Docket Nos. 50-348 and 50-364 Mr. W. G. Hairston, III Senior Vice President Alabama Power Company i
40 Inverness Center Parkway Post Office Box 1295 Birmingham, Alabama 35201
Dear Mr. Hairston:
I
SUBJECT:
RESPONSE TO GENERIC LETTER 88-11. "NRC POSITION ON RADIATION EMBRITTLEMENT OF REACTOR VESSEL MATERIALS AND ITS IMPACT ON PLANT OPERATIONS," FOR JOSEPH M. FARLEY NUCLEAR PLANT, UNITS 1AND2(TACNOS.71491AND71492)
Generic Letter 88-11 requested that licensees submit the results of their technical analyses, performed using the methodology contained in Revision 2 to Regulatory Guide 1.99, that predict the effects of neutron irradiation on reactor vessel materials.
By letter dated November 23, 1988, as supplemented by letter dated September 17, 1990, you responded to Generic Letter 88-11 and provided the requested information. Your response stated that the technical analysis for Joseph M. Farley Nuclear Plant -(Farley), Unit 1, showed that the current heatup and cooldown limits in the Technical Specifications are bounded l
by the new methodology of Revision 2 to Regulatory Guide 1.99. For Farley, L
linit 2, the analyses indicated that new Technical Specification heatup and
- ooldown limits would be required.
We have reviewed your response.to Generic Letter 88-11 and have performed a confirmatory analysis for farley, Unit 1.
As discussed in the enclosed Safety Evaluation, we concur that the current heatup and cooldown limits in the Farley, Unit 1. Technical Specifications are valid through 16 effective full l
power years of operation on which the current limits are based.
However,.
I compliance with the requirements of 10 CFR Part 50, Appendix G, for a minimum upper shelf energy of 50 ft-lb at end-of-life for the limiting reactor vessel material could not be verified. Operation through 16 effective full power years of operation is acceptable, but future submittals will need to demonstrate that this requirement continues to be met.
For Farley, Unit 2, you stated that as a result of your analyses, revised heatup and cooldown limits in the Technical Specifications were required.
By letter dated August 27, 1990, you requested an amendment to the Farley, Unit 2 y
Technical Specifications to revise the heatup and cooldown limits.
In your subrittal, you stated that the revised limits were calculated using the t
methodology contained in Regulatory Guide 1.99, Revision 2.
This amendment request is currently undsr review by the NRC staff, t
