0 INTRODUCTION The primary purpose of the analyses reported herein is to resolve questions raised concerning a mix-up of the base metal materials used in the Nine Mile Point Unit 1 (NMP-1) surveillance program. As described in Section 2.0, it,has been conclusively demonstrated that a material mix-up did occur during fabrication of the surveillance capsule specimens. Conclusions concerning the actual materials used in the surveillance program are presented in Section 2.5. Since some of these materials were included in the re-encapsulation capsules A'nd C', a re-evaluation of the specimen inventories for the re-encapsulation capsules and the remaining B capsule was conducted. These esults are pxesented in Section 2.6. Since the surveillance program is based on materials which are not limiting from an embrittlement perspective, it was necessary to develop an adjustment methodology so that the surveillance data can be used in P-T analysis. This methodology is described in Section 2.7.

In addition to the material mix-up analysis, additional Charpy tests were conducted to determine the RT>>T of plate G-8-3.

These results are provided in Section 3.0. In Section 4.0, the capsule A'nd C'rchive dosimetry and thermal monitor storage plan is presented. Finally, summary and conclusions are presented in Section 5.0.

In response to the material mix-up, this report is intended to serve as a new baseline pressure vessel materials report.

any of the earlier documents are in error and should only be used in the future with caution. This report contains all of the data and information needed to evaluate future surveillance capsules and prepare Pressure-Temperature (P-T) operating curves.

1.1 Historical Pers ective Three surveillance capsules were installed in the NMP-1 reactor in 1969 prior to initial operation. Two of the capsules have been removed to date. References [ST84] and [MA85a] contain the results of tests performed on the contents of these capsules.

The number and type of mechanical behavior specimens, as well as the capsule identification and location within the reactor vessel, are summarized in Table 1-1. Figure 1-1 shows the location of the surveillance capsules. Prior to the material mix-up analysis, the base metal Charpy 30 ft-lb index shift (BT3Q) of 114'F for plate G-8-3 was thought to be larger than the shift predicted by Regulatory Guide 1.99 (Revision 2) [RG1.99(2)]

by a statistically significant amount. Since plant life extension is being considered, Niagara Mohawk decided to reinsert two capsules (A'nd C'). The prime is used to designate the new capsule in the same azimuthal location as the original capsules.

The radial location of the new capsules is slightly closer to the core than the original capsules to increase the neutron flux.

The mechanical behavior specimens which were included in the new capsules are summarized in Table 1-2.

1.1.1

~ ~ REVISED SURVEILLANCE PROGRAM DESCRIPTION A detailed description of the original surveillance program was given in reference [ST84]. Three surveillance capsules, each containing Charpy and tensile specimens, as well as dosimetry wires [iron (Fe), copper (Cu), and nickel (Ni)], were installed in the NMP-1 pressure vessel prior to initial startup. As of the date of this report, two capsules have been removed as described earlier [ST84, MA85a] .

The full contents from the C capsule, 24 Charpy specimens and 6 tensile specimens, were tested at Battelle in 1983 to determine tensile properties and reactor vessel base metal, weld metal, and heat affected zone (HAZ) Charpy impact nil-ductility transition temperatures (NDTT) [ST84] . Six Charpy base metal

~

specimens from the A capsule were also tested at Battelle to

~

confirm the 30-ft-lb shift of the base metal observed in the C capsule specimens [MA85a]. In addition, one base metal tensile specimen from the A capsule was tested in order to further benchmark the correlation between change in yield strength and shifts in the 30 ft-lb temperature.

MPR Associates, Inc. reviewed the NMP-1 data, and recommended to Niagara Mohawk that two capsules be reinserted during the 1986 refueling outage [NE85]. Battelle provided neutron transport data to MPR for calculation of the desired radial position of the reinserted capsules [MA85b]. A description of the revised surveillance program is provided in

~ <<4>>, V ~ <<p'is QJl ~+ I l4, .g I, 0

reference [MA85c] and is summarized below.

Charpy and tensile base metal, weld metal and HAZ specimens from the A capsule were returned to the reactor vessel in a new capsule which was installed at the A location (30 degrees azimuth), during the 1986 refueling outage. The six Charpy base metal specimens from the A capsule which were tested, were reconstituted prior to reinsertion. One tensile base metal specimen from the original A capsule was tested and machined into two miniature specimens and inserted in the new capsule. In addition, five temperature monitors were installed in the reinsertion capsule to determine the maximum specimen temperatures experienced during reactor operation. The radial position of the reinsertion capsule relative to the reactor vessel wall was modified to increase the neutron flux at the capsule location by a factor of 1.97 over the maximum flux at the reactor vessel shell at the 1/4 T location. This lead factor will make up for the time the specimens were out of the reactor and allow the specimens to reach the anticipated end of life fluence at the time the 1/4 T position reaches 24 EFPY.

It is recognized that there may be a neutron flux effect which could result in different mechanical behavior for the reinserted samples as compared with regions of the vessel irradiated at a lower flux. However, the practical constraint of achieving timely data requires a higher flux at the reinsertion capsules than at the vessel. It is anticipated that future research will either confirm or negate the damage rate

~ %v 5 t'p

hypothesis. If necessary, a mechanistic damage model should provide adequate correlation between the surveillance data and the vessel.

Twelve reconstituted full-sized Charpy base metal and weld metal specimens and miniature tensile specimens machined from the broken tensile base metal and weld metal specimens from the C capsule were reinserted in the NMP-1 reactor vessel in a second new capsule at the C location (300 degrees azimuth). In addition, twelve unirradiated Charpy base metal specimens and three unirradiated tensile base metal specimens were installed in

'the reinserti'on capsule. The unirradiated specimens were machined from the NMP-1 reactor vessel archive plate material (G-8-3) which was used in the original weld and HAZ surveillance specimen fabrication. No HAZ specimens were included in this capsule since the observed shift for the HAZ specimens tested to date is negligible, and the HAZ shift is expected to be bracketed by the base metal and weld metal shifts. The C'einsertion capsule also contains five temperature monitors. The same lead factor was used for the C'apsule as was used for the A'apsule.

The revised withdrawal schedule and the exposure for each mechanical behavior specimen set is summarized in Table 1-3. At one-half of original design vessel life (16 efpy), the original B capsule will be withdrawn and the specimens tested. These data will provide information on the current tensile properties and Charpy shift of the reactor vessel base metal, weld metal, and

At three-quarters of original vessel design life (24 efpy),

the reinsertion A'apsule will be withdrawn. Due to the 1.97 lead factor on this capsule, the exposure of the A'apsule specimens will be approximately equal to the vessel 1/4 T at end of life. Results of mechanical behavior tests for the A'apsule contents will provide information on end-of-life tensile properties and Charpy shift of reactor vessel base metal, weld metal, and HAZ.

At end of vessel life (32 efpy), the reinsertion C'apsule will be withdrawn. Due to the 1.97 lead factor on this capsule, the exposure of the previously irradiated and unirradiated specimens will be equal to 155% and 133% of originalC'apsule esign exposure. Results of mechanical behavior tests on the unirradiated C'apsule contents will provide information on the tensile properties and the Charpy shift of the reactor vessel base metal for a plant life extension of 133 percent. Results of tests on the previously irradiated C'apsule contents will provide information on tensile properties and Charpy shift of reactor vessel base metal and weld metal for a life extension of 155 percent.

A detailed description of the reinserted capsules is provided in Appendices A through E.

1.1.2 Materials Mix-U Concern The Niagara Mohawk Power Corporation surveillance program 10

I or NMP-1 is described in reports issued by the General Electric Company [HI69, APED]. Further details and mechanical properties are contained in references [H065a, CE64, CE65, LE64, ST64, H065b, LU85, BU85, ST84, MA87, MA85a, MA85b,]. Reference [H065a]

specified that "all base metal shall be taken from two plates (G-8-3 and G-8-4); and all weld and heat affected metal shall be taken from the weld metal between the plates (Code G-8-3 and Code G-8-4).'" The surveillance test results reported in references

[ST84] and [MA85a] were reported based on this understanding. As shown in Section 2.0, the base metal Charpy specimens were

'ctually 'fabricated from plate G-8-1. This, of course, has a significant effect on the measured Charpy shift and necessitates recalculation of many of the results reported in [ST84] and MA85a]. In addition, it was necessary to analyze the surveillance capsule (capsules A', B, and C') inventories and clearly identify the materials present in these capsules.

Reference [H065a] also lists the orientation of the Charpy and tensile specimens within the plate. It is assumed that the orientation of the specimens cut from plate G-8-1 is identical to that specified in reference [H065a]. The specification states that base metal specimens were taken from flat slabs cut parallel to both the plate surfaces at a depth of one-quarter and three-quarter plate thickness. The Charpy and tensile base metal specimens were machined with their long axes parallel to the plate rolling direction and the Charpy specimen notches were cut perpendicular to the plate surface. Both Charpy and tensile base

~ I 'A Cy h~~

etal specimens were designated longitudinal specimens.

The weld metal for the NMP-1 pressure vessel was welded in accordance with the Combustion Engineering Welding Specification SAA-33-A(3) and NA-33-A(7) using the submerged arc process

[LE64]. The Charpy weld metal specimens were machined in a direction transverse to the weld direction; thus, only the central notched section of the specimen would necessarily be composed of weld-deposited metal. Charpy specimens were taken throughout the weld section to a depth of 1-1/16 inch from the weld root. The Charpy weld metal specimens'ong axes were therefore'arallel to the plate surface, and the notches were cut perpendicular to the plate surface. The tensile weld metal specimens were composed entirely of weld metal and were obtained y machining the specimens parallel to the weld length and parallel to the plate surface.

The Charpy HAZ metal specimens were machined in a direction transverse to the weld length and parallel to the plate surface.

The axes of the notches were then cut perpendicular to the plate surface, with the notch located at the intersection of the base metal and weld deposit. The tensile HAZ metal specimens were machined transverse to the weld length and parallel to the plate surface. The joint between the base metal and weld deposit was located at the center of the tensile specimen gage length.

Analysis of the chemistry data reported in [NA87] indicates that the base metal Charpy specimens were fabricated from plate G-8-1 and the weld and HAZ base metal came from welded G-8-3 12

lates. In addition, Y. Soong of Niagara Mohawk analyzed the reference [CE65] drawing and produced the drawings shown in Figures 1-2 and 2-7. A total of five nozzle cuts were made in the beltline region: two from plate G-8-1, two from plate G-8-3 (one of these was at the G-8-3/G-8-4 interface), and one from plate G-8-4. Therefore, the surveillance material had to come from these dropouts. In order to confirm the hypothesis that the base metal Charpys are from G-8-1, chemistry and mechanical behavior tests and analyses were performed. The detailed scope of work is described in Section 1.2.

.2 Detailed Work Sco e A detailed description of the work undertaken in the present study is given below.

1.2.1 Re-evaluate Data and Write New Surveillance Pro ram As a result of the findings described above, much of the Reference [ST84, NA85a, and MA87] data are in error and the current P-T curves are overly conservative. Also, many of the surveillance program reference documents are in error or are misleading. To attempt to rectify this situation, a new surveillance program description has been written and included herein. This report supercedes all previous documents and ontains all of the information necessary to conduct the program in the future. Zn addition, several analyses were conducted to correct and update existing data. These include:

(1) Fit all unirradiated beltline Charpy data using the Weibull model.

(2) Clearly indicate which materials are G-8-1 and G-8-3. For specimens which are currently being irradiated, those for which there is some uncertainty regarding the material composition have been identified.

(3) Correlate tensile, Charpy, hardness, and chemistry data to demonstrate that base metal specimens were cut from Plate G-8-1 and weld and HAZ specimens were cut from G-8-3.

(4) Develop a correlation factor which relates data on Plates G-8-3 and G-8-1 with Plate G-307-4.

15

(5) Note several cautions for the future:

(a) Not all of the in-service capsule material compositions are known.

(b) The GE machined Charpy notches for the re-encapulation program may be out of specification. Several of the unirradiated Charpy specimens which were machined at GE and tested at Battelle were remachined prior to testing. The tensile specimens may exhibit bending during testing. There is experimental evidence that the GE machined specimens were not within ASTM specifications. During the test, evidence of bending which results in significant uncertainty in the yield strength determination was observed.

(6) Test reconstituted Charpy specimens from 300'apsule HAZ specimens to establish the Plate G-8-3 bTpp.

Reconstitution and testing of 6 HAZ base metal halves (Plate G-8-3) was performed. In addition, chemical analyses were performed on the base metal taken from a HAZ specimen to verify that the material is G-8-3.

These Charpy tests provide surveillance data on Plate G-8-3.

Perform tensile and hardness measurements on plates G-8-3 and G-8-1. Unirradiated tensile tests were rerun with more accurately machined specimens cut from plate G-8-3. In addition, miniature tensile specimens machined from the base portion of weld Charpy specimens were tested. These data were needed to develop the tensile correlation. Hardness measurements were made on both plate materials for the same purpose as the tensile data.

1.2.2 Determine Initial RT of Beltline

~ Materials The initial RT>>~ for the beltline plates and welds were not determined in accordance with current ASME requirements. The current rationale for using +10 F is weak. Therefore, it was necessary to obtain data and perform analyses to firmly establish 16

he initial RTNqq.

~

~ In the case of plate G-8-3, unirradiated Charpy and drop weight tests were performed to establish the RT~~

in strict conformance with the ASME code. A total of 18 unirradiated Charpy specimens oriented normal to the rolling direction were tested in the current study. For the remainder of the beltline materials, an analytical technique was used to conservatively calculate the RT>>~. The results are provided in Section 3.0 and Appendix L.

1.2.3 Enca sulate Archive Dosimetr and Tem erature Monitor Materials As discussed in Reference [MA87], the archive dosimetry and temperature monitor materials should be carefully stored until apsules A'nd C're pulled, tested, and analyzed. Ne recommend storage in evacuated quartz tubes. This work was done to ensure adequate protection from humidity and the encapsulated materials should be stored in a temperature controlled environment.

1.3 A licable Documents As mentioned earlier, this report serves as the new baseline beltline pressure vessel materials document and supersedes all previous reports'll of the relevant data needed to conduct the surveillance program have been extracted from earlier reports and included in this report. In cases where the material composition I

is different than previously thought, the correct composition is indicated and the change noted. The data tables in the appendices 17

have been correctly changed and footnoted to indicate these changes. Examination of any of"the

earlier references must be done with caution. In order to provide traceability, a comprehensive listing of'the references which pertain to the beltline surveillance program are given in Table 1-4. Comments pertaining to the material mix-up have been provided as appropriate.

1l Q4S4 IW p 0 MATERIAL MIX-UP ANALYSIS This section contains the data supporting the conclusion that a material mix-up in the NMP-1 surveillance program did occur. A conclusive demonstration was made using the reference [MA87]

chemistry data. These data are reviewed in Section F 1. In addition, the mechanical behavior trends were examined to confirm the chemistry data, and these findings are discussed in Sections 2.2 2.4. Conclusions concerning the mix-up, the impact on the material inventories, and a discussion of the limiting plate adjustment methodology are given in Sections 2.5-2.7.

2.1 Chemistr Anal sis As described in reference [MA87], the method of Inductively Coupled Argon Plasma (ICAP) Spectrometry was the primary chemical analysis method used. In addition to the ICAP measurements, the atomic absorption (AA) method was performed to determine the Cu and Ni content of the samples as an independent check. The test matrix is summarized in Table 2-1.

As stated in [MA87], the primary goals of the chemical analysis task were: to determine whether the differences in the reference [ST84] and [MA85a] measurements are due to the XRF technique; to determine whether the unirradiated plate chemistry matches the Lukens data; and to determine whether there are any observable chemistry differences between the Charpy base metal 22

pecimens fabricated from the nozzle dropout (30-degree and 300-degree base metal specimens) and the specimens fabricated from other regions in the G-8-3 and G-8-4 plates (HAZ specimens and unirradiated plate).

At least three ICAP measurements per sample were made so that the uncertainty could be quantified. The WNAL measu'rements examined all of the elements on the Lukens record. In addition, one AA backup measurement per specimen type and one backup colormetric measurement for P content were made.

Four specimen categories were analyzed and the specimen identifications are summarized in Table 2-2. Chemistry data from the Lukens test certificates [LU64] and the Lukens measured Cu content from reference [LU85) is shown in Table 2-3. The results of the chemical analyses are provided in Appendix F and in "Figures-'2-1 'through 2-6.

t As discussed in Section. 1.1, nozzle drop out material was available from plates G-8-1, G-8-3, and G-8-4. Plates -G-8-3 and G-8-4 are from the same heat, have identical composition, and therefore behave the same from a radiation damage viewpoint.

,Examination of Figures 2-1 through 2-6 indicates that the chemistry of the base metal Charpy specimens closely matches that of the plate G-8-1 Luken's ladel analysis, whereas the chemistry of the base material from the Charpy HAZ specimens 'closely matches the.unirradiated archive G-8-3 plates and the Lukens G 3 ladel analysis. However, this observation is not consistent with reference "[H065a] which specified that all of the base metal material should be prepared from plates G-8-3 and G-8-4. A plausible explanation is that between the time the [H065a]

pecification was written and the time the specimens were fabricated, a decision was made to fabricate the base metal Charpy specimens using the G-8-1 material because the Cu content is higher in the G-8-1 material and closer to the highest Cu plate in the beltline region (G-307-4). Also, as shown in Figure 2-7, one of the G-8-3 nozzle dropouts fell on the axial weld line. lt is possible that concern over including weld and HAZ material in the base metal Charpy specimens may have influenced the decision to machine the base metal specimens from plate G-8-1.

2 Tensile Data Anal sis The irradiated and unirradiated baseline tensile data are provided in Appendix G. Also miniature tensile specimens were machined from the base metal portion of the weld specimens.

These data are provided in Appendix G as well.

Prior to the preparation of the [MA87] report, GE machined and sent tensile specimens to Battelle to measure the archive plate G-8-3 unirradiated properties (T03, T22, T23) and for use in the C'apsule (T01, T02, T21). There is experimental evidence that the GE machined specimens were not within ASTM specifications. During the test, evidence of bending was observed which would result in significant uncertainty in the yield strength determination. As a result, these tests were iscarded (T01, T22, T23) were rerun using specimens machined at Battelle (TN1, TN2, TN3). These data are presented in Appendix G 3.

~ Care should be exercised when specimens T01, T02, and T21 from capsule C're tested since these specimens were machined in the same batch at G.E. as the specimens which exhibited bending during testing.

An analysis was performed to determine the material from 1

which the surveillance program tensile specimens were machined.

Unfortunately, there is no irradiated base metal tensile specimen material available at present for chemical analysis. Therefore, the composition of the original base metal tensile specimens is unknown and must be determined in the future when the surveillance capsules are withdrawn. The only tensile specimens 35

vailable for testing at present are the HAZ tensile specimens JUD and JTU. The base metal portion of JUD was analyzed and the results are given in Appendix F. As suspected, the chemistry of this material matches that of plate G-8-3. Therefore, it is likely that all of the HAZ tensile specimens were prepared using plate G-8-3 material. The weld specimens are composed entirely of weld metal.

A summary of the room temperature tensile behavior data is given in Table 2-4. Several valuable insights can be gained by examining these data:

~ 'he "TN-1 data (plate G-8-3 tested in 1990) is consistent with the 1964 CE data for the same plate.

~ The plate G-8-1 and G-8-3 unirradiated tensile properties are essentially identical. As discussed in reference [OD85], the uncertainty in the average yield strength change (boy) for the LWR data base is about 3 3.5 ksi, with individual uncertainties as high as 10 ksi. Therefore, for the same heat of material, we would expect that values with + 3-5 ksi would indicate similar material behavior.

~ Based on chemical analysis, it is believed that all HAZ and weld CVNs were fabricated using plate G-8-3.

Therefore, specimen EJD is most likely irradiated G-8-3 material.

'I

~ Assuming EJD represents irradiated G-8-3 material, and JJA was prepared from G-8-1 material, we would expect the change in yield strength to be larger for the JJA specimen. These assumptions are consistent with the

)

data given in Table 2-4. A comparison of the bT30 using the reference [OD85] yield strength correlation and the RG1.99(2) model is shown in Table 2-5.

~ Based on these observations, a plausible interpretation of the tensile data is that the HAZ and weld (entirely

- weld metal) tensile specimens were fabricated using plate G-8-3 and the base specimens were fabricated using plate G-8-1 material. This interpretation is consistent with the way in which the Charpy specimens were fabricated. This hypothesis must be verified in the future by chemical analysis when the capsules are withdrawn.

.3 Cha Data Anal sis Appendix H contains all of the Charpy data generated to date. The unirradiated 1964 data for the beltline plates (L-T orientation) was fit using the SAM McFRAC code [MC89]. The plots are given in Appendix H.1 and the indices are summarized in Table 2-6. Additional tests were conducted on plate G-8-3 using specimens with both the L-T and T-L orientation. The L-T to T-L orientation change results in an average upward shift of 24'F of the Charpy curve at the 30 ft-lb level. These data are summarized in Table 2-7.

One concern raised by the data presented in Table 2-7 is the relatively low USE exhibited by plate G-8-3 tested in the T-L rientation. ~ Analyses should be conducted in the future to determine the radiation damage effects on the

~

USE decrement.

The irradiated base metal data from the 300 and 30 degree capsules and the weld and HAZ data from the 300 degree capsule were fit using the McFRAC code, and the results are presented in Appendix H.2. As described earlier, it is believed that the base metal specimens were machined from plate G-8-1. In order to further confirm this hypothesis, six specimens were reconstituted using base metal from the 300 degree capsule HAZ Charpy specimens. These data are also presented in Appendix H.2. It is believed that these specimens were prepared using plate G-8-3 material.

The irradiated material Charpy indices and 30 ft-lb shifts 40

re summarized in Table 2-8. Plots showing the effect of irradiation on the Charpy shift are shown in Figures 2-8 through 2-10. Flux and fluence data are provided in Appendix K. These data confirm the hypothesis concerning the material mix-up. As shown in Table 2-8, the measured shift for the G-8-1 material is higher at the higher fluence. Also, the G-8-3 shift is consistent with the lower Cu content. The measured BT~~s for the G-8-3 and G-8-1 materials are within the RG1.99(2) two sigma confidence band.

Overall, the Charpy data confirm the chemistry data trends

"'which show that the surveillance capsule base metal specimens came from plate G-8-1 and the HAZ and weld specimens were fabricated using G-8-3 base metal.

2. 4 HARDNESS DATA ANALYSIS N

Rockwell B and C hardness tests were performed on the unirradiated plate G-8-3 material and Charpy specimens from the 300 degree capsule. These data are provided in Appendix I. The Rockwell C tests were performed in, addition to the Rockwell B tests because the data fell high on r the Rockwell B scale. Future tests on more highly irradiated material may require the use of the Rockwell C scale. The broken Charpy specimens were indented after fracture testing. Specimens which exhibited little plastic deformation during Charpy testing were chosen so that the specimen was properly supported in the hardness test machine.

The specimens were tested on the surface containing the notch and on the surfaces normal to the notch. A slight orientation effect was observed. Overall, the orientation effect s not significant. The G-8-3 unirradiated material exhibited an average Rockwell C hardness of 10 ' and Rockwell B hardness of 89.9. The G-8-3 specimens irradiated to 4.78 x 10'/cm had an average Rockwell C hardness of 13.5 compared to an average of

,. 15.0 for the G-8-1 material, and an average Rockwell B hardness, of 91.8 for the G-8-3 material compared to 92.5 for the G-8-1 material. Therefore, the hardness data confirms the material mix-up hypothesis.

2.5 CONCLUSION

S CONCERNING MATERIAL MIX-UP Based on a careful examination of all of the NMP-1 surveillance data, the following conclusions have been made:

~ A material mix-up did occur in the NMP-1 surveillance program. This conclusion is based on definitive 48

chemical analysis data and further substantiated by examining the mechanical behavior trends.

The base metal Charpy specimens were prepared from plate G-8-1 material and the HAZ and weld specimens were prepared using G-8-3 material.

The HAZ tensile specimens were prepared using G-8-3 plate material. It is likely that the weld (entirely weld) tensile specimens were produced using the G-8-3 material. Based on the mechanical behavior trend, it is likely that the base metal tensile specimens were prepared from G-8-1 material. Additional analyses will be needed in the future to confirm the tensile materials.

~ When the capsules are pulled in the future, chemical analyses should be done on the following materials to confirm the base metal composition:

base metal from Charpy weld for the 30'nd 300'apsules, base, base from weld, and base from HAZ for Charpys in the 120'apsule, all tensile base metal specimens.

2.6 SURVEILLANCE CAPSULES A'nd C'ATERIALS Based on the conclusions drawn in Section 2.5, the current surveillance capsule inventories were reassessed and the material compositions indicated. These data are given in Tables 2-9 through 2-11 ~ As stated earlier, some specimen compositions must be confirmed in the future.

7 LZMZTZNG PLATE ADJUSTMENT METHODOLOGY As described earlier, the NMP-1 base metal surveillance program consists of irradiation and testing of Charpy specimens fabricated from both G-8.-1 and G-8-3 plate materials. The limiting plate, from a radiation damage perspective, is that plate with the highest copper and nickel content. As shown in Table 2-3, the plate G-307-4 has the chemistry which results in the largest RG 1 99(2) chemistry factor. As with many plants in

~

operation today, the surveillance material is not the limiting material. Therefore, in order to be able to use the surveillance data in P-T curve calculations, we are recommending the use of a "correction factor" which adjusts for the chemistry differences.

Zn essence, two factors are developed, (one for G-8-1 material and one for G-8-3 material) and used to map the surveillance data into plate G-307-4 equivalent data. The RG 1.99(2) chemistry factor data base was used to provide the correction terms. The results are given in Table 2-12. The adjustment factor derived is as follows:

3.0 BELTLINE MATERIAL INITIAL RT T DETERMINATION An analysis was performed to establish best estimate values for the RT>>T and 6, terms used in Regulatory Guide 1.99 (Rev. 2) calculations for the Nine Mile Point Unit 1 (NMP1) beltline plate and weld materials. With the exception of plate G-8-3, sufficient data are not available to determine the RT>>T in strict conformance with the current ASME code rules. In the case of the weld metals, only three unirradiated Charpy tests were conducted at 10'F Charpy transition behavior data are available for the

~

plate materials, however, there are no drop weight data (for all of the beltline materials except for plate G-8-3/G-8-4). The methodology used is described in detail in Appendix L. The results of these calculations are presented in Table 3-1.

As described in reference [MA87], the plate G-8-3 RT>>, could not be determined in accordance with the current ASME code requirements because the Charpy specimens tested at that time had an L-T orientation. Therefore, Charpy (Appendix H) and drop weight (Appendix J) tests were performed to firmly establish the initial RT>>T for plate G-8-3. Specimens machined from plate G 3 with the T-L orientation were tested as part of the current work. These data are presented in Appendices H.1.2 and H.1.3 and the results are summarized in Table 2-7. The L-T to T-L orientation change results'n an upward shift of the Charpy curve of 21 F. This is consistent with data in the literature [EP82].

The Charpy and drop weight data are summarized in Appendices H and J, respectively. The NDT determined by drop weight tests for 59

plate G-8-3 is -25 F. Three Charpy specimens with the T-L

~

orientation exhibited 50 ft.-lbs. of absorbed energy at 57 F.

~ ~

Therefore, the RT>>~ for plate G-8-3 is -3 F.

.0 ARCHIVE'OSIMETRY AND THERMAL MONITOR ENCAPSULATION In surveillance capsule irradiations, it is prudent to store dosimetry and temperature monitor materials in case it is necessary to resolve conflicts in the data obtained. With these materials, calibration experiments can be repeated; and, if necessary, neutron benchmark irradiations can be conducted.

Should definitive follow-on experiments of this type be needed, the availability of these archive materials can be a crucial factor in the success of the dosimetry analysis. To this end, archive materials, identical to those used in Capsules A'nd C',

have been provided to Niagara Mohawk. Tables 4-1 through 4-4 summarize the supplied archive materials for RM neutron d osimeters, SSTR neutron dosimeters, MW-TMs and SSTR-TMs, espectively. These materials were sealed inside an evacuated quartz tube and sent to Niagara Mohawk [MA89].

SUMMARY
AND CONCLUSIONS Based on careful examination of all data available, it has been concluded that a materials mix-up has occurred in the NMP-1 surveillance program. For the capsules which have been pulled to date, it has been conclusively demonstrated that the base metal Charpy specimens were fabricated from plate G-8-1, and not plate G-8-3 as originally specified. The base metal portion of Charpy weld and HAZ specimens is composed of plate G-8-3 material.
Future chemical analysis of capsule B materials and all base metal tensile specimens are needed to determine the composition
" of thesematerials. It is likely that the base metal tensile specimens were fabricated from plate G-8-1, and the same approach to specimen fabrication for capsule B was used as that used for apsules A and C.
As a result of these findings, this report was prepared and is intended to serve as the new baseline surveillance document for NMP-1. All of the data needed to conduct. the surveillance program is contained herein. Should future analysis require examination of earlier reports, these studies should be conducted with caution since the earlier reports are known to contain errors related to the material mixup.
In response to these findings, it is recommended that new P-T curves be prepared. The current P-T curves are overly conservative since the measured shift was determined using G-8-1 irradiated material and G-8-3 unirradiated material. The actual measured shifts, which have been corrected to account for the 66
Sgp
~"
C Ill.- s+ hl
aterial mix-up, are consistent with the [RG 1. 99 (2) ] model.
Therefore, it is recommended that Niagara Mohawk prepare new P-T curves to replace the current overly conservative curves.
5.1 Benefits to Nia ara Mohawk A substantial amount of work has been performed under the NMP-1 surveillance program since removal of the A and C capsules.
Capsule A was removed in 1979 after a vessel exposure of 5.8 effective full power years (efpy) and capsule C was removed in 1982 after a vessel exposure of 8 efpy. The culmination of this
" work is reported"herein and has resulted in the firm re-establishment of the NMP-1 surveillance program. A brief summary of the past problems, resolution of the problems, and the enefits of this work to Niagara Mohawk are presented below.
5.1.1 PLEX Surveillance The capsule C (at 300 azimuth) analysis showed a base metal BT3Q of 114 F at a fast fluence of 4.78 x 10"n/cm . In order to confirm this finding, the 30 degree capsule was analyzed and a base betal bT>> of 90 F =was measured at a fast fluence of 3.6 x 10'/cm . These data exceeded the RG 1.99(2) prediction by over 3 standard deviations.
In response to the concern raised by these findings, a surveillance capsule re-insertion program was undertaken. Two new capsules containing both irradiated and unirradiated (from archive) specimens were re-inserted. These are the first
J
,t l
apsules ever designed specifically to generate plant life extension data. These capsules are advanced BWR capsules and contain advanced dosimetry, temperature monitors, and innovative mechanical test specimens. The benefit to Niagara Mohawk will be end-of-license and life extension data'hese data can be used in plant specific damage models to yield accurate estimates of the K,~ curve shift for P-T calculations.
5.1.2 Material Mix-U Resolution Measurement and careful study of the material chemistry data "and as-'builtdrawings led to the discovery that a material mix-up had occurred in the NMP-1 surveillance program. The mechanical behavior trends were examined and found to confirm the chemistry ata. As a result, the plate G-8-3 (Cu = .18, Ni = .56) measured shift (hT>>), originally thought to be 114 F, was correctly established to be to 11 F at a fluence of 4.78 x 10 n/cm . Since the surveillance program is irradiating two plate materials (G 3 and G-8-1), the Charpy bT,~ can be determined for plate G-8-1 (Cu = .23, Ni = .51) as well. For plate G-8-1, bT~, = 79 F at a fluence of 4.78 x 10'/cm and ET3Q 55 F at a fluence of 3.6 x 10"n/cm . Therefore, the resolution of the material mix-up has resulted in three measured Charpy bT~,s instead of two, and the measured shifts are much lower than believed earlier.
68
.1.3
~ ~ Limitin Beltline Material As with many plants in operation today, the NMP-1 surveillance material is not the limiting beltline material ~
Based on the chemistry data and analysis of initial RT>>~ for the beltline materials, plate G-307-4 is the limiting material.
Therefore, in order to enable use of the surveillance data in P-T curve calculations, a correction factor which adjusts for the chemistry differences between G-307-4 and the surveillance materials (G-8-3 and G-8-1) has been developed. This approach allows Niagara Mohawk to use plant-specific data to determine the "ART>>~ 't'rend curve in accordance with the guidance provided in RG
1. 99 (2) .
~ 1' RT of Beltline Materials The RT>>~ of the beltline materials, with the exception of plate G-8-3, cannot be measured in conformance with the ASME code requirements. A value of +10 F has been assumed. Should the NRC decide to question the assumption, Niagara Mohawk would be vulnerable. However, a rigorous statistical method which is consistent with the intent of the ASME code was used to determine the RT>>~ of all of the beltline materials. Xn the case of the welds, it has been demonstrated that the +10 F assumption is overly conservative, and for the plates, the +10 F assumption is non-conservative. Although the RT>>~ for the limiting plate (G-307-4) was found to be 40 F, the analaysis enables identification of the actual limiting material Following the RG 1.99(2)
~
69
V 'j.'
~ Jl,
approach, the weld materials would have been limiting since the regulatory guide requires the use of .35% Cu and 1.0% Ni in cases where measured chemistry data are not available. This chemistry assumption leads to a chemistry factor of 272 for the weld material as apposed to 174 for the limiting plate. Therefore, weld material would have been limiting and the ARTgT for the weld would have been larger than that for the plate if the RTND~
analysis had not been done.
5.1.5 Si nificant Economic Benefits in H dro-test
'"The hydro-test temperature has been reduced significantly
(-20F) as evidenced by the new P-T curve which was developed using Charpy shift data appropriately corrected for the material mixup, [MA91]. The technical specitication defines the cold shutdown condition as the reactor coolant temperature being less than (or equal to) 212'F and the hot shutdown condition is defined by a temperature greater than 212'F. Hydro-test in the hot shutdown condition requiers longer time to warm up the water and, in addition, hot shutdown must be scheduled as a critical path activity. Hydrotesting in the hot shutdown condition requires that the ECCS system must be operational, the safety system surveillance must be complete and the primary containment must be isolated. In the hot shutdown condition, leak detection is more difficult and the inspection conditions are more severe for personnnel. On the other hand, cold shutdown requires less time because the hydro-test can be done in parallel with other 70
I'h tf~
utage activities. Saving one day or even one half day of outage time results in a significant economic benefit to NMP-1.
5.2 Future Direction Niagara Mohawk should consider several actions for the future. The general direction should be to establish a strong plant specific surveill'ance program and avoid the use of overly conservative "generic" trend curves. If the NMP-1 and Oyster Creek data were shared, there would be sufficient data available to develop a plant specific trend curve. This approach can be
'implemented within the guidelines of RG 1.99(2) since the regulatory guide allows the adjustment of the hRT>>~ analytical model in cases where two or more credible surveillance data are vailable. Therefore, it is recommended that NMPC establish a cooperative program with GPU Nuclear as soon as possible.
With regard to the surveillance capsules, the B capsule should be pulled as soon as possible and tested. Serious consideration should be given to re-inserting a capsule which contains advanced dosimetry, temperature monitors, irradiated and unirradiated mechanical property specimens, and unirradiated fracture toughness specimen blanks. Fracture toughness specimen blanks were recently placed in the Oyster Creek re-insertion capsule. It would be best if the new capsule B target fluences were compatible with the Oyster Creek fluences.
In order to be certain of future regulatory acceptance, it is recommended that the limiting plate, adjustment factor be used 71
1
'n the next P-T curve update. It is essential that this approach be accepted by the NRC since it is important to establishing a plant-specific surveillance program. It is also suggested that work be undertaken to combine the NMP-1 and Oyster Creek surveillance programs and the existing data be used to establish a plant specific trend curve. It is likely that the current overly conservative model assumptions can be relaxed and future hydrotest and P-T operating windows opened. The NRC submittals should be coordinated and similarities of the two programs noted.
A submittal which requests NRC approval for combining the data
'ases shou'ld 'be prepared in the near future. An overall plan for the combined program which optimizes the withdrawal schedule should be prepared.

APPENDICES
APPENDIX A DESCRIPTION OF CAPSULES A'ND C'-2
APPENDIX A. 1 DESCRIPTION OF CAPSULES A'ND C'his appendix of the report describes the contents and layout-of Cap-sules A'nd C'. These capsules are considered to be advanced boiling water reactor (BWR) surveillance capsules since they contain mechanical behavior, temperature monitors, and dosimetry, which are not found in the currently used BWR capsules. The capsule inventory and assembly drawings are provided in Appendix A and the as-built photographs are provided in Appendix B. Details concerning the capsule design and fabrication of the contents are provided below.
Battelle established a subcontract with Metrology Control Corpora-
, .tion (MCC) to provide the radiometric monitors (RMs), helium accumulation fluence monitors (HAFMs), solid state track recorders (SSTRs), melt wires, and solid state track recorder-temperature monitors (SSTR-TMs). MCC entered into a contract with Westinghouse Hanford Company (WHC) for U.S. Department of Energy (DOE) dosimetry services of the National Reactor Dosimetry Center RDC) at the Hanford Engineering Development Laboratory (HEDL) and the helium mass spectrometry laboratory at Rockwell International Rocketdyne Division (RI-RD) (Mc87a). All other work described in this report was performed by Battelle.
Dosimetr In order to determine neutron exposure levels throughout the reactor vessel-geometry with a minimum uncertainty, it is necessary to employ a com-bination of rigorous analytical techniques and spectral dosimetry. In parti-cular, neutron transport calculations coupled with advanced neutron monitor sets located in surveillance capsules provide an improved approach to the determination of both axial and azimuthal exposure gradients within the pres-sure vessel. It is felt that this approach is superior to the current dosi-metry practice in which only wires of Fe, Cu, and Ni are included.
The design philosophy used for the dosimetry was to rely heavily on proven, time-tested technology which is why spectral RMs were used widely.
owever, as a backup, recognizing that the technology will advance over the xt decade, we have included HAFMs and SSTRs. The SSTRs are integrating A-3
I~
dosimeters which accumulate fission tracks throughout the irradiation.
Automated track counting is under development and counting methods will undoubtedly improve over the next few years. The HAFMs are wires composed of material with an appropriate (n, a) cross section. The helium accumulates in the material with increasing fluence and can be measured using any one of a variety of destructive chemical analysis techniques.
This section of the report gives a complete description of the advanced dosimetry fabricated for MCC by the NRDC at HEDL to provide two sets of dosimetry at three axial locations per set for Capsules A'nd C'. One set is to be exposed for -14 efpy years and the second set for -24 efpy years.
This advanced dosimetry has been prepared by the NRDC at HEDL with the assis-tance of RI-RD. The advanced dosimetry services provided are delineated in Table 1 of Appendix C. Assistance was. also provided by the NRDC to MCC in the preparation of purchase order specifications for the acquisition and fabrica-tion of the outer stainless steel (SS) and inner Gadolinium (Gd) shield capsules as well as the subsequent gA of the fabricated parts.
Capsule identification (etched on the outer SS surface) is as specified by Battelle. Anticipated fluence level exposures of -14 efpy and
~ ~
-24 efpy are denoted by A and C, respectively.* Bare and Gadolinium-covered dosimeters are designated by B and G, respectively; and the top, midplane, and bottom axial locations are indicated by 1, 2, and 3, respectively. A fourth identifying letter (A or B) was used when all the dosimetry for a single location could not be loaded into'a single capsule; e.g., capsules AG1A and AG1B. As additional examples of the numbering system:. AG1B indicates an "A" fluence exposure Gadolinium Covered - Top position - and second Capsule B with HAFM dosimetry; and CB3 would denote a "C" fluence exposure - Bare-Bottom axial location. In all instances, the first letter of the identifying number is located at the bottom end of the dosimetry capsule. The materials used and the 18 individual capsules are described in Appendix C. The dosi-metry holders and contents are shown in Appendix D. Each of the 18 capsules contains one or more of the following types of dosimeters: (1) RMs, (2) HAFMs, (3) SSTRs, and (4) SSTR-TMs.
Note: The Battelle designation for A and C are A'nd C', respectively.

A.2 Tem erature Monitors Two different types of passive temperature monitors (TMs) were supplied to observe irradiation temperature. A set of conventional melt wire (NW) TMs were used to cover the temperature range from 536 up to 598..F; These monitors are proven and time-tested and therefore are the primary source of temperature monitoring. A detailed description of these MW-TNs is provided below.
A second set of TMs were supplied which are based on the annealing properties of SSTRs. SSTR-TNs are a new and novel mean's of passively observ-ing irradiation temperature (Go79). A detailed description of these SSTR-TMs is provided in Section A.2.2 below. The advantage of these monitors is that
'they"are"'potentially"capable of providing an estimate of the average tempera-ture in the capsule. They have not yet been proven for reactor irradiations and the same fission track counting problems are experienced as with SSTRs.
However, these monitors were included as a backup to the melt wires since we ticipate that this technology will continue to develop over the next decade.
~ ~
A.2.1 Melt Wire Tem erature Monitors Eutectic materials with unique melting temperatures were included in Capsules A'nd C'. Composition and impurities greatly influence the melting
'temperature;'therefore, the materials used consist of purities of 99.9 percent or greater, so that the measured melting temperature is within at least +6 F of the recognized melting temperatures. The MWs were encapsulated in quartz tubing, evacuated and backfilled to approximately one atmosphere of helium pressure for optimum transfer of heat between the encapsulated NW and the outside environment. The MW-TMs included in Capsules A'nd C're listed in Table A-1 and photographs are provided in Appendix E.
The NW capsules were formed f'rom 0.24 inch outer diameter quartz tubing with 0.062 inch thick walls. To facilitate identification of these different NW temperature monitors, each MW was encapsulated in quartz tubing of a specific length as shown in Table A-l. After fabrication, the MW cap-sules were leak checked, pressure-tested and certified by con'ducting melt eriments. The certification test results indicated that all the MW ompositions melted within +2 F of the nominal value.

.Tem erature Monitors A number of limitations of MW-TMs can be overcome by using a new passive TM. This new passive TM provides for continuous monitoring of tem-rature with assigned uncertainties. It represents a novel, patented appli-ion of SSTR techniques [Go79]. Since tracks are annealed in SSTRs at elevated temperatures, the degree of annealing can be used to measure the in-situ temperature. Of equal importance is the nature of this SSTR-TM response, since it is based on track annealing and therefore, responds to the average time-temperature history that is experienced by the SSTR. Conse-quently, normal,.temperature excursions due to reactor operations are expected to make only small contributions to track annealing and the SSTR-TM will therefore furnish an accurate measurement of the in-situ temperature.
Fission fragments produce a narrow path of radiation damage in quartz glass, mica, and other SSTR materials. When chemically etched, a hole is produced along the damage path which can be seen under a microscope; this hole is called the fission track. All or part of the damage can be annealed out by heating the SSTR. This annealing, when carried out before the etching process, drastically modifies the length and/or diameter of the track when etching occurs. The amount of annealing is a function of time and temperature
[Go79, Ro80].
'n the case of quartz glass SSTRs, the annealing effect will reduce diameter of tracks produced by normally incident fragments, and will.
A-6
eliminate some of the tracks produced by isotropic incidence (exposures made with the source in contact with the SSTR material). In the case of mica SSTRs, the track length is reduced if damage has been partially removed by annealing.
The outstanding problem in the application of SSTR-TMs in power reactors is the lack of calibration data. MCC will be initiating an extensive calibration program within the next few months. Calibration curves for SSTR-TMs are obtained by observing the annealing characteristics of SSTRs.
Sets of quartz glass and mica SSTRs are prepared in the same way the SSTR-TMs were prepared for inclusion in the NMP-1 replacement surveillance capsule.
Both isotopic and normally incident fission fragment irradiations are used.
Subsets of these SSTRs are then heated in an oven at constant temperature for a given period of time. The oven must be well regulated so that stable temperatures are attained with an accuracy of at least +4 F. Upon withdrawal from the oven, the SSTRs are etched and subsequently scanned.
Calibration data are generated by repeating this process at different oven mperatures for different time durations. Preliminary calibration data for uartz glass and for mica have already been reported [Go79, RoBOJ.
Both quartz glass and mica are used for SSTR-TMs in Capsules A'nd C'. The pre-irradiation preparation of quartz glass and mica SSTR-TMs is discussed separately in Sections A.2.2.1 and A.2.2.2.
A.2.2.1 Pre aration of uartz Glass SSTR-TMs. The type of quartz glass chosen for SSTR-TM applications in reactor surveillance should possess a very low concentration of fissionable impurities. Consequently, a high purity quartz glass, namely Supersil, has been used. Supersil quartz glass was supplied by Amersil Company, Inc., Hillside, New Jersey.
The Supersil quartz glass was cut into a disk shape, 0.178 inches in diameter by 0.06 inches thick. Both surfaces of the disk were then mechani-cally polished to remove scratches and imperfections. A final surface polish was obtained by etching in 49 percent HF at 70 F for 120 minutes.
The polished Supersil quartz glass was then cleaned by rinsing in the following solutions in the order given: (1) Palm Olive Soap Solution,
2) distilled water, (3) double distilled water, (4) Ultrex BN nitric acid,
, finally, (5) double distilled water. This cleaning process was used both A-7

A.2.2.2 Pre aration of Mica SSTR-TMs. The type of mica chosen for SSTR-TM applications in reactor surveillance should also possess a ve~ low concentration of fissionable impurities. To this end, mica from India, sup-plied by The Perfection Mica Company, has been used. The mica was first pre-annealed in an oven for about 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months at 1076 F. It was then pre-etched in 49 percent HF 70 F for about 18 hours2.083333e-4 days 0.005 hours 2.97619e-5 weeks 6.849e-6 months . When placed under a microscope, resi-dual fission fragment tracks are seen. The mica with a low density of tracks was selected. It was then cleaved to thicknesses of about 0.003 inches.
Disks, 0. 178 inches in diameter, were punched from the freshly cleaved mica.
Mica'STR-TMs were cleaned by the same procedure used for the quartz glass. This cleaning process is important just prior to encapsulation, in order to rid the mica of transuranium or other actinides that may produce undesirable fission fragment tracks while being exposed to neutrons in the ctor.
A.2.2.3 SSTR-TM Fission Fra ment Irradiation. Prior to use, the SSTR-TMs must be exposed to fission fragments. A uniform source of 252Cf was
.used for the irradiation. Two types of, fission fragment exposure, isotropic and normally incident, were used. The isotropic exposure is performed by placing the 'SSTR-'TM in firm contact with the spontaneous fission fragment source. Normally incident exposures were obtained in a vacuum chamber. There was approximately 2.2 inches between the SSTR-TM and the spontaneous fission fragment source. For the isotropic exposures, a 252Cf spontaneous fission fragment source having a diameter of 0.25 inches', on a stainless steel disk 0.75 inches in diameter, was used. The source had a very thin gold coating.
On 1-29-86, this source had an activity that produced 9230 tracks per minute per square centimeter in mica placed in direct contact with it. A 252Cf source about 1/8 inch in diameter was used for exposures in the vacuum chamber. On 1-31-86, an exposure gave a track density for normal incidence of 60.1 tracks per minute per square centimeter. The statistical accuracy of oth measurements is 2.7 percent.
A-8
+1IF A.2.2.4 Fission Fra ment Irradiation of uartz Glass SSTR-TMs. One -
side of the quartz glass SSTR-TM was irradiated isotropically with fission fragments and the other side was irradiated with normally incident fission fragments. Estimated track densities for the isotropic and normal irradia-tions, respectively, are given in Table A-2. Two such quartz glass $ STR-TMs were prepared for each capsule. Isotropic exposure data from the mica SSTR-TM are given in Table A-3.
A third quartz glass SSTR-TM was prepared for each capsule as described earlier, but was not irradi'ated with fission fragments. One surface of this third quartz glass SSTR-TM is used to assess fission fragment track background induced during the reactor surveillance irradiation. The other surface was placed in firm contact with a 23BU deposit to form an SSTR neutron dosimeter for the'reactor surveillance irradiation. This SSTR neutron dosi-meter will provide fission fragment tracks that are formed throughout the entire course of the surveillance irradiation. Consequently, this type of SSTR-TM provides information on the time-temperature history of the surveil-
~ ~
nce irradiation.
~ ~
After being cleaned, the
~
SSTR-TMs were loaded into capsules AB2 and CB2 as shown in Figures A-1 and A-2.
A.3 Char V-Notch S ecimens The types-and number of Charpy specimens in the reinserted capsules were summarized in Table A-2. Niagara Mohawk decided to weld reconstitute the Charpy specimens prior to reencapsulation. The specimens can be tested in this configuration or miniature Charpy specimens could be machined in the future when the capsules are withdrawn. Battelle has developed a miniature Charpy test in which 16 miniature specimens can be machined from one conven-tional specimen.
A total of 24 Charpy V-notch (CVN) specimens (12 base, 12 weld) were reconstituted for inclusion in Capsule C'. A total of six CVNs were recon-stituted for inclusion in Capsule A'. The specimens were stamped on the ends with the appropriate F.A.B. code designation. The original F.A.B. code
'dentification was used with an additional letter "A" or "B" to designate a onstituted specimen. The specimen identifications and locations within the packets are given in the Appendix A specimen inventory drawings.

A.4 Miniature and Conventional Tensile S ecimens The types and number of tensile specimens in Capsules A'nd-C'ere summarized in Table A-2. In cases where conventional tensile specimens were already tested, miniature specimens were machined from the broken halves. The Battelle proprietory specimen design is shown in Appendix A [Ma86]. A total of two miniature tensile specimens (base) were included in Capsule A'nd eight miniature tensile specimens (four base, four weld) were included in Capsule C . The miniature tensile specimens were numbered consecutively from one to 10. The conventional tensile specimens retained their F.A.B. code designations. The specimen identifications and locations are shown in the Appendix A inventory drawings.
A.5 Ca sule Desi n and La out Surveillance capsule packet inventory drawings were prepared for the o reinsertion Capsules A'nd C'nd are given in Appendix A. The inven-ories include all specimens shown, in Table A-2 and the recommended dosimeters and temperature monitors. Packet fabrication drawings were also prepared that show specimen, dosimeter, temperature monitor, and spacer locations and dimen-sions in each capsule. GE fabricated the spacers, packets, baskets, and lead tubes. The drawings indicate the specimen F.A.B. code designations and the as-built photographs show specimen by specimen agreement with the fabrication drawings.
The dosimetry was carefully oriented and spaced to avoid neutron field perturbations which would affect the data. The dosimetry was also located so that the axial flux profile can be measured. Good heat transfer is insured by tight specimen packing and a helium backfill in each packet.
A.6 Archive Materials The length of these planned irradiations, namely Capsule "A" for 14 efpy and Capsule "C" for 24 efpy, make it mandatory that archive dosimetry nd TM materials be retained by Niagara Mohawk. Experimental results from wer reactor irradiations can sometimes by inconsistent or hard to resolve.
Cf It is
~
essential, therefore, that these archive materials be available as a
~
contingency should problems arise with the experimental dosimetry results.
With these materials, calibration experiments can be repeated and, if n'eces-sary, neutron benchmark irradiations can be. conducted. Should definitive follow-on experiments of this type be needed, the availability of these archive materials can be a crucial factor in the success of the dosimetry analysis. To this end, archive materials, identical to those used in Cap-sules A'nd C'ave been provided to Niagara Mohawk. Tables A-4 through A-7 summarize the supplied archive materials for RM neutron dosimeters, SSTR neutron dosimeters, MW-TMs and SSTR-TMs, respectively.

c. 2 sets of fissionable, vanadium encapsulated, Gd covered RMs; each set consists of one each of: U-235, U-238 and Np-237 oxide wires.
d. 2 sets, of fissionable, vanadium encapsulated, "bare" RMs; each set consists of one each of: U-235 oxide wire.
Solid State Track Recorder (SSTR) Fluence Monitors
e. 2 sets of Gd covered SSTRs; each set consists of one each of: U-235, U-238 and Np-237, (fission deposits on solid state track recorder backing material with mica SSTRs).
2 sets of "bare" SSTRs; each set consists of one each of: U-235, (fission deposit with mica SSTR).
Helium Accumulation Fluence Monitors (HAFM
/
g. 6 sets of non-fissionable, Gd covered HAFMs; each set consists of one each of Be (pieces wr apped in Al)*, Cu, Co/Al (or Al), Ni and Fe metal"wires.
h. 6 sets of non-fissionable, "bare" HAFMs; each set consists of one each of Be (pieces wrapped in Al), Cu, Co/Al (or Al), Ni and Fe metal wires.
Thermal Monitors TMs)
i. 2 sets of melt wire (MW) TMs; each MW-TM set consists of five melt wires, each of which is contained in a quartz capsule.
Material will be in the form of one or more small pieces of Be metal, wrapped in aluminum with a nomial effective package diameter of -20 to 40 mils and length of less than 0.25".

kt 4 TABLE 1 (Cont'd)
Solid State Track Recorder (SSTR)-THs
j. 2 sets of TMs; each set consists of 3 quartz and 2 mica pre-irradiated SSTRs wrapped in Al. Each set placed in a Gd cover (with other dosimeters) in a SS dosimetry capsule.
Oosimetr Ca sule Fabrication
k. 6 bare and 12 Gadolimium lined stainless steel holders were loaded and assembled.
1. The SS capsules were back-filled with high purity (dry) Argon** prior to welding and were subsequently leak checked by immersion in near boiling water (that has been boiled to remove air bubbles). X-Rays of the loaded holders were also taken.
QA and Oocumentation
m. A QA data package including the "as-built" description and documentation of all dosimeters and encapsulation containers is provided in the Appendices.
Helium was not used because it could adversely (by absorption or diffusion) bias the interpretation of the HAFH monitor results.

2) It is recommended the Gd capsules actually be cracked open (i.e., use "nut cracker" on lower end of capsule) the reason for this is that several of the dosimeter packets are quite a tight fit and possibly would be damaged in the attempt to pull them out of the capsule or to cut open the bottom and push them out.
3) No Al material should be discarded without close observation as to whether it is simply spacer material of wrapped dosimeter material. Fe gradients are wrapped individually and though marked Fe could be mistaken for spacer material. Both bare spectral Co/Al and Fe/235-U are wrapped in Al and are unmarked and could therefore be mistaken for spacer material.

2) It is recommended the Gd capsules actually be cracked open (i.e., use "nut cracker" on lower end of capsule).
The reason for this is that several of the dosimeter pockets are quite a tight fit and possibly would be damaged in the attempt to pull them out of the capsule or to cut open the bottom and push them out.
3) No Al material should be discarded without close observation as to whether it is simply spacer material or wrapped dosimetry material. Fe gradients are wrapped individually and though marked, Fe could be mistaken for spacer material. Both bare spectral Co/Al and Fe 235-U are wrapped'n Al and are unmarked and could therefore be mistaken for spacer material.

K.1 30 DEGREE CAPSULE DATA K-2
<ap K. 1. 1 Dosimetry Table K-1 contains the results of the analysis of the dosimetry wires from the 30-degree position surveillance capsule.
The wire identifications, measured radionuclide activities (in dps-mg '), and wire compositions are tabulated. The measured activities have been decay corrected to November 30, 1984. The composition of the Cu and Ni wires was taken from Reference
[HI69]. The percent Fe for the iron wire was taken from Reference [LO84].
As indicated in Table K-l, the two Ni wires, Pl-Ni.l and P2-Ni.2, are listed for packet P1. This is because packet Pl contained two Ni wires but no Cu wire. Both Ni wires were anlayzed witht he results listed. For the Co-58 measurement on he Ni wires, no Co-58 activity was measured due to the long decay time following removal of the capsule from the reactor and the relatively short half-life of the isotope (70.8 days). The values which are listed in the table for Co-58 are upper limits for the-specific activity based on detection limits.
K.1.2 Fluence Calculation To accurately determine the neutron flux at the capsule and in the pressure vessel wall, the neutron spectrum must be calculated. The spectrum was calculated for the 300-degree capsule by analyzing the octant adjacent to the capsule, and the results were reported in Reference [ST84]. An analysis was performed to determine if the assumption of octal symmetry for he 30-degree capsule is reasonable. This assumption precludes the need to calculate the spectrum for the 30-degree capsule.

Niagara Mohawk supplied bundle-cycle-exposure data for the core octant adjacent to the 30-degree capsule position. We compared the ratio of the bundle-cycle exposure to the core-average-cycle exposure for the appropriate geometrically symmetric bundles in the outer core region. Most of these ratios were within a few percent. Therefore, the assumption of octal symmetry is reasonable and results in a small error in the effective cross sections.
Calculations of the flux and fluence were made using the DECAY code. The reactor power history was supplied in a private communication'C084]. The effective cross sections and nuclear constants were reported in Reference [ST84].
The E>0.1 MeV and E>1 ' MeV full power flux and fluence calculated from initial startup to March, 1979, are given in Tables K-2 and K-3 respectively. For each of the dosimeter wires, the average of the flux and fluence was determined by averaging over all the Fe and Cu wires. It was not possible to estimate the flux for the Ni dosimeters, since the Co-58 activity was not detectable because of the long decay time following removal of the capsule.
The accuracy of the fluence values calculated is approximately +5 percent accuracy, uncertainties in neutron spectrum and spectrum-averaged cross sections result in the larger variances in the computed flux and fluence values.

.2.1 Anal tical Method The determination of the neutron flux at the capsule, and subsequently in the pressure vessel wall, requires the completion of thre'e procedures. First, the disintegration rate of the product isotope per unit mass of the flux monitor must be determined. Second, in order to find a spectrum-averaged reaction cross section at the capsule location, the neutron energy spectrum must be calculated. Third, the neutron flux at the capsule must be found by calculations involving the counting rate data, the spectrum-averaged cross sections, and the operating history of the reactor.
The energy and spatial distribution of neutron flux in the reactor were calculated using the DOT 4.3 computer program '~~.
OT solves the Boltzmann transport equation in two-dimensional geometry using the method of discrete ordinates. Balance equations are solved for the density of particles moving along discrete directions in each cell of a two-dimensional spatial mesh.'nisotropic scattering is treated using a Legendre expansion of arbitrary order.
The two-dimensional geometry that was used to model the Nine Mile Point-Unit 1 Reactor is shown in Figure K-1. As seen, there are 16 circumferential meshes and 66 radial meshes. The capsule includes circumferential meshes 6 and 7 and radial meshes 54 and 55. Third order scattering was used (P~) and 48 angular directions of neutron travel (24 positive and 24 negative) were used (S8 quadrature). Neutron energies were divided into 47 roups with energies from 17.3 MeV to 10 eV. The 47 group

k structure is that of the RSIC Data Library DLC75/BUGLE 80 and neutron absorption, scattering, and fission cross sections used are those supplied by this librar'y. The core shroud is Type 304 stainless steel. The capsule is also modeled as a solid piece of Type 304 stainless steel. The reactor pressure vessel wall is SA302B steel. The reactor core was mocked up as homogenized fuel and water having the densities found in the operating reactor. The water in the core region has a density consistent with saturation conditions at the operating pressure of 1050 psia and a core-averaged steam volume fraction of 0.30 ~
The water in 'the downcomer has a density consistent with an inlet subcooling of 23 Btu/pound. Finally, the fuel was a source of neutrons having a U-235 fission energy spectrum. The relative ower in the assemblies nearest the capsule, during he interval the capsule was in the reactor, is shown in Figure K-17'~~"'. A plane view of the Nine Mile Point Reactor physical geometry at the core midplane is shown in Figure K-1 and because of symmetry includes only a 1/8th segment.
The neutron spectrum at the capsule center, as calculated by DOT, is shown in Figure K-2. Also shown for comparison is the fission spectrum. The fission spectrum was normalized to contain one neutron/cm~/sec above 1.0 MeV. The neutron spectrum at the capsule center was normalized to contain the same flux as the fission spectrum at 1.0 MeV energy. As can be seen, the capsule spectrum is considerably harder than the fission spectrum. This is caused by neutron travel through water.

Based upon the fluxes calculated by DOT at radial meshes 54 and 55 and circumfenential meshes 6 and 7 (the meshes used to represent the capsule and the region in which the flux monitors were placed), effective cross sections a~ (E > 0.1 MeV) and G~ (E
> 1.0 MeV) defined as:
cr(E > E,)
0 (E) dE E,
were calculated for iron, nickel, and copper. The results are shown in Table K-4.
Other nuclear constants needed in the third step of the flux-finding procedure are given in Table K-5.
In the third step, the full power flux at the capsule location is determined from the radioactivity induced in the monitor foils, the effective cross sections calculated for the monitor elements, and the power history of the reactor during capsule exposure. The fluence at the capsule is then calculated from the integrated power output of the reactor during the exposure interval using the following equation:
) (E > E ) = A/ [Na(E > E ) C]
This equation was used to find fluxes based on the measured surveillance capsule activations. The time intervals were taken as one month each and a time integrated relative power value for each month was used for the fractional power level values.
Calculations of the flux and fluence were made with the DECAY code. The reactor power history was supplied in a private communication'

The surveillance capsule was located at the 300-degree azimuthal position at approximately the core midplane position and at 7/16- inch from the inner pressure vessel wall. This capsule was in the reactor for" 2913 equivalent full power days or about 7.98 equivalent full power years. The Nine Mile Point Nuclear Generating Plant design thermal output is 1850 MW.
The neutron monitor wires from Charpy packets P7 and P8 wee counted to determine their specific activity. The recommended ASTM procedures ~~~" ~~"'~'" As~"'~' were followed in determining the specific activity of the wires. Each dosimeter monitor consisted of an approximately 4-inch length of wire which was rolled into a small coil for counting. The count rate was determined for each wire ~ The fast flux and fluence calculated using the count rate therefore represented an average over the 4-inch length of that wire. The E > O.l MeV and E > 1.0 MeV full power flux and fluence calculated from initial startup to March 1982 are given in Table K-6 and Table K-7., respectively, for each f the dosimeter wires along with the average of the flux and fluence derived from each wire and the average values for Fe, Cu, and Ni. In addition, the average values of the results for Fe and Cu are given. The Ni results were not used because the very short half life makes its results dependent on only the latest operating history.
Using the average fluxes of 3.32 x 10 n/cm /sec for E > 0.1 MeV and 1.90 x 10'/cm'/sec for E > 1.0 MeV, the fluxes at full power at the inside of the pressure vessel wall, at 1/4 T and at
k tf A4
3/4 T directly behind the capsule (300-degree orientation) and at the maximum position (285.66-degree orientation) were calculated.
The flux results are tabulated in Table K-8. The end of life (EOL) fluences were also calculated and tabulated in Table K-8 assuming a reactor pressure vessel lifetime of 40 years and the reactor operated at 80 percent of full power. The fine mesh and time integrated relative power values shown in Figure K-8 for each fuel assembly was used in the DOT 4.3 code to generate the values in Table K-8. A plot of neutron flux (E > 1.0 MeV) as a function of azimuthal angle (in degrees) is shown in Figure K-3.
The fluence values at the maximum position for inner vessel wall, 1/4 T and 3/4 T are plotted as a function of time in equivalent full power years (EFPY) for the Nine Mile Point pressure vessel in Figure K-4. The lead factor, ice., the ratio of the flux (E >
~
1.0 MeV) at the surveillance capsule to the largest flux (E > 1.0
~
MeV) received by the vessel wall at any azimuthal location, is approximately 0.68 (1.90 x 10'/2.80 x 10') at the vessel surface.
This result indicates that the flux at the capsule actually lags the flux at certain vessel wall positions. The lead factors at the pressure vessel 1/4 T and 3/4 T positions were calculated to be 0.99 (1.90 x 10 /1.91 x 10 ) and 3.70 (1.90 x 10 /5.14 x 10 ),
respectively.
The accuracy of the fluence values generated is estimated to be +20 percent. Although specific activities of fluence monitor wires can be determined to +5 percent accuracies, uncertainties in neutron spectrum and spectrum averaged cross K-16

The rate of displacements per atom was also calculated using the cross sections for displacement available with the DETAN code. Table K-9 shows calculated values of displacements per atom per second at full power in the pressure vessel wall behind the capsule and in the pressure vessel wall at the angle of peak fluence in the wall. Table K-9 also shows calculated values of displacements per atom at these same positions in the wall for 7.98 effective full power years of operation (to time of

1.0 INTRODUCTION
1.1 Pur ose An analysis was perf1ormed to establish best estimate values for the RT~~ and a, term used in Regulatory Guide 1.99 (Rev. 2) calculations for the Nine Mile Point Unit 1 (NMP1) beltline plate and weld materials. Sufficient data are not available to determine the RTgp~ in strict conformance with the current ASME code rules. In the case of the weld metals, only three unirradiated Charpy tests were conducted at 10'F.
Charpy transition behavior data are available for the plate materials, however, there are no drop weight data for all of the beltline materials except for plate G-8-3/G-8-4. The methodology used was first described in {MA85] and was specifically designed to address ,the problem of RTz~
determination in cases where there are not sufficient data available to satisfy the ASME code requirements. The results of these analyses are presented in Sections 2.0 and 3.0 of this report. Conclusions and recommendations concerning the use of these data are provided in Section 4.0.

2. 0 WELD MATERIAL ANALYSIS The objective of the weld material analysis is to calculate a statistically meaningful o, for the beltline welds which can be used in the Margin term of the Regulatory Guide 1.99-Rev. 2 (RG1.99(2)) model. Also, the initial RTpT of each of the beltline welds and the surveillance capsule material was calculated using Manahan's statistically based calculative procedure [MA85b].
The only unirradiated fracture behavior data available for the weld materials is Charpy data at 10'F [MA90, BY90]. Irradiated data for the surveillance capsule material, designated weld W5214/5G13F (wire heat no./flux lot no.), is also presented in Reference [MA90]. Both the irradiated surveillance data and the unirradiated data for each weld were used to calculate o, and the RTpT of each beltline weld. As described in Reference [MA90], the base metal Charpy specimens were machined with their long axes rallel to the plate rolling direction. Therefore, the crack plane is oriented transverse to the material grain (L-T orientation). The weld specimen long axis was machined transverse to the weld direction. Since there are no microstructural data available for the welds, it 'has been assumed that the material is isotropic and no correction for grain orientation was made in the RTgpT analysis . Unl ike base metal pl ates, the weld material generally does not exhibit grain orientation effects and, therefore, the Charpy specimen orientation is not critical for weld.
materials.
2.1 Weld W5214 5G13F Anal sis Weld W5214/5G13F is the surveillance capsule weld.
Unfortunately, this weld was not made using the same wire or flux as the beltline welds. However, the weld materials were manufactured by the same suppliers for the beltline materials (RACO g3 wire, Arcos B5 flux) and the Cu and Ni content is representative of the beltline weld 1248/4M2F. [BY90, MA90]
(Data on the Cu and Ni content of the other two beltline welds L-9
is not available.) Therefore, it has been assumed that the capsule weld material is similar to the beltline welds in terms of its mechanical behavior trend.
The irradiated Charpy data for the capsule weld material was analyzed using the SAM McFRAC code [McFRAC).
The SAM McFRAC code has been QA verified in accordance with The Pennsylvania State University, Nuclear Quality Assurance Program. This code is based on a non-linear, least squares, regression analysis using the Weibull statistic. The Weibull statistic has been shown to be the correct statistic for analysis of fracture data by considering the microstructural mechanisms involved in the fracture of ferritic, pressure vessel steels [MA85a].
The confidence bands are measures of "the goodness of fit" and do not indicate the classical 954 statistical error spread. This uncertainty must be analyzed using conventional statistical methods. However, the McFRAC confidence intervals are used to measure confidence in the fit of a particular data set as well as the inherent scatter due to the fracture process. These error bands must be calculated, particularly, for sparse data sets, because in many cases the ability to fit sparse data drives the uncertainty. The McFRAC analysis for the irradiated capsule weld is shown in Figure 2-1.
The o, term is the uncertainty in the initial RTgpy determination.Section III of the ASME code requires that, both drop weight tests, to determine the NDTT, and Charpy tests be performed. The NDTT temperature deter-mined by following ASTM E-208 is the RT>> provided that, at 60'F above the NDTT, at least 50 ft-lbs. of energy and 35 mils lateral expansion are obtained in Charpy speci-mens with crack planes oriented in the weak direction.
The weak direction is transverse to the direction of maximum working (T-L orientation) for base metal.

11 Therefore, cr, should reflect the uncertainty in either the drop weight test or the Charpy test depending on which test ultimately determined the RTDz. As described below, Charpy data are used to determine the Ropy and there fore, a, is determined by estimating the uncertainty in temperature at the 50 ft-lb. energy level.
Based on examination of the confidence in the McFRAC fit at 50 ft-lb., cr,(fit) = 14.0'F. Analysis of the statistical 954 confidence interval for the data yields cr,(experimental) = 12.5'F. Based on examination of the LWR data base, Odette [OD86] has shown for welds that, cr,(data base) = 18.0'F.
The uncertainty for weld W5214/5G13F is higher than that of the LWR data base because of the sparsity of data in the transition region. Additional testing would reduce o,(fit) and e,(experimental). Therefore, the final o, was determined using a weighted average of plant specific and generic data conservatively assuming there were only ten data points in the data base analyzed by Odette, to yield cr, = 17'F. This value for cr, is recommended for use in [RG1.99] Margin term calculations for all of the beltline weld materials.
Many operating power plants were built when current regulations concerning establishment of the initial RT~~
were not in force. Zn many cases, insufficient drop weight and Charpy data are available to determine the RT~~ in accordance with the current Section XII of the ASME code. Prior to 1972, the ASME code recpxired that the average of three Charpy specimens be at least 30 ft-lb. at a designated temperature, with no single impact energy less than 25 ft-lb. These are the rules which were used for the vessel. The NRC Branch Technical Position, MTEB 5-2, contains a procedure for estimating the RT~~ based on generic data. However, this approach
12 is overly conservative for some materials and does not take advantage of the use of limited unirradiated nor irradiated data in the analysis. GE also has a generic model which is based on a transition region slope of .5 ft-lb./'F. However, this model, like the NRC model, is generic and lacks statistical rigor.
Neutron irradiation of pressure vessel materials causes:
an increase in the 30 ft-lb. transition temperature
2) a lowering of the upper shelf
3) . a decrease in the slope of the transition region [OD86]
In addition, Odette has shown that the transition region occurs over an approximately constant interval of temperature. Odette pointed out that this fact, in concert with a continuous decrease of upper shelf energy (USE), requires that the 'transition region slope must decrease with irradiation. The average value of the transition temperature range, 6T~, is about 200 F +45 F for welds. These data, along with Odette's yield strength model, can be used to provide an accurate estimate of the RTQ7 of the beltline weld materials assuming that the NDTT occurs at a lower temperature than the temperature at which three Charpy specimens would exhibit 50 ft-lbs. of energy minus 60. This assumption is accurate for most pressure vessel materials because the NDTT is expected to occur at or near the brittleness transition region near the onset of the lower shelf. Analysis of the LWR ASTM A533B data base substantiates this assumption. In the 23 cases analyzed, the NDTT was less than or equal to the RT~~. In 15 out of 23 cases, the RT~~ was determined from the Charpy data. The average difference between the actual RTgp~ and the RTgp7 estimated using the Ref erence [ MA85 ] approach
I I
13 was 8'F for welds and 10'F for base metal. The average net deviation is about 4.3'F for plate and weld. A similar analysis was conducted for ASTM A302B data. In all of the 17 cases analyzed the NDTT was less than or equal to the RT~T. The RTgpT was determined from Charpy data in 13 of the 17 cases. The average between the ASME code determined RT~T and that determined using Reference
[MA85] was 8', and the average net deviation was 4.4'F for the base metal.
Given these facts and observations, the approach to RTgp7 determination is to determine a temperature, T50T (for T-L orientation), at which three Charpy specimens would be expected to yield greater than 50 ft-lbs of absorbed energy. The T50T is determined by analyzing the uncertainty in the Charpy data in the transition region.
The Tzo~ temperature is defined as the, temperature at which the mean Charpy curve minus 50 ft-lbs equals 20E.
Once the T50~ temperature is determined, the RTgp7 is taken to be T50~'minus 60'F. This basic approach was used for both plates and welds. In the weld analysis, additional steps were followed since full Charpy curves were not available for the unirradiated welds. The procedure used to calculate the RTN07 for the Oyster Creek welds is as follows:
~Ste 1 Using Odette's yield strength model [OD86],
calculate the unirradiated upper shelf energy (USE ).
~Ste 2 Draw a horizontal line at the USE'evel and pass a line through the unirradiated data which intersects the USE'ine such that the transition region spans 2004F. Verify the reasonableness of the slope by comparison with the irradiated transition region slope.

level (6T>Q) and compare with the ST3Q obtained above and with the RG1.99(2) model prediction.
For weld 85214/5G13F, the unirradiated USE was calculated to be: USE' 128 ft-lb. The results of the Step 2) graphical analyses are presented in Figure 2-2.
As discussed in Reference [OD86], the entire irradiated Charpy curve can be predicted knowing only the change in yield strength due to irradiation and the unirradiated Charpy curve. This procedure was woxked in reverse using the irradiated Charpy curve and the change in yield strength. The measured slope of the irradiated Charpy curve is 0.539 ft-lb/'F which is in good agreement with the irradiated data as shown'n Figure 2-2. The calculated slope of the unirradiated transition region is 0.645 ft-lb/'F, which is slightly larger than the irradiated curve, as expected.
The third step of the RTQT analysis calls for an assessment of the statistical 954 confidence band (2u E )
for energy measurement at the 50 ft-lb. level. Two separate calculations were performed. The first approach uses the 2'ariation in energy at the 50 ft-lb. level.
This results in: 2aE(fit) = 13.5 ft-lb. The second approach consists of an assessment of the 954 confidence in the experimental data. This approach yields:
2v~(experimental) = 12.0 ft-lb. The procedure defines 2@~ as the larger of 20E (fit) and 2'~ (experimental),
with the lower bound being 10 ft-lb. Therefore, for weld W5214/5G13F: 2aE = 10 ft-lb.

16 Since the three data points for weld W5214/5G13F were over 50 ft-lb., the RT~z is taken to be:
RT~~ (weld W5214/5G13F) = 10'F - 60 F = -50'F. In order to demonstrate the validity of the RT~~ approach, the Reference [MA85) procedure was followed. In accordance with Step 4, three Charpy specimens with energies in excess of 50 ft-lb. would be expected at a test temperature of 20'F. Therefore, the RTz~ using this approach would be -40'F, which is in close agreement and slightly conservative when compared with the measured Charpy data.
2.1.3 Summar of Findin s Based on the statistical analysis presented above, a value of o> of 17'F is justified for the beltline welds. An initial RTgQ7 of -50 has been established for weld W5214/5G13F. Also, unirradiated Charpy indices have been established for the capsule weld material. These data are summarized in Table 2-1..

3. 0 PLATE MATERIAL ANALYSIS 1
In the case of the base metal plates, full unirradiated Charpy curves are available for each beltline plate. The surveillance capsule base metal'pecimens were fabricated from plate G-8-1
[MA90).
It is possible to calculate a o> for each plate as was done for the irradiated weld. However, a value of a, = 0 is recommended for all the plates except G-8-3/G-8-4. The o< for G-8-3/G-8-4 is taken as 2'F since experimental data was used and conventional ASME test practices followed. Justification of u, = 0 for the remaining plates comes from the fact that Manahan's RTz~ determination is generally conservative, the T)pg is taken to be a point where the ASME Charpy criterion is expected to be satisfied with high confidence, and the L-T to T-L orientation correction was taken to be 24 F which is 4 F higher than that recommended in Branch Technical Position MTEB 5-2. The value of cr, = 2 was obtained by taking the Ropy found using Manahan's method, subtracting the ASME determined l
Ropy and dividing by 2 ( rounding up ) . The resu ts of the o',
analysis are given in Table 3-1.
The RTgpz was determined in a similar manner as described in Section 2.1.2, except that the temperature at which 50 ft-lb. of energy would be obtained in three Charpy specimens could be determined directly from the Charpy curves. First, the unirradiated data was- fit using the SAM McFRAC code.
Then, the 954 confidence interval in energy (2cr<) was determined using the more conservative value of either the fit uncertainty at the 50 ft-lb level (2cr~(fit)) or the deviation of the data from the mean in the transition region (2v~
(experimental)). If both of these measures are less than 10 ft-lbs, then 10 ft-lb. was taken as the 2cr< value. Otherwise, the larger of 2az(fit) or 2vz(experimental) was used. The 10
20 ft-lb. uncertainty was judged to be a reasonable and conservative value based on observation of many data sets in the LWR data base.
After 2a'~ was determined, the temperature, T><< (L-T orientation), at which three Charpy specimens would exhibit 50 ft-lbs of absorbed energy was determined. This temperature was taken to be the temperature at which the mean Charpy curve minus 50 ft-lbs. equals 2cr~. Once, the T><< temperature is determined, the RTzz (L-T) is taken to be T><< minus 60'F.
The Charpy specimens tested for the plate materials had an L-T orientation. The ASME code requires testing using the T-L orientation because it is the limiting orientation.
General Electric recommends adding 30'F to the RT~~ obtained C
using L-T specimens. Similarly, Branch Technical Position MTEB 5-2 recommends adding 20 F. Analysis of the EPRI data base presented in'MA89] indicates that 30'F is appropriate.
Therefore, in the absence of material specific data, MPM Consulting recommends using 30'F. However, reference [MA90]
reported an L-T to T-L Charpy curve transition of 24'F at the 30 ft-lb. level. Therefore, based on the material specific data, the L-T to T-L correction used herein was 24'F. The results of the analysis are summarized in Table 3-1 and the McFRAC fits are given in Figures 3-1 through 3-6.

The surveillance welds for Oyster Creek and NMPl are identical. Also, the beltline welds 1248/4M2F and 86054B/4E5F are the same fox the two plants. The RT+z results for the surveillance weld and weld 1248/4M2F were exactly the same for the two plants, and the RT+zs for weld 86054B/4E5F differed by only 8'F using the [MA85] procedure. Thus, the agreement for the two independent calculations was quite good. The weld RT~zs are also consistent with the generic RT~z value of -56'F reported in
[BY90].
In addition to firmly establishing the RT~z for all of the beltline materials, a further benefit of this analysis has been the determination of the surveillance weld T>Q and USE. Up to the resent, the weld surveillance data has been of little value since
0 29 the 4T>0 and 4USE cannot be calculated. However, the calculations reported herein have determined the unirradiated Tzo to be -32'F and the USE to be 128 ft-lb.
In the future, consideration should be given to obtaining a cooperative agreement with GPU Nuclear to share surveillances data for NMP1 and Oyster Creek. These two units are of the same design and vintage and have several identical materials. The two data bases can be combined to yield accurate plant-specific trend curves. Also, it would be desirable in the future to anneal the surveillance weld material and directly measure the Charpy properties of the material. These data could be used to verify the calculations and possibly reduce the uncertainty in the models.
