UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001
~rch 22, 1996 Dr. Robert C. Mecredy Vice President, Nuclear Operations Rochester Gas 8 Electric Corporation 89 East Avenue Rochester, NY 14649
SUBJECT:
R.E.
GINNA NUCLEAR POMER PLANT PRESSURIZED THERMAL SHOCK EVALUATION (TAC NO. M93827)
Dear Dr. Mecredy:
By letter dated October 11,
- 1995, you submitted an updated pressurized thermal shock (PTS) evaluation for the R.E. Ginna Nuclear Power Plant (Ginna).
The NRC staff has completed its review of your submittal.
In the enclosed safety evaluation (SE), the staff concludes that the Ginna reactor vessel is projected to be below the PTS screening criteria at the expiration of its license.
Since this conclusion is dependent upon the available chemistry and surveillance data, it is subject to change when new data become available.
Additionally, the Ginna reactor coolant system pressure and temperature limits report, as referenced in Ginna Technical Specification 5.6.6, should be updated to include the material properties discussed in the enclosed SE.
The update should cover the use of the ratioing procedure in Regulatory Guide 1.99, Revision 2.
Also with regard to your specific methodology for determining low-temperature overpressure protection setpoints and its application of American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code)
Case N-514, you should request an exemption from 10 CFR 50.55a to use the ASME Code Addenda that incorporates Code Case N-514,Section XI, Division 1, "Low Temperature Overpressure Protection,"
approved February 12, 1992.
Sincerely, Docket No. 50-244
