INTRODUCTION This report presents the results of the examinations of Capsule T-330, a thermal surveillance capsule, and Capsule W-290, an irradiated surveillance capsule, removed from the Palisades reactor vessel during a Fall of 1983 outage. Throughout the operating life of the Palisades Nuclear Plant the thermal capsule, Capsule T-330, was located above the reactor core and was exposed only to the elevated temperature of reactor operation. Capsule W-290, the second irradiated surveillance capsule to be removed from the Palisades reactor vessel, is part of the continuing program which monitors the effects of neutron irradiation, on the encapsuiated materials, under actual operation conditions.

The Palisades nuclear reactor is a pressurized water reactor built by Combustion Engineering Inc.

The surveillance program for the reactor pressure vessel was designed by Combustion Engineering Inc. to the requirements of ASTM E185-66. A complete description of the surveillance program has been reported by Combustion Engineering Inc.[1]

This report summarizes the testing of and postirradiation data obtained from Capsules T-330 and W-290 removed from the Palisades reacter vessel, and discusses the analysis of these data.

The data are compared to the results of tests performed on unirradiated material E

as reported by Battelle Columbus Laboratories r'

SECTION 3 BACKGROUND m

n I

g The ability of the large steel pressure vessel containing the reactor core and its primary coolant to resist fracture constitutes an important factor in

{

ensuring safety in the nuclear industry.

The beltline region of the reactor pressure vessel is the most critical region of the vessel because it is subjected to significant fast neutron bombardment.

The overall effects of fast neutron irradiation on the mechanical properties of low alloy ferritic pressure vessel steels such as SA-302 (Modified) Grade B (base mate-ial of the Palisades reactor pressure vessel beltline) are well documented in the f

literature. Generally, low alloy ferritic materials show an increase in hardness and ten;ile properties and a decrease in ductility and teughness under certain conditions of irradiation.

E-A method for performing analyses to guard against fast fracture in reactor 7

pressure vessels has been presented in " Protection Again e Non-ductile

{

Failure," Appendix G to Section III of the ASME Boiler and Pressure Vessel

[

Code.

The method utilizes fracture mechanics concepts and is based on the reference nil-ductility temperature, RT I

NDT*

The initial RT is defined as the greater of either the drop weight NDT E

ni,-ductility transition temperature (NDTT per ASTM E-208) or the temperature I

60 F less than the 50 ft lb (and 35-mil lateral expansion) temperature as

]

l determined from Charpy specimens oriented normal (transverse) to the major working direction of the material.

The RT f a given material is used to NDT f

index that material to a reference stress intensity factor curve (K7p curve) f which appears in Appendix G of the ASME Code. The K curve is a lower IR i

^

bound of dynamic, crack arrest, and static fracture toughness results obtained from several heats of pressure vessel steel. When a given material is indexed l

to the K curve, allowable stress intensity factors can be obtained for

-- 'j p

yp this material as a function of temperature.

Allowable operating limits car then be determined utilizing these allowable stress intensity factors, y

'RT for. radiation embrittlement. -This-adjusted RTNDT (RTNDT NDT ARTNDT) is used~to indek the material to the KIR curve and, in turn, to set operating limits for the nuclear power plant which take into account the effects of irradiation on the reactor vesse' materials. _ RT can also be NDT adjusted by using radiation damage trend curves such as those identified in'-

NRC Regulatory Guide 1.99 Revision 1.

SECTION 4 DESCRIPTION OF PROGRAM Eight surveillance capsules for monitoring the effects of neutron exposure on the Palisades reactor pressure vessel core region material were inserted in the reactor vessel prior to initial plant startup.

Six of these capsules were positioned on the inner wall of the reactor vessel (" wall" capsules), while the other two capsules were positioned closer to the core, on the outer wall of the core support barrel (" accelerated" capsules).

Figure 4-1 shows the location of the various irradiation surveillance capsule assemblies within the Palisades pressure vessel.

Two surveillance capsules for monitoring the effects of operating temperature on the Palisades reactor pressure vessel material were also inserted prior to plant startup.

In Figure 4-1, note their location in relation to the reactor core.

Capsules T-330 and W-290 were removed af ter 4.975 effective full power years of plant operation.

Per reference (1), the Combustion Engineering description of the Palisades surveillance program, each of these capsules contained Charpy V-notch impact and tensile test specimens (Figure 4-2) from the intermediate shell course plate, from submerged arc weld metal representative of the core region of the reactor vessel, and from the weld heat affected zone (HAZ) material.

The chemistry of the surveillance materials, as reported by Combustion II)

Engineering

, are presen tec in Table 4-1.

The chemical analyses reported in Table 4-1 were obtained from unirradiated material used in the surveillarce program. The surveillance plate material was cut directly from the inter-mediate shell course plate, and thus received the same heat treatment.

The surveillance material received 1 3/4 hours interstage and 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br /> final heat, at 1150 + 25 F(1)

The base metal test materiai was fabricated from plate no. D-3803-1.

The weld metal test material was fabricated by welding together intermediate shell plate nos. D-3803-1 and D-3803-2.

For the weld metal ~ specimens, the Charpy V-no'tch specimen's were oriented with the major axis of the' specimen transverse to the welding direction, while the tensile specimens were oriented ~with the major axis of the specimen parallel to the welding direction.

The flux monitors were fabricated using six materials as neutron threshold-detectors -- uranium, sulfur, iron, nickel, copper and titanium. Two sets of flux monitors were~ installed in each tensile-monitor compartment. One set of '

flux. monitors, consisting of the.six different materials, are used to

-determine the neutron spectrum. Each detector was placed inside a grooved' 1/8-inch. sheath of 304 stainless steel (plain quartz in the case of sulfur)-

which-is used to identify the material and'to facilitate handling. Cadmium covers were used for those materials which have competing thermal activities (i.e'.,_ uranium, nickel and copper). The second set of monitors is composed of

' iron wires placed inside a grooved 1/16-inch sheath of 304 stainless steel,

~and-they. serve to evaluate the flux attenuation through the thickness of the

~

Charpy specimen.

TESTING OF SPECIMENS FROM CAPSULES T-330 AND W-290 i

OVERVIEW

1. r The postirradiation mechanical testing of the thermal and irradiated capsules' 4

Charpy V-notch and tensile specimens was performed at the Westinghouse Research and Development Laboratory, with consultation by Westinghouse Nuclear 1

=

Energy Systems personnel.

Testing was performed in accordance with 10CFR50, h

2 Appendices G and H, ASTM Specification E185-82 and Westinghouse Procedures RMFs 8402-0, 8102-0, and 8103-0.

Y Upon receipt of the capsules at the laboratory, they were opened in accordance lg with Westinghouse Procedure RMF 8404-0.

The specimens and spacer blocks were y'

carefully removed, inspected for identification number, and checked against s

the master list in C-E's summary report.[1] No discrepancies were found.

^*

S"

=

Examination of the four types of low-melting (536, 558, 580 and 590 F) alloys indicated no melting of any of the thermal monitors.

[

fa Samples of both the surveillance capsule plate and weld metal materials were chemically analyzed for the elemental content of Cr, Cu, Mn, Mo, and Ni (by an emission spectroscopy inductively coupled plasma method), and for P and Si eT (through wet analysis techniques).

i f

The Charpy impact tests were performed per ASTM Specification E23-82 and RMF

_r Procedure 8103 on a Tinius-Olsen Model 74, 359J machine.

The tup (striker) of

_l([

the Charpy machine is instrumented with an Effects Technology Model 500

}

instrumentation system. With this system, load-time and energy-time signals I

can be recorded in addition to the standard measurement of Charpy energy

[

(E ).

From the load-time curve, the load of general yielding (Pgy), the h

D time to general yielding (tGY), the maximum load (P ). and the time to f

M maximum load (t ) can be determined. Under some test conditions, a sharp

{

y drop in load inoicative of fast fracture was observed.

The load at which fast A_

r E

80928:1b-102984 5-1 T

' fracture was initiated is identified as the fast fracture load (P ), and the p

load at which fast fracture terminated is identified as the arrest load (P )*

A The energy at maximum Iced (E ) was determined by comparing the energy-time M

record and the load-time record.

The energy at maximum load is roughly equivalent to the energy required to initiate a crack in the specimen.

.Therefore, the propagation energy for the crack (E ) is the difference p

between the total energy to fracture (E ) and the energy at maximum load.

D The yield stress (cy) is calculated from the three point bend formula.

The flow stress is calculated from the average of the yield and maximum loads, also using the three point bend formula.

Percentage shear was ' determined from postfracture photographs using the ratio-of-areas m thods in compliance with ASTM Specification A370-77.

The lateral expansion was measured using a dial gage rig similar to that shown in the same specification.

Tension tests were performed on a 20,000 pound Instron, split-console test machine (Model 1115) per ASTM Specifications E8-83 and E21-79, and RMF Procedure 8102. All pull rods, grips, and pins were made of Inconel 718 hardened to Rc45. The upper pull rod was connected through a universal joint to improve axiality of loading. The tests were conducted at a constant crosshead speed of 0.05 inch per minute throughout the test.

Deflection measurements were made with a linear variable displacement transducer (LVDT) extensometer. The extensometer knife edges were spring-loaded to the specimen and operated through specimen failure. The extensometer guge length is 1.00 inch. The extensometer is rated as Class B-2 per ASTM E83-67.

Elevated test temperatures were obtained with a three-zone electric resistance split-tube furnace with a 9-inch hot zone. All tests were conducted in air.

Because of the difficulty in remotely attaching a thermocouple directly to the specimen, the following procedure was used to monitor specimen temperature.

8092B:1b-102984 5-2

r-R '

Chromel-alumel thermocouples were inserted in shallow holes in the center an'd each end of the gage section of a dummy specimen and in each grip.

In test.

. configuration, with a slight load on the specimen, a plot of specimen temperature versus upper and lower grip and controller temperatures was developed over the range room temperature to 550'F (288'C).

The upper grip was used to control the furnace temperature. During.the actual testing the grip temperatures were used to obtain desired specimen temperatures.

Experiments indicated that this method is accurate to plus or minus 2*F.

The yield load, ultimate load, fracture load, total elongation, and uniform elongation were determined directly from the load-extension curve.

The yield strength, ultimate strength, and fracture strength were calculated using the original cross-sectional area.- The final diameter and final gage length were determined from postfracture photographs.

The fracture area used to calculate t'e fracture stress (true stress at fracture) and percent reduction in area h

was computed using the final diameter measurement.

5-2.

THERMAL MONITOR MELTING Due to the lack of thermal monitor melting, questions arose as to whether the Palisades reactor was operating at a lower than design temperature, or whether the thermal monitor melting points were other than had been specified. To answer thie, a system, consisting of a troughed brass block resting on a hot plate, was rigged for melting the capsule thermal monitors. A thermocouple was placed in the trough with the monitor wire, and upon gradual heating the temperature of visually observable melting was noted. To prevent oxide formation from visually concealing the point of monitor melting, the monitors were coated with flux.

Prior to testing the Palisades thermal monitors, controls were run of calibrated Westinghouse thermal monitors.

Two Palisades thermal monitors (536 ard 590*F) (from capsule T-330) were then tested. The 590 F monitor melted at its rated temperature. The 536*F monitor melted only upon reaching 572*F, which indicates that the 536*F monitor has a much higher melting point and therefore is not truly a 536*F monitor. A 558'F monitor from capsult W-290 was then tested and resulted in a melting temperature of 590*F. Based on 80928:1b-102984 5-3

CHARPY V-NOTCH IMPACT TEST RESULTS Capsule T-330:

The results of the Charpy V-notch-impact tests performed on the various materials contained in Capsule T-330, the thermal capsule,' are presented in

~

Tables 5-2 through 5-9 and Figures 5-1 th' rough 5-4.

From the Charpy V-notch

. plots based on'best engineering judgement it appears that the weld and heat-affected zone metals have experienced a 60 to 70*F shif t in the ductile:

to brittle transition temperatures due to exposure to elevated temperature,-

but no decrease in upper shelf energy.

The fracture appearance of each Charpy specimen from the varicus materials is

~

shown in Figures 5-5 through 5-8, and show an increasing ductile or tougher

. appearance with increasing test temperature.

A typical instrumented Charpy curve, representing the curves of both Capsule T-330 and Capsule W-290, is presented in Figure 5-9.

l Capsule W-290:

The results of the Charpy V-notch impact tests performed on the various 19 2

materials contained in Capsule W-290, irradiated at 1.09 x 10 n/cm, are presented in Tables 5-10 through 5-17 and Figures 5-10 through 5-13.

A summary of the transition temperature increases and upper shelf energy decreases for the Capsule W-290 material is shown in Table 5-18.

Irradiation of the vessel ~ intermediate shell course plate D-3803-1 (transverse 19 orientation) to 1.09 x 10 n/cm2 (Figure 5-10) resulted in 30 and 50 ft-lb transition temperature increases of 155 and 160*F, respectively, and an upper shelf energy decrease of 18 ft-lb.

Irradiation of the vessel intermediate 19 2

shell plate material (longitudinal orientation) to 1.09 x 10 n/cm (Figure 5-11) resulted in 30 and 50 ft-lb transition temperature increases of 175 and 180*F, respectively, and an' upper shelf energy decrease of 43 ft-lb.

19 Weld metal irradiated to 1.09 x 10 n/cm2 (Figure 5-12) resulted in 30 and 50 ft-lb transition temperature increases of 290 and 300*F, respectively, and an upper shelf energy decrease of 54 ft-lb.

19 Weld HAZ metal irradiated to 1.09 x 10 n/cm2 (Figure 5-13) resulted in 30 and 50 ft-lb transition temperature increases of 235 and 245 F, respectively, and an upper shelf energy decrease of 44 ft-lb.

The fracture appearance of each irradiated Charpy specimen from the various materials is shown in Figures 5-14 through 5-17 and show an increasing ductile or tougher appearance with increasing test temperature.

Figure 5-18 shows a comparison of the 30 ft-lb transition temperature increases for the various Palisades surveillance materials with predicted increases using the methods of NRC Regulatory Guide 1.99, Revision 1.[3]

(

A-The regulatory curves used for comparison were developed from the average copper and phosphorus contents (averages of the analyses presented in Tables F-4-1 and 5-1) of plate 0-3803-1 and the weld metal.

This comparison shows that the plate transition temperature increases resulting from irradiation to 1.09 19 2

x 10 n/cm are less than predicted by the Guide for plate D-3803-1.

The I

19 7

weld metal transition temperature increase resulting from 1.09 x 10 i

n/cm is greater than predicted by the Guide. This can be explained by the high nickel content of the weld metal.

It is widely recognized today that j

nickel has a profound effect upon the irradiation damage of reactor vessel materials, whereas the current revision of Regulatory Guide 1 99 does not incorporate this iniportant variable.

7-y g ( ~ 4 m -SECTION 61 RA0!ATION ANALYSIS AND NEUTRON 00SIMETRY: ~6-1h INTR 000CTION. IKnowledge of the neutron environment within the pressure vessel / surveillance, capsule' geometry is required'as an integral part of LWR pressure vessel-- surveillance programs.for two reasons. First, in-the interpretation of radiation-indu::ed properties changes observed in materials - test. specimens the neutron environment.(fluence, flux).to which the. test specimens were exposed-must be known. Second in relating the changes observed in the test specimens to the present and future condition of-the reactor pressure ' tssel, a relationship must be established between the environment at various positions ~within the reactor vessel and that-experienced by the test specimens. The former requirement is normally met by employing a combinattu..of rigorous analytical techniques and measurements obtained with passive neutron flux monitors contained in the surveillance capsule. The latter information is derived solely from bench-marked analyses. { 1his section describes a discrete ordinates.S, transport analysis performed for the Palisades reactor to determine the fast neutron (E > 1.0 MeV)' flux and fluence as well.as the neutron energy spectra within the reactor vessel and surveillance capsule. The analytical data were then used to develop a lead factor for use in relating neutron exposure of the pressure vessel to that of the surveillance capsule. Based on spectrum-averaged reaction cross sections derived from this calculation, the analysis of the neutron dosimetry contained in Capsule W-290 is discussed and comparisons with analytical predictions are presented. 1 6.2. DISCRETE ORDINATES ANALYSIS A plan view of Palisades reactor geometry at core midplane is shown in Figure 6-1. Since the reactor exhibits 1/8 th core symmetry, only a zero to 45 degree sector is depicted.

program. A plan view of the surveillance capsules attached to the reactor vessel is shown in Figure 6-2A. As seen in Figure 6-28, the stainless steel capsule holder is basically a 1.503-inch by 2.178-inch rectangular tube with'a 0.12 inch wall. The monitors are' embedded in carbon steel. .From a neutronic standpoint, the surteillance capsule structures are significant. In fact, as is shown later, they have a marked effect on the distributions of neutron flux and energy spectra in the water annulus between the core barrel and the reactor vessel. Thus, in order to properly ascertain the neutron environment at the test specimen locations, the capsules themselves must be included in the analytical model. Use of at least a two-dimensional computation is therefore mandatory. In the analysis of the neutron environment within the Palisades reactor geometry, predictions of neutron flux magnitude and energy spectra were made with the 00T two-dimensional discrete ordinates code. The radial and azimuthal distributions were obtained from an R,0 computation wherein the geometry shown in Figure 6-1 was described in the analytical model. The R,0 analyses employed 26 neutron energy groups and a P expansion of 3 the scattering cross sections. lhe cross sections used in the analyses were obtained from the_SAll.0R cross section library which was developed specifically for light water reactor applications. The neutron energy group structure used in the analysis is listed in Table 6-1. A key input parameter in the analysis of the integrated fast neutron exposure of the reactor vessel is the core power distribution. For this analysis, Palisades Cycle 5 power distributions were employed. These input distributions include rod-by-rod spatial variations for all peripheral fuel assemblies. Having the results of the 4,0 calculation and an axial peaking factor, three-dimensional variations of neutron flux may be approximated by assuming that the following relation holds for the applicable regions of the reactor. 4 6-6 81488:lb/092684

The ffrst five reactions in Table 6-2 are used as fast neutron monitors to relate neutron fluence (E > 1.0 MeV) to measured material property changes.

g The use of passive monitors such as those listed in Table 6-2 does not yield a direct measure of the energy-dependent flux level at the point of interest. Rather, the activation or fission process is a measure of the integrated effect that the time-and energy-dependent neutron flux has on the tirget material over the course of the irradiation period. An accurate assessment of the average neutron flux level incident on the various monitors may be derived from the activation measurements only if the irradiation parameters are well known. In particular, the following variables are of interest, o The operating history of the reactor o The energy response of the monitor o The neutron energy spectrum at the monitor location l o. The physical characteristics of the monitor The analysis of the passive monitors and subsequent derivation of the average neutron flux requires completion of two operations. First, the disintegration rate of product isotope per unit mass of monitor must be determined.

Second, in order to define a suitable spectrum-ave. aged reaction cross section, the neutron energy spectrum at the monitor location must be calculated.

The specific activity of each of the monitors is determined using established ASTM procedures. ,8,9, M, H ) Following sample preparation, the activity of each monitor is determined by means of a lithium-drifted germanium, Ge(Li), gamma spectrometer. The overall standard deviation of the measured data is a l function of the precision of sample weighing, the uncertainty in counting, and the acceptable error in detector calibration. For the samples removed from Palisades, the overall 2a deviation in the measured data is determined to be plus or minus 10 percent. The neutron energy spectra are determined analytically using the method described in paragraph 6-1. Having the measured activity of the monitors and the neutron energy spectra at the locations of interest, the calculation of the neutron flux proceeds as follows. The reaction product activity in the monitor 1:, expressed as N { n P R=[f j.1 [ max(1-e-U ) e ~Md (6-2) Y.J a(E)+(E)dE I j g E 81488:lb/092084 6-9 2- ,. ; ' ;-. _ sg : _ ;.. .4 ': '_'";+',e ' *i ' f; I,,hi ^. e ~ *;* h l.f ^

in order to_ derive neutron flux and fluence levels from the measured disintegration rates, suitable spectum-averaged reaction cross sections are required. The neutron energy spectrum calculated to exist at the center of Palisades capsule is listed in Table 6-3. The associated spectrum-averaged cross sections for each of the fast neutron reactions are given in Table 6-4, 6-5. 00SIMETRY RESULTS lhe irradiation history of the Palisades reactor up to the time of removal of Capsule W-290 is listed in lable 6-5. Comparisons of measured and calculated saturated activity of the flux monitors contained in Capsule W-290 based on the irradiation history shown in Table 6-5 are given in Table 6-6. The fast neutron (E > 1.0 MeV) flux and fluence levels derived for-Capsule W-290 are presented in Table 6-7. An examination of Table 6-7 shows that the fast neutron flux (E > 1.0 MeV) 10 derived from the five threshold reactions ranges from 6.48 x 10 to 10 2 7.84 x 10 n/cm -sec, a total span of 30 percent. It may also be noted 10 2 that the calculated flux value of 8.32 x 10 n/cm -sec exceeds all of the measured values, with calculation to experimental ratios ranging from 1.06 to 1.28. Comparisons of measured and calculated current fast neutron exposures for Capsule W-290 as well as for the inner radius of the pressure vessel are presented in Table 6-8. Measured values are given based on the Fe (n,p) Mn reaction alone as well as for the average of all five threshold reactions. Based on the average data given in Table 6-8, the best estimate exposure of Capsule W-290 is I9 4T = 1.09 x 10 n/cm2 (E > 1 MeV) In addition, a fast neutron flux check was made of a fractured Charpy V-notch specimen from the thermal capsule, Capsule T-330. This analysis showed that Capsule T-330 was exposed to only a very minimal level of fast neutron flux, six orders of magnitude less than the exposure of Capsule W-290. 81488:lb/092584 6-21
