1. INTRODUCTION l

Remote metrological and visual monde structive examinations were per-formed on 62 irradiated fuel and reflector elements removed from the High Tem-perature Gas Cooled Reactor (HIUR) core of the Fort St. Vrain (FSV) Nuclear Generating Station

following the January 1984 refueling operation. The l examinations of these core segment 3 elements were performed in the hot se r-j vice facility (HSF) at FSV from June 2 through June 23, 1984.

The standard fuel and reflector elements are 793 mm loss graphite bodies with a hexagonal cross section of 359 mm (across-the-flats) and a total weight of 128 kg (Figures 1-1 and 1-2). Examinations of these large irradiated elements were performed by a metrological robotic device and an experimental samma robotic device both developed by GA Technologies (GA) . The inspected elements isoladed all 42 fuel elements and 9 reflectors elements from region 18, a side reflector and 4 fuel elements including FTE-2 from region 22, a fuel element from region 3, 2 reflector elements and 3 fuel elements from region 13. All of the selected elements from regions 13 and 3, and 2 of the selected elements from region 22 were surveillance elements.

Survellianos elements, easily recognized by the fidseial holes drilled la their oormers, were extensively characterized prior to insertion into the core (Ref. 1).

The mondestructive examination laoladed the followlag:

1. Dimensional measurements (all fuel elements, selected reflector ele-meats) on the following:

The Fort St. Vrain Nuclear Gomeration Station is owned and operated by the Public Service Company of Colorado (PSC).

b. Length

c. Coolant hole, diameters

d. Distances between coolant holes

e. Distances between fiducial boles (surveillance elements and FIE-2 only)

f. Bow

2. Gross samma activity (selected elements) and aestron activity (selected elements) measurements.

3. Visual laspections (all elements) for the following:

O a. Cracks

b. Graphite oxidation

c. Amy other structural damage (chips, scrathces, etc.)

. d. Evidence of mechanloal interaction between elements

e. Other features of interest (discolorations, corrosion, flow marks, etc.)

4. Fission product isotopic distributions (selected elements)

(NOM: This data will be reported la early 1985) .

l Table 1-1 sammarises the surveillance of FSV core segment 3.

l These mondestructive examinations were performed mader the FSV Fuel Surveillance Program sponsored by the Department of Energy (DOE). Previously, l 51 fuel and reflector elements from core segment 1 were similarly examined in l July 1979 (Ref. 2), and fif ty-four feel and reflector elements from core ses- i meat 2 were inspected in April 1982 (Ref. 3).

2. IRRADIATION CONDITIONS The time-and-volume-averaged graphite calculated (via the SURVEY code) irradiation temperatures for the core segment 3 fuel elements examined in the HSF at FSV ranged from 3800C to 6700C at the element midplane. The fast neutron fluences ranged from approximately 0.96 to 2.82 x 1025 n/m2 (E > 29 fJ) HTUR.

The following HTUR codes were used to simulate the irradiation condi-tions:

o GAUGE (Ref. 4) . A two-dimensional, four group neutron diffusion and core depletion code. GAUGE treats the core as a single layer and calculates nuclide densities as a function of time and radial core location.

o PEVER (Ref. 5). A one-dimensional, multigroup neutron diffusion and de-pletion program for calculating nuclide densities as a function of axial core location.

o BUG-2 (Ref. 6). A two-dimensional, multigroup neutron diffusion and de-pletion program for calculating nuclide densities as a function of axial core location for fuel assemblies influenced by partially inserted con-trol rods.

. o SURVEY. A computer program for the thermal and fuel performance analysis of fuel elements. The code performs coarse mesh survey analyses for 1

large numbers of spatial positions, calculating a time history of the irradiation conditions and fuel performance for each space point. SURVEY calculations are based on radial power distributions obtained from GAUGE and axial power distribution obtained from FEVER and BUG-2.

However, because of the numerous changes in power during cycles 1, 2, and 3, a simulation of the ac-taal reactor operating history would be prohibitively expensive. Consequent-ly, . the reactor power history for the cycles was represented by 651 time in-tervals of approximately uniform power. Cycle s 1, 2, and 3 were simulated with the GAUGE code using this detailed power history. A SURVEY analysis of the segment 3 elements was then performed based on the GAUGE results. The I number of time intervals was further reduced from 651 to 100 for this anal-ysis. Figure 2-1 shows the reactor power history used for the SURVEY anal-ysis. The time- and volume-averaged graphite irradiation temperatures for the segment 3 elements were obtained from the SURVEY code results.

The temperature uncertainty is primarily due to the uncertainty in the power. Based on the results of nuclear and thermal design verification studies performed with data from the Peach Botton HTUR (Ref. 7), the uncer-tainty in the power (and fast neutron fluence) calculated for a given core location is ~_+10% (la). The uncertainty for a given temperature is therefore approximately 10% of the difference between the calculated temperature and the gas inlet temperature (~3350C, time averased) .

3. MTROLOGICAL EXAMINATIONS Metrological examinations were performed on 55 of the 62 elements in-f spected. Seven reflector elements from region 18 were not measured but were examined visually. The dimensional measurements were performed in the HSF at FSV with the GA metrology robot. The strains and bow data obtained from these messarements were compared with the H1UR design code strain and bow predic-j tions.

1 1 i 3.1 Descriotion of Metroloav Robot System

! The metrology robot (Figure 3-1) consists of a structural frame, rotary table, probe, and instrumentation. Irradiated core components are placed on the rotary table by the FSV fuel handling machine. The rotary table permits

) all polats on the top and sides of a component to be positioned within the i

operating range of the probe. The two-finger probe (Figure 3-2) moves in the 1x, iy, and is directions (Fig. 3-3) . Upon contact with the test object, the I

probe head undergoes a displacement which activates a microswitch and termi-nates probe movement. The probe head has a primary and backup microswitch for each direction of displacement (1x, ty, is).

Programmable stepping motors power the four drive systems of the robot.

The stepping motors are coupled with free-wheeling d.c. motors which serve as anziliary drive sy s tems. The motor drives are modularized for quick replace-l l meat. Each full motor step is equivalent to 0.025 mm (0.001 in.) movement in

! the z and y directions, 0.032 mm (0.00125 in.) la the a direction, and 0.03-degree rotation. The coordinates of a palat on the surface of an element are j determined by remains the probe into the element and recordlag the position and displacement of the probe. Massatio encoders (Sony Magno scale s) and O rotary potentiometers (backup) measure the position of the probe.

! controls the robot and processes the data. A set of custos designed and f ab- ;

1 l 4

ricated circuit cards collects the raw data from the instrumentation systems i

of the robot. He cards are wired directly to the computer memory system so

} that a simple program sabroutine can collect the robot data la a very short +

time (~1 millisecond) and deposit it directly into main memory. This more efficient method of data collection and transmissica reduced the time for a fall length inspe ction (approximately 600 data points) from 4-1/2 to 2-1/2

hours.

1 I The robot ope rate s la a fully automated, closed-loop mode. This la-clades computer verification of proper movement and corrective actions without l any, or mialmen, operator laterface. Comparison of redundant measurement de-t l vices, as well as on-line data reduction, is done by the computer. This l allows the sy stem to automatically overcome potential malfunctions, such as

motor stalling or missing an intended hole or surface. System redandancy is used to maainize data output and minimize downtime.

3.2 Descrintion of Metroloalcal Examination The dimensional examination of an irradiated fuel or reflector element may consist of up to five type s of measurements. The measurement type and order of performance (if selected) are as follows:

l' The measurement sequence and length of inspection are selective. The side face, top surface, and coolant hole measurements have both in11 length and abbreviated versions. The fall length versions are need for the surveil-lance and test elements. The abbreviated version is generally used for all other elements. The abbreviated version is shorter by approximately one hour.

3.4 Resnits of Metrolony Robot Fifty-one H-327 graphite and one H-451 graphite fuel elements were metrologically examined. An infrared thermometer temperature gas was setup to perform the surface temperature measurements: however, it failed af ter eight inspe ct ions. A resistivity thermometer device located on the probe was them used to measure the surface temperstares. The measured element surface temperatures ranged from 330C to 480C. The metrological resnits along with the calculated results are presented in Tables 3-1 and 3-2. The core segment O 3 maximum element average shrinkages in length and across-the-flats dimensions were 5.80 mm (0.23 in.) sad 2.05 mm (0.08 in.), respectively. The maximum observed bow (see Fig. 3-9) was 0.69 mm (0.027 in.). The axial and radial dimensions of nearly all of the fuel elements shrank as a resnit of the irre-diation. One H-327 graphite fuel element expanded siishtly 0.03 mm (0.001 in.) across-the-flats (radial). This element was located la region 18 core

layer 9. This phenomena was also noted in the core segment 2 surveillance where one fuel element and a side reflector also expanded slightly in the radial direction (Ref. 3). The core 2 fuel element was also located one layer i

j above the reflector elements (layer 9) . No core segment 3 fuel elements ex-l panded axially. However, there was measured axial expansion in the examined I

i reflectors (one top, one side and one bottom) . The maximum expansion measured f was 0.48 mm (0.02 in.) in the bottom reflector.

All of the fuel elements la region 18 were f acinded in the core 3 sur-a j veillanee. Figure 3-10 shows the axial strain and bow distributions measured

! for these fuel elements. The latra-element axial strains tended to be lower on the E isee side and on the sides adjacent to the E face, the F and D f aces.

The bow and axial strains in the other exam-imod regions did not follow these trends. See Figures 3-11, 3-12, and 3-13.

The radial strains tended to peak la core layer 5. This was also true of the l axial strains. Figures 3-14, 3-15, and 3-16 show the intra-element measured radial strain for region 18, 22, and 13 and 3, respectively.

Bach core surveillance provide additional in pile data. These data are used to gain a better perspective of the range of potential strains la H1GR fuel elements *. The fast neutron doses received by the core segment 3 ele-l

meats [<2.8 x 1025 m/m2 (E < 29 fJ)RIUR] were less than the expected lifetime doses that would be received by most fuel elements in a E1UR. Since the fast fluences were low, the measured strains were relatively small ((1.0%) . Fig-ares 3-17 and 3-18 show the envelopes of measured strains for core segments 1, l 2 and 3 surveillances as compared to the range of potential strains using the l

H-327 graphite design curves.

3.5 connarisons of Measured ==A caloalated Strains and Bow Strain and bow predictions were obtained using the SURVEY / STRESS (Ref.

9) code. SURVEY / STRESS calculates stresses, strains and deformations (bow) in an E1UR fuel element based on viscoelastic beam theory. It is the simplest and most officient of three code s used to caloalate stresses in H1UR fuel elements. It is used to survey the entire core to identify potential critical elements which eam be further studied by more refined analysis. Since SURVET/ STRESS models all the important physical effects and structural

The measured strains (AL/L) facinde the creep strain and elastic strain as well as the irradiation-indsoed strain. However, the creep strain and elas-tio strain for these elements were small, so the measured strain is approzi-l mately egaal to the irradiation-indsoed strain (at room temperature).

a. The calculated axial strains were consistently lower for all ten-perature and fluence ranges. The disagreement between measured and calculated strains increased with higher fast fluences.

b. The agreement between measured and calculated axial strain was within the 10.0001 mm/mm to 0.002 mm/mm range for fluences lower 25 Whereas, the agreement between measured and than 2.0 x 10 m/m2 calculated axial strain for fluences greater than 2.0 x 10 25 n/m2 ranged from 0.002 mm/s to 0.0045 medse.

2. Radial Strain

a. The calculated radial strains were consisM atly lower than the measured straina.

b. The agreement be tween calculated and measured strains was within 10.003 mm/mm for all elements.

c. The agreement between calculated and measured strains varied with fast fluence. The lower the fast finance the better the agreement.

N/C I I The polynomial expression used la SURVEY /SHESS code to represent the design data for irradiation-induced dimensional change of E-327 graphite has been revised (Ref. 10) since the core segment 2 surveillance. The revised polynomial expression no longer exaggerates the rate at which the H-327 graph-

3.6 FM-2 Metrolomical Results i FTE-2 underwent very little dimensional change as a result of irradia-tica. The element average axial and radial strains were measured to be

-0.262% (0.9 mm shrinkage) and -0.099% (0.4 am shrinkage), respectively. The I maximum bow was 0.10 mm. The radial and axial strala distributions, (from l across-flats dimension and element length messarements), for F11-2 are shown l

l in Figures 3-11 and 3-15. The maximum bow for each side face is also shown la Figure 3-11.

The measured strains were compared with the calculated strains (via the SURVEY /SHESS code) . The differences between calculated and messared axial and radial stratas weice -0.013% and -0.112%, respectively (see Tables 3-1 and 3-2). The polynomial expression used in SURVEY / STRESS to represent the design data for irradiation-induced dimensional change of H-451 graphite slightly overpredicted the stralas (see Tables 3-1 and 3-2) .

4. GAIGIA AND NEUIRON ACTIVITY MEASUREMENTS 4.1 Gamma Dose Rates Gamma dose rates at 91 cm (3 f t) and at 100 cm (39.5 in.) were measured for selected segment 2 elements with a Reuter-Stokes, Model RS-C4-1606-203, samma ionization chamber.

Figure 4-1 shows the geometry for the samma dose rate measurements.

The PATH (Ref.11) gamma shielding code was used to calculate the gamma l dose rate at the above specified distances. The PATE analysis calculated nuclide densities of the major gamma contributors. Dose rates calculated by the PATH model were then scaled according to the nuclide densities of the major gamma contributors to give the calculated dose rate for each fuel ele-ment.

Table 4-1 shows the results of the measured and calculated gamma dose rates. The measured gamma dose rate for a top reflector was 76 mR/h. The nearared samma dose rate for fuel elements ranged from 605 to 2815 R/h. The ratio of calculated to measured samma dose rate for examined fuel elements ranged from 0.78 to 2.11 with an average of 1.04. If the worst case ratio of 2.11 is omitted (see Table 4-1), the average ratio of calentated to measured gamma dose rate is 0.99. The previous surveillance (Ref. 3) had an average calculated to measured gamma dose rate of 1.7. The better agreement for the ccre 3 segment can be attributed to more precise source terms used in the PATE calculations.

l 4.2 Neutron Count Rates Neutron count rates for selected segment 3 fuel elements were measured using a SNOOPY-type detector system equipped with a Reuter-Stokes, model RS- -

The measured counts are not believed to be cor-rect because the detector indicated higher counting rates for the background than for a fuel element. The system is believed to have degraded due to elec-tronic noise. Therefore, the neutron counts will not be presented in this report.

5. VISUAL EIANINATION The visual examinations were performed concurrently with the metrologi-cal examination. A core component (element) was lower into the HSF by the fuel handling machine (FHN). The element was placed on the turntable of the metrology robot. During the metrological examination, the turntable rotated the element so that each side face (Fig. 1-2) could be viewed through the HSF window and by the camera system.

l The 62 segment 3 fuel and reflector elements were visually examined using four remotely controlled television cameras equipped with pan / tilt units and zoom lenses. Lighting was provided by the HSF lighting, by remotely con-trolled camera lights, and by three light banks. All surfaces of each element ,

4 were thoroughly inspected and recorded on videotape. In addition the element side faces were photographed through the HSF window with a 35-am camera equip-pod with a telephoto lens. Two photographs (the top half and bottom half) of each face were taken to give a composite picture of the entire face. Polaroid photographs were taken from the television monitors of features of interest.

The visual examinations were hampered by numerous camera and peripheral equipment malfunctions resniting from the high dose rates (12900 R/h at 1 meter). The dose rate for segment 2 elements 1500 R/h at 1 meter. However, all 62 elements were videotaped.

The inspected elements were in good condition. No cracks were detec-ted. Three dowel pins on an element were damaged. Another element had ex-terior damage in one dowel socket. Little evidence was observed of graphite oxidation or erosion. Most blemishes observed on the elements were typical strains of scratches, scrapes, rub marks, interface marks and flow marks (Fig.

! 5-1). These were similar to the observations of the first two segments (Ref s.

2 and 3) and of the inspection of core region 35 in March of 1979 (Ref.12) .

i The results of the visual examinations of the regular and surveillance fuel l

and reflector elements are discussed in more detail below. The fuel test element, FTE-2, is also discussed below in a separate subsection.

! 5.1 Reaular and Surveillance Elements Visual Results i

The regular and surveillance fuel and reflector elements were fabrica-ted from H-327 graphite. The observed blemishes are discussed below.

t 5.1.1 31ging

O Dark stains were observed on many side faces of the elements. However, stains were seen most frequently on the control rod elements (column 1) and on the E face of elements (Fig. 5-2). The E face was always toward the control column. The general appearance of a typical stain was as if liquid had trickled down the element face leaving a dark residue. In general, there was no consistent staining pattern. Some stains were very prominent others were barely visible. Some stains could be traced down a column, while others started or ended abruptly. The paths of a few stains were disrupted by the top edge of the adjacent element leaning against it which caused the staining liquid to run horizontally and disperse or continue downward at an offset (Fig. 5-3).

Similar stains were observed on the fuel and reflector siements during previous inspe ctions. During the inspection of region 35 (Ref.12), samples

! of the staining material were collected and subjected to gamma spectroscopic analysis. A high concentration of iron and silicon and lesser amounts of lO I

The presence of iron may have come from the unplanned water ingresses into the prestressed concrete reactor vessel (PCRV). The silicon and aluminum are believed to have come from the Knowool insulation used in the core. The copper apparently came from alloys used for reactor or water system components. These material were apparently carried down the elements by the water, and was lef t behind as a residue.

Figure 5-4 shows arother observed stain. These localized stains were seen on several elements. The appearance is circular with a darker central area which may contain contaminants.

5.1.2 Scratches and Scranes O Numerous scratches and scrapes were observed on the surf aces of many of the elements. Most of these markings were insignificants however, some are notable and are listed below.

oA continuous (sometimes discontinuous) vertical scratch of some depth down the center of face C of an element (Fig. 5-5).

Four of the core segment 3 elements were observed to have this scratch.

This scratch was also noted during the previous two inspections, but is not believed to be of a depth to cause any structural problems.

o Vertical scrapes and scratches on the left and/or right sides of face D of the element (Fiss. 5-6).

This type of marking varied in length and degree of scraping and scratch-ing. Some elements only had a scrape or scratch for only a few vertical inches on the left or right side, while other had marking extending the length of the block. Forty-five elements were observed to exhibit these Page 64

O TITt2: NONDESTRUCTIVE EIANINATION OF 62 FUEL AND REFLECIVR ELEMENTS FROM FORT ST. VRAIN CORE SEGMENT 3 lDOCUIRIrr NO. 907785 lISSEE NO./LTE. N/C l 1 markings on face D. Elements from the segment 2 surveillance were ob-served to have similst markings.

o Vertical scratch on right and/or left side on f ace F of an element (Fig.

5-7).

Twenty one segment 3 elements exhibited this scratch on the right and some time left side of face F. This particular marking was noted only on one element during a previous surveillance.

Since the above mentioned scratches and/or scrapes were nearly identi-cal in location and appearance, they are believed to have been made during handling and are not believed to be of sufficient consequence to cause any future structural problems.

l 5.1.3 0xidation Iron, which is a catalyst for graphite oxidation, was found on the residue of the evaporated stains (see Section 5.1.1) . This suggests that f oxidation may have occurred due to contamination by iron which seeped into the graphits. Therefore, darkened areas in the vicinity of stains or on control elements and face E of regular elements are possible sites for localized graphite oxidation. Figures (5-8, 9) show two suspicious darken areas which may have a little oxidation.

5.1.4 Rub Marks l

l Light vertical bands and/or columns of short, horizontal marks were l

l observed near the left and/or right edge s on some side faces (Fig. 5-10).

l Twenty of the examined elements showed this type of burnishing indicating some Page 65 i

The rubbing highlighted the machining marks on the side faces, but did not removed them. Since the degree of abrasion appears to be about the same as observed in surveillances 1 and 2, the ob-served rub marks probably are the results of earlier core movement (Ref. 2, 3 and 12). This observation represents evidence that the core restraint devices installed at the start of cycle 3 were effective in reducing fuel element movement.

5.1.5 Flow Marks Dark horizontal bands, approximately 45 mm wide, were observed on near-ly all faces of the control-rod elements (Fig. 5-11) and on face E of the regular fuel elements (Fig. 5-12). Face E of the regular elements always f aced the column of control-rod elements. In the FSV core, the control-rod columns are vertically offset from the surrounding columns of regular fuel elements by one quarter of a block length. The dark bands appeared at the axial locations corresponding to the top and bottom chaefers of the adjacent fuel elements. Two chaefers are a total of 45 mm wide, the same width as the 1

! dark bands.

l The dark appearance of these areas is indicative of surface roughening l

due to graphite erosion caused by particulates in the coolant flowing through the flow paths formed by the sides of elements and the top and bottom chaefers l of the adjacent elements. The horizontal displacement of stains (Subsection j 5.1.1) at these block interfaces suggests that substantial coolant flowed through these flow paths. On several blocks, there were dark areas above or i below the dark bands (Fig. 5-13). These are thought to have been soot depos-its formed by the graphite abraded from the elements.

Nicks and Debris There were a few small nicks and chips on the elements. Most of these were very minor and insignificant. However, element serial number 1-1228 (core location 18.03.F.06) had minor damage to all three of its dowel pins.

The two E face dowel pins were more chipped than the B face dowel pin. Figure 5-14 shows the damage to the E face dowel pins. The elements located above and below this element appeared to be free of dowel pin or socket damage.

Element serial number 2-1707 (core location 18.01.F.03) had damage to the B face dowel socket. A small chip of the graphite web between the dowel socket and the central coolant hole (319) on the B face edge was missing (Fig.

5-15). The element located above this element appeared to be free of dowel socke t damage. The element located directly below element 2-1707 had debris around both E f ace dowel pins, but was free of debris near the B face dowel pin (Fig. 5-16). This indicates that probably all three dowel socke t s of element 2-1707 had minor scaping and chipping. Since only the exterior of the E face dowel sockets of element 2-1707 could be viewed with the failing camera system, only the damage to the B face socke t was observed.

l i A few dowel pins also had wear debris, which came to rest on the top of the dowels (Fig. 5-17). Apparently, material was shaved of f dowel sockets in the bottom of one element by the dowel pins on the top of an element stacked below, and the shavings tended to accumulate on the upper dowel pin surf ace.

were cured-in-bed, the fuel rods in FTE-2 were cured-in place. Also, FTE-2 was fabricated from near isotropic H-451 grade graphite instead of the needle-coke H-327 grade graphite used in the initial core elements. Elements fabri-

cated from H-451 grade graphite are designated for FSV refueling segments and advanced HTUR designs. The visual examinations cf the test elements provide observable and concrete evidence of the H-451 graphite structural integrity i and performance.

FTE-2 was in excellent condition. There were small scratches but no significant structural damage. No cracks were observed on any of the sur-faces. There was no evidence of graphite oxidation.

The side faces of FTE-2 are shown in Figures 5-18 through 5-23. There was a discontianots vertical scratch running nearly the length of face C (Fig.

} 5-20). Face D had vertical scrapes and scratches on the lef t side (Fig. 5-21). The upper right side of face F also had vertical scratches (Fig. 5-23).

Siellar markings were observed on the regular FSV elements during this and previous surveillances, and are believed to have been caused during handling.

l l The photographs and video tape of some of the side faces had darkened areas which had the appearance of build-up of some substance (Figs. 5-20, 21, 22, 23). However, the darkened areas disappeared when the element was f rotated. A possible explanation is that particulate matter from the coolant flow or outgassing from the care-in-place caused a change in the surface finish which altered the reflectivity. Some of the darkened areas on the E I face did not disappear upon rotation and are thought to have been soot dep-osits formed by the graphite abraded from the elements (Fig. 5-22) .

5-25) were seen on this surface. The se markings were located around fuel

+

holes, coolant and adjacent barnable poison holes. These markings also were observed in FTE-1 where it was demonstrated that the darkened areas were not build-up of substances, but most probably stains caused by outgassing from the graphite cement used to cement the fuel hole plugs in place (Ref.14) .

None of the observed regular FSV elements showed these types of markings.

l The bottom surf ace of FTE-2 was in excellent condition and was relativ-ely free of blemishes.

SUMMARY

AND CONCLUSIONS f Sixty-two fuel and reflector elements from FSV core segment 3 were non-destructively examined in the HSF at FSV during June, 1984. These examina-tions were performed by GA at FSV as part of the DOE-sponsored surveillance program. The time- and volume-averaged graphite irradiation temperatures and volume-averaged f ast neutron finences for the elements ranged from approxi-mately 3800 to 670'JC and from 0.96 to 2.82 x 1025 n/ m2, respectively. The examinations were intended to verify the structural integrity and dimensional stability of the elements and to obtain dimensional change data and samma dose rates to verify HItiR design code calculations. The results and conclusions of the nonde structive examinations are summarized below. 6.1 Core Connonent Performance .

The axial and radial dimensions of nearly all the inspected H-327 graphite fuel elements shrank as a result of irradiation, but the dimensional changes were relatively small. The maximum element-average axial (AZ/Z) and

, radial (AX/I) strains were -0.73% and -0.57%, respectively. The maximum bow was 0.69 mm. The examined reflector elements underwent very little dimen-sional expansion (less than 10.48 mm) . The measured strains in segment 3 ele-ments were reasonably close to or greater than the calculated dimensional change s. The measured bow was consistently higher than the calculated bow. The visral examinations of the elements showed the elements to be in good condition. No cracks were observed. There was little evidence of graph-its oxidation. The evidence of mechanical interactions (rub marks) was no Page 95

N/C l l more severe than in the two previous surveillances which suggested that the core movement was very minimal or had stopped. Minor dowel pin and dowel socket damage was observed on two elements, but the damaged arets did not af-fect the handling, storage nor core performance of the elements. A few chips, nicks and other handling scratches were noted, but these blemishes did not af fect the performance of the core components. 6.2 Code Verification Strain calculations were performed with the H1UR code SURVEY / STRESS and the re sul t s compared with measured strains. The results of the comparison showed the calculated (SURVEY / STRESS) strains to be underpredicted in almost every case. The differences between the calculated and measured axial strains were less than 0.16% for fast fluences less than or equal to 2.0 x 10 25 n/m2 For fast fluence greater than 2.0 x 1025 n/m2 the maximum difference was 0.45%. The differences between calculated and measured radial strains were 0.12% and 0.34% for less than and greater than 2.0 x 1025 n/m2, respectively. The polynomial expression for the H-327 graphite irradiation induced strain calculations models the strains better at lower fluences. The measured bow was consistently higher than the SURVEY / STRESS calculated values. Gamma dose rates were calculated with the gamma shielding code PATH and compared with measured dose rates. The maximum measured dose rate at a dis-tance of 36.0 inches (91 cm) for the examined elements was 2815 R/h. The cal-culated to measured ratio for gamma dose rate ranged from 0.78 to 2.11 with an average ratio of 1.04. If the worst case of 2.11 is omitted, the range is from 0.78 to 1.33 with an average of 0.99. These results are considered to be quite good for gamma dose rate calcriations. O Page 96

There were small scratches, but no significant structural damage.                                             A few darkened areas were observed on the top surface, but these discolorations were not considered significant.                     No cracks were observed on any of the surfaces.                                There was no evidence of graphite oxidation.

The measured strains were slightly lower than the calculated strains. The differences between the calculated and measured axial and radial strains were -0.018% and -0.112%, re spect ively.

N/C 4 I l APPENDIX A METROLOGY ROBOT CALIBRATION i Eight full-length inspections of calibration element 8-0182* were per-formed prior to shipping the metrology robot to FSV for the surveillance of core segment 3. The accuracies of the robot measurements were determined and found to satisfy the accuracy requirements specifled in Ref. 8 (Table A-1). The results were reviewed and approved by GA Quality Assurance (QA). Quality Assurance approval of these results constituted QA acceptance of the metrology 4 robot for shipment to FSV (Table A-1). Five more inspections of calibration element 8-0182* were performed at FSV prior to the inspection of the first irradiated element. The results of the first four of these inspections (Table A-2) demonstrated that the quality of the robot measurements had not deteriorated after shipping and established the measurement biases to be used in processing the robot measurement da ta into fuel or reflector block dimensions. Run 5 included the biases and was used to verify calibration runs 1 through 4 (Table A-3) . The robot calibra-tion procedure (Ref. 8) specifies that a final inspection of calibration element 8-0182 be performed af ter the last irradiated element of a surveil-lance campaign has been examined, this was done and the results are in Table A-4. !

Element 8-0182 is a fully-machined graphite fuel element on which quality

! control measurements, corresponding to those performed on irradiated core components by the metrology robot, have been performed using calibrated mes-surement equipment traceable to the National Bureau of Standards. GA Quality Assurance has certified element 8-0182 as a special calibration standard for the metrology robot. O , Page 101
