"Analysis of Capsule "S"
from the Rochester Gas and Electric Corporation R.
E.
Ginna Reactor Vessel WCAP 13902 December 1993", dated March 29, 1994
Dear Mr. Johnson:
The reference (a) letter requested information to support closeout of issues addressed in Generic Letter 92-01.
Specifically, it was requested that data listed in two tables attached in that reference be evaluated and updated
.as required.
Rochester Gas and Electric Corporation (RG&E) provided its initial response in reference (b).
It is the intent'of this letter to complete RG&E's response.
The data applicable to the R.
E. Ginna reactor vessel are provided in Tables 1 and 2 attached.,
These data reflect results derived from the latest surveillance capsule (ref.
c) and information derived through the B&W Owners Group.
The attached data supersedes the data provided in reference (b).
t; The B&W Owners 'Group has, provided Topical Reports BAW-2178PA and BAW-2192PA which present equivalent margin analyses to address conditions of low upper-shelf energy.
Though the R.
E.
Ginna reactor vessel does not, demonstrate low upper shelf energy for its limiting SA-847'eld
- material, RG&E endorses the results and conclusions ggesented in these reports and may choose to apply 9407120310 940M'0 PDR ADOCK 05000244 P
PDR pgrP4 ZD//K/A~~T ggS ',

these reports to the Ginna reactor vessel should conditions later warrant.

Subject:
Reactor Vessel Structural Integrity, 10CFR50.54(f),
Response to Generic Letter 92-01, Revision 1, R. E. Ginna Nuclear Power Plant.
2.
Values determined from WCAP-13902 and WCAP-13893.
3.
Values determined from data in Material Test Report.
4.
Value determined from data in EPRI NP-373.
5.
Mean value from data in BAW-1803, Revision 1.
6.
Chemistry Factors for forging 125S255VA1 and forging 125P666VA1 were determined using REG surveillance data as reported in WCAP-13902 and WCAP 13893.
7.
Chemistry Factor for weld metal SA-1101 was determined using TP3 surveillance data for weld metal SA-1101.
The TP3 30 ft-lb transition temperature shift data were obtained from BAW-1803, Revision 1, while the fluence data for the capsules were obtained from BAW-1803, Revision 1 and NUREG CR-3319, Revision 1.
8.
Chemistry Factor for weld metal SA-847 and weld metal SA-848 was determined using BGWOG surveillance data for weld metal SA-1135 and REG surveillance data for weld metal SA-1036.
These surveillance welds were fabricated with the same wire heat as weld metal SA-847 and weld metal SA-848.
The BGWOG surveillance data were obtained from BAW-1803, Revision 1.
The REG surveillance data were obtained from WCAP-13902.
9.
No data available for this material, therefore, 0.35% is specified as defined in Regulatory Guide 1.99, Revision 2 ~

Values obtained from BAW-2121P.
12.
Values obtained from BAW-1500.
