COMMONHEALTH EDISON C0t@ANY RESPONSE TO NRC REQUEST FOR ADDITIONAL INFORMATION l DATED DECEMBER 2, 1992 Re g elt E : Provide the basis (mechanistic and statistical) for not including in your analysis unirradiated data with stress relief times greater than 35 hours4.050926e-4 days 0.00972 hours 5.787037e-5 weeks 1.33175e-5 months .

MoongE: A B&W review of vessel fabrication records showed that the maximum !

time that any B&H-fabricated PHR reactor vessel, fabricated using HF-70, was stress relieved is 35 hours4.050926e-4 days 0.00972 hours 5.787037e-5 weeks 1.33175e-5 months , hence data beyond 35 hours4.050926e-4 days 0.00972 hours 5.787037e-5 weeks 1.33175e-5 months was considered irrelevant. In the case of Zion Units 1 and 2,-the stress relief times wore 23 hours2.662037e-4 days 0.00639 hours 3.80291e-5 weeks 8.7515e-6 months and 31 hours3.587963e-4 days 0.00861 hours 5.125661e-5 weeks 1.17955e-5 months respectively. The rationale for this approach is discussed in I detail in BAH-2100, and the appropriate paragraphs are extracted and presented as follows:

"LYAJyation of Initial PJggy_h All the initial value RTNDT data for Mn-Mo-N1/Linde 80 weld metals except those fabricated with weld wire 72105 are presented in Tables 14-1 and 14-These data are presented in Figure 14-1 and show that the general population ,

of the Mn-Mo-Ni/Linde 80 initial RTNDT values lie betweer: -50 and +30F.

These data are for materials with a range of strest-relief times. Typically, the toughness values of these materials exhibit a low sensitivity-to stress-relief times.

The initial RTNDT data for weld metals fabricated with weld wire 72105 are ,

presented in Table 14-3. These data are also identified as to source and stress-relief time. The data are presented in Figure 14-2 along with the general population of the Mn-Ho-N1/Linde 80 initisi RTNDT values from Tables 14-1 and 14-2 and show that the weld metals fabricated with weld wire 72015 HF-70 and WF-209-1, have initial RTNDT values that.11e between Of and +120F and overlap the general Mn-Mo-N1/Linde 80 date in the temperature range of O' to 30F. The range of the RTNDT data of the 72105-weld metals is nearly twice ihat of the' general population of Mn-Mo-Ni/Linde 80 weld metals. This variability is attributable to the 72105 weld metals having a unique sensitivity to stress-relief time, ihis is supported by the data in Figure 12-2 which show the Charpy 50 ft-lb data from the results of Charpy evaluations performed to determine the effects of stress relief times. *

A statistical analysis was performed on the two data sets and selected subsets to determine the mean and standard deviation. These data are summarized in Table 14-4. A review of the data illustrates the influence of the weld metal 72105 data on both the mean initial value and in some instances standard deviation. The influence of all the data for welds made with weld wire 72105 is pronounced on both the mean value and in some instances the standard deviation. The mean value increases from -4.8F to

+7.0F ar.d the standard deviation nearly doubled from 19.7F to 32.2F.

However, by eliminating all the data for stress-relief times of 40 hours4.62963e-4 days 0.0111 hours 6.613757e-5 weeks 1.522e-5 months or greater, the influence of the data on the overall metn and standard deviation are negligible. This latter position is acceptable because none of the reactor vessels containing weld metal WF-70 have stress-relief times greater than 35 hours4.050926e-4 days 0.00972 hours 5.787037e-5 weeks 1.33175e-5 months . However, to include all the weld metal 72105 data would unjustly penalize the other kald metal initial RTNDT temperatures especially as related to the increase in standard deviation, It is apparent from the above that there are two dt; tinct data populations with regard to Mn-Ho-Ni/Linde 80 weld metals. The first is the total Mn-Mo-N1/Linde 80 less weld metal 72105 data, and the second is the 72105 weld metal. Based on this observation, it appears practical to identify an initial mean RTNDT value and standard deviation specifically for weld metal WF-70 based on the data obtained for weld wires fabricated with weld wire 72105.

The mean and standard deviation data base for the HF-70 and HF-209-1 weld metals are included in Table 14-4. The various subsets were analyzed as based on the rationale described above for the selection of the data at stress-relief times of less than 40 hours4.62963e-4 days 0.0111 hours 6.613757e-5 weeks 1.522e-5 months . Based on this criterion, the analyses of the data produced a mean initial RTNDT value of +17.4F and a corresponding standard deviatio=. of 20.0F, Actually, the data from the Oconee Unit 3 sursaillance program is inconsistent with similar data. If the Oconee 3 data is deleted, the mean value would become +11.0F with a standard deviation of il.5F. A background evaluation of the Oconee Unit 3 data did not provide any justifiable reason for deletion of the data. Therefore, tha former set of values (i.e. which includes the '<onee 3 date) will be usen rather than the latter for licensing applications where initial RTNDT and standard deviation values are neeJed.

The relationship of the WM 72105 data stress-relieved for less than 40 hours4.62963e-4 days 0.0111 hours 6.613757e-5 weeks 1.522e-5 months is shown in Figure 14-3 and is compared to the mean standard deviation for the Mn-Mo-N)/Linde 80 data less HM 72105 data. If the Oconee Unit 3 data is deleted, the remainder of the less than 40 hour4.62963e-4 days 0.0111 hours 6.613757e-5 weeks 1.522e-5 months stress-relief data falls within the 2 standard deviation limits of the original Hn-Mo-Ni/Linde 80 data. If the WM 72105 data base is expanded to include the 40 hours4.62963e-4 days 0.0111 hours 6.613757e-5 weeks 1.522e-5 months stress-relief point, the mean value increases to 19 '5 xi the standard deviation remains relatively constant. Therefore, u s ; only the less than 40 hour4.62963e-4 days 0.0111 hours 6.613757e-5 weeks 1.522e-5 months stress-relief data does not cause any real bias in the selection of the chosen mean and standard deviation for the initial values for WF-70.

Re c ommen d e d _ Re g u l a tory _Eo sit.lon s InttlaLRIgI_hlue - The initial RTNOT value to be uset for weld metal WF-70 in those cases where no meaiured RTNDT exists is as follows:

Initial RTNDT - 18F Standard Deviation - 20F These values are based on all the data available from weld metals fabricated with weld wire 72105 and which received stress-relief of less than forty hours."

Etquest #2: Provide the basis'for concluding that the. increase in reference temperature for Zion weld metal may be determined from surveillance data irradiated in Babcock and Hilcox designed reactor vessels.

Resoonse #2: When all the available'trradiated RTNDT and' shift data for weld wire 72105 are presented (Figures 14-5 & 14-6), including irradiations from H and B&W vessels, alt data correlates well with Reg. Guide 1.99 Rev. 2 predictions. The available data therefore confirms that the integrated surveillance program approach is valid for B as well as B&W plants containing 72105 weld metal. The cross-referencing of tne surveillance data is allowed through the concept of an integrated surveillance program as described in 10CFR50, Appendix H, Section II.C. The B&W Owners Group's integrated surveillance program which encompasses both B&W and Hestinghouse-designed reactor vessels is fully described in the NRC accepted report BAH-1543, Revision 3. The procedures used to develop the trend and grouping of transition temperature shift data for weld metal HF-70 from both B&W and Westinghouse-designed vessel surveillance programs are those described in Regulatory Guide 1.99, Revision 2, Position 2. The rationale for this approach is discussed in detail in BAH-2100, page 14-4 and the appropriate paragraphs are extracted and presented here as follows:

" Evaluation of Shift of RT g Qata Base - The surveillance data available for weld metals fabricated from-72105 constitute one of the largest sets of data for an individual weld metal-that exists in any data base. These fourteen individual data sets (fourteen separate irradiations) are presented in Section 11, Table 11-1, and repeated here in Table 14-5 for continuity, and are all the data available up to the time of this report. All these data have been verified by a thorough review of all source documents and the fluence values are based on current re-evaluations of the capsule fluences.

Irradiated Data Behavior - The data were evaluated on the basis of the 30f t-lb temperature shif t and the n adiated 30 f t-Ib temperature. These-data are plotted as a function of fluence and are presented in Figures 14-4 and 14-5. For comparison, the Regulatory Guide 1.99, Revision 2 curves based on 0.35% copper and 0.59% nickel (CF=211) are included-in Figure 14-4 with the 30 ft-lb temperature shift data. This comparison demonstrates the extreme conservatism of the Regulatory Guide methodology when compared to the actual 30 ft-lb temperature shift data. The irradiated data is compared (11)

ZNLD/2479/4

to the prediction curves based on the Regulatory Guide (CF-184) and the initial mean RTNDT values and standard deviation, in Figure 14-5. -This-comparison also illustrates the conservatism of the Regulatory Guide methodology compared to actual data behavior and demon 3trates a more-realistic representation of the data behavior.-

The irradiated data were analyzed using the procedures described.in Regulatory Guide 1.99, Revision 2. Position 2. The results of this' analysis based on tne 30 ft-lb temperature shift data are shown in Figure 14-6. This-approach resulted in a chemistry factor of 174 as compared to a chemistry factor of 211 based on the typical HF-70 chemical composition of N1 - 0.59%

and Cu - 0.35%. A chemistry factor of 174 implies that the weld metal irradiation sensitivity is the equivalent of a copper content of 0.'25%

assuming Ni - 0.59%. The procedure from Position 2 was applied to a data group consisting of the fourteen irradiated 30 ft-lb temperature data-. sets in ,

contrast to the shift data for normal Position 2 analysis. The~1rradiated Charpy 30 ft-lb temperature data in Figure 14-5 were analyzed using the methodology described in Regulatory Guide 1.99, Revision 2, Position 2. A chemistry factor of 184 was calculated (see Figure 14-5). Using the relationship that initial RTNDT plus irradiated shift equals the irradiated value, it follows in this case that the differences of_the two chemistry factors is 10. If this is adjusted by multiplying by the fluence-factor, an RTNDT value approximately equivalent to the difference between 174 and 184 is.

obtained for the fluence of interest and is representative of the initial.

RTNDT value. This relationship supports the selection of a value of IlF for the generic initial RTNDT value by indicating a 10F differential between the two values.

titthodology for Calculatina Shif t in RTg - The shift in RTNDT resulting from irradiation shall be in accordance with Regulatory Guide 1.99, Revision 2, Position 2. Based on the available fourteen irradiated-data sets, the-chemistry factor for WF-70 weld metal is 174. The margin shall.be calculated based on one standard deviation = 14F t i .e, '1/2 of Posliion 1 o3 - 28F)."

Requelt_#3: Plant Specific irradiation temperatures and spectra should be included in your evaluation of the effect of neutron irradiation on the increase in reference temperature.

Respone_ #J: Plant specific irradiation-temperatures are discussed in detall_in BAW-2166 which is the B&W Owners Group response to Generic Letter 92-01.__The applicable reactor coolant system temperatures as a function of power are reproduced here for the applicable reactor vessels.

" Material sensitivity to irradiation embrittlement is directly affected by irradiation temperature. Over the temperature range that most light-water cooled reactors operate, the irradiation embrittlement is inversely related to irradiation temperature. However, since current generation' pressurized water cooled reactors operate over a the relatively narrow temperature range (i.e. 529-556F RV inlet temperature), the relative sensitivity of the belt line materials as a function of temperature is easily overshadowed by other parameters such as variations in material properties and Charpy impact testing techniques. The development of Regulatory Guide 1.99, Revision 2, was based solely on surveillance data in the irradiation temperature range of-525 to 575F. Normally, the Regulatory Guide 1.99, Rev. 2 data is applied directly in the evaluation of a reactor vessel on the assumption that the reactor vessel temperature was always within this temperature range.

However, as can be seen from a review of reactor coolant system temperature as a function of power, the inlet temperature can vary. This does not affect-the monitoring of irradiation embrittlement of the reactor vessel because.the surveillance capsules are located in the downcomer region of the reactor vessel and experience the same temperature history as the reactor vessel.

The reactor coolant system temperatures as a function of power for each plant included in this report are reviewed below. These data were provided by each plant owner and are as stated in their respective FSAR's.

"4. L B&W-Designed 177-E M lants Figure 4-1 shows the reactor vessel outlet temperature (THot) and the reactor vessel inlet temperature (TCold) for the B&W 177-FA reactor vessels.

4 This is representative of all 177-FA plants except-Davis-Besse. !;Iese operating. limits are characterized by a constant system average-tempe.rature and an increase to the inlet temperature-(TCold);to 580F with a reduction in operating power. These temperature characteristics result from the fact that initial approach to power is controlled by the water level-in the steam t generator followed by a change in. operation to maintain the system average temperature constant. The increaso in inlet temperature may have the.effect of minimizing irradiation embrittlement for these plants.

1.2. Davis-Stist Figure 4-2 shows the reactor vessel outlet temperature (THot) and th'e reactor vessel inlet temperature-(TCold) for the Davis-Besse reactor vessel. The system behavior is similar to that of the other 177-FA plants with the' exception that the change from level control of system average temperature--is at approximately 287. power.

4.7. Zlon Units _] and 2 Figure 4-7 shows the reactor vessel outlet temperature (THot) and the reactor vessel inlet temperature (TCold) as a function of power for the Zion Units 1 and 2 reactor vessels. These operating limits are characterized by an increasing average temperature with increasing power levels. The . inlet temperature decreases with increasing power and reaches a minimum at 1001.

power."

~

The differences in the operating-temperatures of-the B&H NSS. designs and the Westinghouse NSS design for the Zion units shows an inlet temperature difference of approximately 26F; however, this temperature spread is within the allowable temperature range for the applicability of Regulatory Guide 1.99,-Rev. 2.

Therefore, it is not necessary to apply or to take special considerations of these temperature differences.

Likewise, the issue of the effects of neutron spectra was considered in the design of the Master Integrated Reactor Vessel Surveillance Program as_ described in BAW-1543, Revision 3 (approved _by NRC) and_ls extracted as follows:

"Itte._r_ththe neutron _ energy _snentrum is a function of- the' geometry and materials-of the reactor internals components. As shown in' Tables 3-2 and 3-6, the materials of the reactors are-the seme, but the dimensions of the internals vary and will produce some variation in neutron spectra.

Differences in neutron spectra, however, are not unique'to integrated programs. A surveillance program for a single reactor must contend with the variation in spectrum through the reactor vessel wall and the difference in spectrum between the vessel and the survel!1ance capsule. In the integrated program, the difference in spectra between the hestinghouse and B&W reactors is no larger than that already encountered in non-integrated programs. ,The difference in spectra could be ignored if a perfect damage exposure index-existed. Since this is not the case, it is desirable to hold the difference in spectra to a minimum and correlate damage in a specimen _with different points in the reactor vessel wall using the best available damage function.

The effect of spectra variations will continue'to be evaluated in the integrated program just at it would also continue to be evaluated in a non-integrated program.

As an example of the evaluation to be considered, the neutron energy spectrum at the reactor vessel for a typical Westinghouse system design is compared with a typical B&W system design and is shown in Figure 4-1."

Re_ quest #3: Provide the Charpy impact data and curves that were used to determine the increase in the 30 ft-lb transition temperature.

Response #4: The charpy impact data and curves are found in BAH-1803, Revision 1 and in surveillance capsule reports. These data and_their-interpretation are.

included in BAH-2100 for weld _ metal HF-70. All Charpy data were reevaluated to provide a consistent approach on the determination of transition temperatures and upper shelf energies. The appropriate paragraphs as extracted from BAH-1803, Rev.

I are presented as follows:

"4.4. QAtA_lD_teIDIe_titi.OD 4.4.1. Charoy A tc_t Curves The Charpy impact data were obtained from capsule evaluation reports issued from 1969 to 1986. Since these evaluations were performed at different test facilities, the data received different-interpretations which were influenced by the experience of the evaluator; to minimize _the effect of this, all the Charpy data were re-evaluated. The Charpy data and re-evaluated curves are included in Appendix A. Some of the reported' transition temperatures and Cy VSE values were found to be inconsistent with the reported Charpy data; other values were found to be different because of the interpretation of the data.

In those few cases where the data-were insufficient to define the complete upper-shelf region, our experience with these materials was-drawn upon to extend the data in a rational manner; these extended curves were drawn with a broken line.

4.4.2 Transition Tegnertt.urg To determine the effect of neutron radiation on the reference temperature, the shift in the Charpy energy curve tempeiature at 30 ft-lbs is measured, in agreement with the current requirements of 10CFR50, Appendix G. This is a change from the original requirement of making the measurement at 50 ft-lbs.

(25)

ZNLD/2479/9

- .- . . . . ._= .._ - . .

Whenever the. upper-shelf energy decreased to below the 50 f.t-lbs value, itI was impossible to measure a shift. The new. requirement also states that the-shift measurements is to be based on the' average Charpy curve of the:

irradiated material relative to that of the unirradiated material.

The charpy shift data for the various Linde 80 weld metals include all the data from the B&H-designed reactor survelliance programs and all-the-data from the various pressurized water reactor surveillance programs that were established for reactor vessels fabricated by B&W.

The Charpy shift data for each weld metal arc prGsented in Tables 4-2 and 4-3. The Charpy 30 ft-lb shift data for the B&W-designed NSS reactor v!stel surveillance programs are plotted as a function of fluence'in Figure 4-1.

The value: beside each plotted point is the copper content. Similar data is shown in Figure 4-2 for non-B&W NSS reactor vessel surveillance programs.

These data are also plotted as a function of fluence along with their corresponding copper contents.

4.4J Upper-Shelf _ Energy The effect of neutron radiation on the fracture toughness of the weld metals, in the region where the material behavior is defined as plastic,:is measured by the decrease in C USE.y The fundamental difficulty with the measurement of this characteristic of the Charpy data is the lack of a standard definition of what constitutes the " upper-shelf",I The main reason for this is that Charpy curves exhibit varying characteristics (shapes) in the region of interest. This can be seen by examining the curves in Appendix A.

For the purpose of this study, all C VSEs y were defined by a_ combination of (1) an appreciation of the general characteristics of the behavior of the curves for a given weld metal, (2) comparison of the upper-shelf values in the temperature range of 150 to 200F above the temperature where 1001. ductile failure was observed, and (3) particular ovpertise gain M by working with and evaluation of these weld metals. In nest cases, the values selected could be argued to be slightly above or below those chosen; however, this method provided consistency to the data Interpretation.

ZNLD/2479/10

r The decrease in Cy USE values is summarized in Tables 4-2 and 4-3'. These tables include all the data from.the various pressurized-water reactor-surveillance programs for B&N-fabricated reactor vessels. These data have-the same chemical composition as the' shift dhta. The irradiated Charpy USE.

data for the B&Hadesigned NSS reactor vessel surveillance programs are-1 plotted as a. function of fluenco in Figure 4-3 and the corresponding non-B&W?

NSS data _is presented in Figure 4-4. The copper contents of the data is

~

presented beside each data point."

I At the' time this work was in progress the ASTM-Committee Elo.02 had not completed formalizing-a definition of upper-shelf energy. The_ process used in this report closely approximates the procedure recommended by ASTM.

-Renue11_t5:. Identify the neutron transport code, the-scattering. cross-sections-and quadrature 1 approximations used in determining the neutron fluences of the capsules.

Responie_f5: Neutron' fluence-analysis information, including-the neutron transport ,

codes, scattering cross-sections and quadrature-approximations are found in the references identified in BAW-1803, Rev. 2, Tables 4-4 and 4-5 (see following ;

page). These data and their interpretation are included in BAW-2100 for-tLe weld metal HF-70. The appropriate paragraphs as extracted from BAW-1803, Rev. 1, are ,

presented as follows:

"1,1._ _Jeler tlen.sLElv e n c e_Valv e.s Fluence values for surveillance capsules are continually upgraded as t.etter-techniques are established for determining reector flux and fluences.

Surveillance capsule fluence values have been reviewed in detail as a part of a Nuclear Regulatory Commission (NRC) sponsored dosimetry improvement programs. As a result of these reviews, revisions to the older fluence values have occurred.

The fluence values for this study were based on two considerations. For B&W plants, fluence values were used as reported since these procedures were benchmarked as a part of a NRC sponsored program at Hanford Engineering Development Laboratory (HEDL); for some of the older-(non-B&W) plants, capsule fluence values were updated, when available*, to agree with the values calculated by HEDL. More-recent Westinghouse fluence values were used without change since their procedures were benchmarked against HEDL as part-of their dosimetry pcogram. In the case of the latest available capsule data, the capsule fluence values were obtained from published capsule reports. A listing of-the sources of the fluence data are presented in Tables 4-4 and 4-5."
