilar to the 95% TD stable U0 fuel of IFA-431/432. However, it was fab-

2ricated from a different powder and sintered in a different furnace. The

i characterization plan was therefore aimed mainly at comparing the key micro-structural characteristics (pore volume, pore size distribution, and grain

size) of the.95% TD stable UO used in IFA-513 to that used in IFA-431/432.(a),

Pellet Characteristic Quality Control Specification (a) andor Attribute Inspection Results: *

Sunsnary Pellets numerically identified 1 to 520 were fabri-cated, pellets numbering 1 to 125 were drilled. Atotal of 18 pellets were rejected during inspection. ,

Of the total, 502 fuel pellets, 120 were dr111ed and382 were solid. Reject pellets were used foranalytical samples.

Visual Inspection All pellets were inspected in accordance with theChips & Cracks applicable PNL visual standard. NOTE: Although only

two pellets were rejected as a result of chips, aminor defect on approximately 30% of the pellets wascaused by a malfunction of the centerless grinder. Aslight flat was ground near the end of these pellets:in the extreme case 0.001 in, in depth and 1/8 in.in length and width. Rejection was not required forthis defect.

Pellet Diameter All pellets were inspected for conformance to the0.4205 1 0.0005 in. specification. The fulltolerance was observed: a few pellets had up to onehalf of the tolerance in the form of a slight taper.Most of the 18 rejects were due to undersized pellets.

Pellet length All pellets were inspected for conformance to the0.500 1 0.015 in. specification. The average lengthof all of the pellets was 0.497 in.: s95% of thetotal were within a range of 0.507 in. and 0.490 in.Five percent were in the range of 0.485 to 0.490 in.The two measurements taken 1800 apart on eachpellet did not vary more than 0.001 in.

Pellet Centerline 100% attribute go/no go inspection revealed theseHole centerline holes to be within the specified rar.ge of

0.067 in. to 0.071 in. An average hole diameter of0.070 in. was used for density calculations, however,a 0.070 gage would pass the center section of about50% of the pellets.

Experimental Procedure

The methods and procedures used to characterize the fuel pellets followed,

the same philosophy used for assemblies IFA-431/432 and reported in BNWL-1988.Measurements were taken to determine pore size and volume distribution, and

average grain size, as a function of radial location. No thermal resintering~

experiments were conducted since this fuel type was designed to be stable withregard to further densification.(a)

Based on experience with the fuel used in IFA-431/432, minor changes weremade in the testing and measurement procedures. Rather than providing a com-plete data reference base, this data is intended primarily as verification thatthe fuel pellets met their design criteria. Three pellets whose bulk densitymeasurements were approximately the average value for the pellets loaded in theassembly were selected from the assembly fuel lot. Each pellet was sectionedtransversely at its midpoint, encapsulated in epoxy resin, and polished by theprocedure described in BNWL-1988. Special care was taken to minimize physicalpullout of grains or UO particles. Light microscopy was used to examine the

2as-polished surfaces for pores larger than 2 um. Carefully controlled vacuum'

cathodic etching was then used to remove surface debris from submicron poros-ity. Smaller pores were examined by scanning electron microscopy at the samesites on the polished surfaces. Grain sizes were recorded on the same surfacesafter etching more vigorously (using H 0 -N SO ) to clearly reveal22 2 4grain boundaries.

The microscopy, porosity measurements, computation of porosity character-istics, and determination of grain size were all conducted as reported in

~

BNWL-1988. The following sites were specified for porosity study on each ofthe pellet sections: 2 peripheral, 2 mid-radius, and 1 center radial location.Data from all three pellets (15 sites total) was combined to obtain " average"properties. Grain size data was obtained from measurements made with photo-micrographs taken at a peripheral, mid-radius, and central area on each pellet.,

(a) The 95% TD stable fuel used in IFA-431/432 was found to be stable duringthermal resintering tests (BNWL-1988).*

Porosity Evaluation

The general pore size and volume distribution for IFA-513 (as sintered)is similar to that of IFA-431/432. The general nature of the porosity may be -

seen in the typical mictrostrutures shown in Figure 4.2. Table 4.4 and

Figure 4.3 provide an overall summary of the microstructures; the porosity,

normally varied randomly throughout the pellets within the ranges shown.

FIGURE 4.2. Microstructure of UO2 Fuel Pellets for IFA-513and IFA-431/432

IFA-513 and IFA-431/432 have similar porosity distributions, particularlyin the important size range of less than 10 pm diameter. -Both contain approx-imately 0.6 volume % of submicron porosity, and 4 volume % of 1-10 pm pores.'

IFA-513 appears to have about 1.5% more pores > 10 pm than IFA-431/432;

this larger volume may be related to the much smaller grain size present inIFA-513. The smaller grain size may lead to more intergranular porosity, andpossibly to more frequent pullout during section polishing. The greater total

pore volume measured for IFA-513 is primarily due to larger pores. This isreflected in the average values shown for the various size ranges in Table 4.4.The influence of porosity on the behavior of both IFA-b13 and IFA-431/432 isexpected to be essentially identical.

The pellets for IFA-513 were fabricated from the powder shown inFigure 4.4. Pretreatment of the as-received powder resulted in rounded agglo-

*merated particles averaging approximately 25-50 pm in diameter (upper photos

I in Figure 4.4). Close examination of the large particle structure reveals

!. that they are composed of close-packed, randomly shaped particles approxi-mately 0.1-0.2 pm in diameter (lower photos in Figure 4.4). This combination

of agglomerated particles permitted sintering to high density with some con-trol over retained porosity. No IFA-431/432 powder samples were available forcomparison.

j Figures 4.5 and 4.6 show details of IFA-513 pellet microstructure. Com-parison of average porosity at peripheral, mideadius, and central locations(Table 4.5,- Figure 4.7 and 4.8) would indicate a lack of significant differ-ences in as-fabricated pore dimensions, either within or between the IFA-513

and IFA-431/432 95% TD stable U02 pellets.

Grain Size Evaluation

A significant difference exists between the grain size characteristics* for'IFA-513 and IFA-431/432. As seen in Figure 4.9, the fuel pellets in

IFA-513 have a uniform grain size. These grains are approximately 12 pm in

diameter, with a maximum grain size of less than 20 pm. In contrast, IFA-431/I -

432 has a marked radial gradient in grain size, as shown in the figure. This

gradient varies from an average diameter of 22 um at the pellet periphery, toover 70 pm at the midradius and axis positions. The maximum grain diameter4

observed for the IFA-431/432 fuel was over 80 pm. The differences between

! IFA-513 and IFA-431/432 are further illustrated in Figure 4.10 and Table 4.6.The observed grain size differences can probably be explained by the variouscombinations of starting powder, furnace, and sintering conditions used forfabricating the pellets for the assemblies. The grain size for IFA-513, whilemuch smaller than IFA-431/432, is not likely to cause any densificationinstability (Freshley, et al., 1976).:

FIGURE 4.10. Summary of Radial Variation in Grain Sizefor IFA-513 and IFA-431/432

Conclusions

The fuel pellets used in IFA-513 and IFA-431/432 are similar in micro-structure. The greatest similarity is in porosity characteristics; the great-est difference is in grain size, where the grain sizes of IFA-431/432 are oftwo to five times larger than IFA-513. Based on the densification studies byFreshley et al., the combination of characteristics in both fuel batches (fewpores smaller than 1 pm diameter, total porosity of 5-7%, and grain sizegreater than 10 pm diameter) is expected to result in similar microstructuralbehavior, including densification stability.

.

5.0 ASSEMBLY OPERATIONa

During its irradiation, IFA-513 will be subjected to two operating condi-e

tions: the normal, steady-state operation of HBWR, and PNL-requested specialoperations. From the normal steady-state operation, the fuel rods are exposed

*\

to operating conditions that provide a standard data set of steady-state fuelcenterline temperatures, local linear heat rates, cladding axial elongation,and fuel rod internal gas pressure. The normal operating cycle for HBWR con-

sists of running at nearly full power for approximately two months, followed1

by shutdown for fuel assembly changes, maintenance, tad other necessary work.The special procedures are transient operations that take place within normalpower ranges. They are designed to provide additional data for the evaluationof fuel rod conditions.

5.1 STEADY-STATE OPERATION

At full reactor power, the peak local linear heat rate for IFA-513 is

approximately 40 kW/m. This is midway between the peak local linear heatrates of 33 and 49 kW/m for IFA-431 and IFA-432, respectively. An assembly

! average burnup of 690 - 1035 GJ/kgU (8 - 12 GWd/MTM) is currently planned.# In addition to being midway in power to IFA-431 and IFA-432, the selected

power level for IFA-513 is important for these reasons: First, experience at

Halden has indicated a threshold temperature for thermocouple failure. For

extended periods of operation, this threshold temperature is rpproximately1900-1950K. Therefore, it was recommended that IFA-513 temper 1tures be held

below 1775K where reasonable, to reduce the probability of th' mocouplefailure. Second, the 1775K temperature limit will prevent restr cturing ofthe fuel and corresponding changes in fuel properties.

At 40 kW/m, rods 1-5 are expected to have fuel centerline temperatures ofless than 1775K. However, rod 6 (77% He/23% Xe fill gas) may initially exceed

*1775K. Therefore, it is proposed that Halden initially limit the power in

IFA-513 (by appropriate control rod positioning) so that rod 6 will not exceedthe requested temperature limit. The power level for IFA-513 may be raiseda

after initial fuel relocation has reduced the thermal resistance of the fuelrods.

41

.

Data collection during steady-state operation occurs every 15 min and ishandled automatically by a process computer (IBM-1800). This data is storedon disk for 24 hr and then transferred to magnetic tape for permanent storage. '

5.2 SPECIAL OPERATIONS,

One result of the early analysis performed on IFA-431 and IFA-432 was

increasing needs for two types of data that had not been obtained during thenormal operation of HBWR. The first of these needs was an increase in the

amount and quality of low-power, steady-state data. Normally, low-power data,

is obtained only during rises to full power. However, only a few rises occurduring each operating cycle. In addition, the vanadium neutron detectors arenot completely stabilized under those conditions;(8) therefore the resultingpower estimates are biased in comparison to those that would be obtained undertrue steady-state conditions. The solution to this problem has been to use a" staircase" approach to power, as illustrated in Figure 5.la. By holding atthe intermediate power levels for 1-3 hours, both the amount and quality oflow-power, steady-state data is improved.

The second of these needs has arisen from efforts to better understand thebehavior of fuel rods. Theoretical considerations have shown that temperaturedata from power drops can be used to evaluate fuel rod thermal parameters andto verify thermocouple accuracy (Cunningham, Lanning and Montgomery, 1979;

Lanning, Barnes and Williford, 1979; Lanning and Cunningham, 1979). Afterreaching full power, two types of power drops are performed. The first is

called a " step" power drop: ideally an instantaneous 20% drop. Realistically,however, this cannot be obtained; therefore the requirements are a 20% drop inless than 15 sec (see Figure 5.lb). The data obtained from this operation isused to analyze fuel rod thermal parameters. After bringing the reactor backto full power, a linear power drop (20% in 30 sec) is performed. This data isused for thermocouple verification. Data from both power drops is collectedat 1 sec intervals. -

By performing a staircase power rise just prior to the power drops, animproved correlation may be made between the steady-state data and the tran-

I sient analysis. Preferably, the combined staircase and power-drop operations .

would be carried out once per month, depending on the reactor operationsschedule. However, this sequence is particularly important during the initial

,

startup of the assembly and during subsequent startups following extendedshutdowns.

Internal profilometry, prior to fuel loading, was performed by Kjeller.

| The equipment used was a continuous recording air gauge. Two linear traces,at 0 and 90 , were made (middle and lower curves in Figures B.1-B.6), and'

a spiral trace (upper curve in Figures B.1-B.6). The equipment was calibrated

with calibration rings and has an accuracy of 0.002 mm. Table B.i. coiltainsdiscrete cladding outer diameter measurements that were taken by tand.

SINTERABILITY TEST PLAN

h Prepared by N. C. Davis .Date 2-22-77/ 2 '- ''

Approved by O. W. Brite [k8]d Test No. 1556

.

I. Purpose of Test. The purpose of this test is to determine the process235parameters and sintering characteristics of the 10% U U0 btained

2for the-IFA 513 fuel pellet program. Specifically, a high density (95% TD)*

with a stable structure is required. Density and dimensional results willdetennine; process parameters, press tooling and the need for additionaltesting. Normal processing shall be followed to the extent possible with

this new lot of UO2 powder.

II. Reference Tests. There has not been any previous experience with this lotof 00 . The chemical and physical data furnished by the powder supplier is

2attached. The powder lot has been sampled for additional and confirmingdata to assure confonnance to specification p. ior to release for this IFA-513program.

The manufacturer's data, and the physical appearance of this powder indicates235

f a similarity to a lot of 93% U , UO2 p wder obtained from the same source,~

(Oak Ridge National Lab.). This powder was recently processed in Tests No.1551 and No.1552. Although this new lot of 10% powder has a higher specific

2 2surface area 6.63 M /gm as compared to 3.1 M /g for the 93% powder, thecoarse granule appearance of the two' powder lots is very much alike. In thereference test final density of only 92% was obtained, indicating specialprocessing, such as Ball Milling would be necessary to increase the. sinter-ability. This may not be the case with this 10% powder having the highersurface area and for the first test normal processing should be followed.

.

III. Material Recuirements. The sinterability sample of 100 grams provided bythe manufacturer, will be used in this test. Approximately 10 pellets canbe made with existing pellet press tooling.

.-

IV. Special Instructions.

To provide additional data on this powder lot, the tap density, and particle' size, sieve analysis should be obtained before proceeding with the following .

,.normal process steps.

|jfs EVALUATION OF SINTERABILITY TEST - 1556.

The first sinterability test (1556) of the 10% Enriched U02 powder for the IFA-513,

project was successful. The following observations and recommendations are basedon the test results and the proposed parameters for processing.

,

eNormal processing without any special powder pre-treatment is apparently*

adequate to produce sintered densities greater than 95% TD.

The pellets visual inspection indicated high quality without excessive cracks*

or chips. The appearance of the microstructure of a broken pellet showeduniform, apparently stable structure.

Recommend a pre-production test to conf.irm these results with an existing*

i die and flat faced punches, that wil1 produce dimensions within the specifi-,.

Samf e pellets should 'be drilled for the required-TC hole and' lcation limits.

variations should be made with the sterotex to reduce the density approximately

0.5%.

A final pre-production test should provide data for the processing parameters*

,

and limits needed to produce the pellets for the IFA-513 program.i

This test plan is being prepared and will be made on approval and Quality*

Control release of the powder lot.

.

I. Purpose of Test. The purpose of this test is to determine the final

fabrication parameters necessary to produce the 1FA513 fuel pellets.Previous tests will be refined using the correct tooling size toobtain the specified dimensions and density.

II. Reference Test. The previous sinterability Test No. 1556 will beconfirmed in this pre-production test. In the previous test, this

23510% U , Oak Ridge powder was determined to be highly sinterablewith normal processing.

III. Material Reouirements. In order to test this powder with two

amounts of sterutex, approximately 200 grams will. be required.

IV. Soecial Instructions. The previous sinterability Test 1556 pro-vided data on tap density and sieve analysis for this lot of U0

2powder. This test also indicated that normal processing shouldbe adequate for making production pellets. The following stepsshould be followed for this confirming pre-production test:

Granulate "as received" U0 to pass a 100 mesh screen.*

2

Slug the 200 grams of powder in two 100 gram increments,*

using the 2" die and s 5 ton pressure. This is an increasefrom the 3 tons used on the previous test which only yielded

3a slug density of 3.7 g/cm . Record slug size and density.* Granulate the slugs to -20 mesh and again split into two

100 gram increments.

* Blend 0.3 wt% sterotex with one increment and 0.4 into theother. *

.

EVALUATION OF PRE-PRODUCTION TEST 1559

.

The pre-production test (1559) of the 10% enriched UO f r the2

IFA-513 project was successful. Density and dimensional results pro-vide assurance that parameters can be established to fabricate theIFA-513 pellets. The following observations and connents are based onthe test results and the proposed parameters for processing:

A visual inspection of the pellets indicated good physical integ-*

grity. The cross section appearance of a fractured pellet showed'

uniform microstructure.

Normal processing without any special powder pre-treatment isapparantly adequate to achieve sintered densities of 95% orgreater. However, all the as received powder should be reducedthrough a 100 mesh screen to assure uniformity.

* The press tooling used in this test is satisfactory for the produc-tion of the 1FA-513 pellets. As pressed they are 0.541 inch diam-

3eter and if pressed to approximately 5.15 g/cm density and sin-tered 1700*C for 8 hours, they will reduce s 21.5% in both diam-eter and length. This will allow s 4 mils .to clean up the requireddiameter of 0.4205".

* The as pressed length should be held to 0.636 1 010 to maintainthe specified sintered length of 0.500'.

1

* The drill used for the TC hole #43 produced a final ID of 0.069which is within the specifications.

* Little diffe ence in thc final density was observed in the use of

0.3 or 0.4 wt% sterotex. It is difficult to obtain meaningful,

results in a small test; however, the larger amount of the pore-~

forming additive is recommended in this highly active powder..

Th_!

Extremely uniform distribution of this sterotex will be necessary tomaintain the 95 + 0.5% density specified.

s*

The process parameter sheet and density content charts are beingprepared for approval and release for production.

UO PELLET CERTIFICATION2a

Project IFA 513 Ealden Fuel Pellet Fabrication

'Pellet Lot No.1

Pellet Batch No.1

Applicable Specifications: ASTM Specification C776-76 and memo, C.R.Eannto D.W.Brite, February 17, 1977.

Review of Inspection Data

The fabrication impection and analytical data for this lot of pelletshave been reviewed ar uth the exception of EBC, they conform to theabove referenced specifications.

The EBC values calculated for three pellet samples from this lot were8.7, 8.8, and 8.8 ppa. The specification limit is /. ppm maximum. The reasonfor these high EEC values is believed to be current problems in achievingthe usual lov detection limits for Gd and S= of about 0.3 ppm. The detectionlimits reported for these samples for both Gd and Sm were 1.5 ppa. The EECvalues without Gd and Sm were 1.7,1.7, and 1.8 ppm. It has been estimatedthat even if the ESC is as great as 8.8 ppm, no significant effects on theirradiation experiment vill occur.
