Subject:
Application for Amendment to Facility Operating License, Revision to Reactor Coolant System (RCS) Pressure and Temperature Limits Report (PTLR)
Rochester Gas Ec Electric Corporation R E. Ginna Nuclear Power Plant Docket No. 50-244
Dear Mr. Vissing,
By Reference (a), the NRC approved changes to Administrative Controls Section 5.6.6 ofthe Ginna Station Technical Specifications which allowed referencing of Revision 1 of the Ginna Station PTLR for the RCS pressure and temperature (P/T) limits and low temperature overpressure protection (LTOP) limits. However, this approval was only provided until December 31, 1996 since the fluence factors used to generate the values provided in PTLR Revision 1 were estimated and not based on the methodology required by Reference (b). As such, the NRC required that RGAE submit a license amendment request (LAR)with a new PTLR by October 2, 1996 using the methodology provided in Reference (b) to allow the NRC time for appropriate review.
Therefore, the purpose of this letter is to provide the required LAR, Revision 2 to the PTLR, and the necessary supporting calculations (i.e., WCAP-14684).
Since the P/T limits provided in Revision 2 of the PTLR were developed using the methodology of Reference (b), the LARwill incorporate reference to this methodology into the Administrative Controls section.
The LTOP limits are based on the methodology ofReference (c) which is already listed in the Administrative Controls section.
As such, these changes will allow RGB to perform future P/T and LTOP evaluations using NRC approved methodology without requiring a potential technical specification change.
The change willalso complete incorporation of Generic Letter 96-03 into the Ginna Station Technical Specifications since the existing Ginna Station PTLR cannot be revised without a license amendment request (LAR).

)LiDI Consistent with Generic Letter 96-03, the proposed revised PTLR contains:
(1) reactor vessel material information, (2) LTOP setpoints, and (3) P/T curves. Although the NRC recently approved a new pressurized thermal shock (PTS) evaluation for Ginna Station (Ref. (d)), the use ofthe new fluence values (and additional surveillance capsule chemistry samples) impacts that evaluation as documented in WCAP-14684. In summary, this letter provides the following:
An LARwhich revises Administrative Controls Section 5.6.6 to replace the reference to the May 23, 1996 NRC letter (which is the basis for the existing LTOP and P/T limits) with a new reference containing the NRC's approval ofthe attached PTLR. In addition, the list of documents containing the approved NRC methodology willbe updated to reference WCAP-14040-NP-A for the P/T curves and this letter. The methodology for the LTOP setpoints and enable temperature (Ref. c) remains unchanged.
Finally, a typographical error is corrected.
b.
Revision 2 ofthe PTLR which contains the following:
Update of all reactor vessel material information as documented in WCAP-14684.
ii.
Revision to the LTOP enable temperature using the methodology submitted as Attachment IIto Reference (c) due to the revised P/T curves.
The LTOP setpoints remain unchanged as based on the calculation included as Attachment IV to Reference (e).
iii.
Update ofthe P/T curves based on the methodology ofReference (b) as documented in WCAP-14684.
c.
WCAP-14684 which provides supporting calculations.
Since the existing PTLR expires on December 31, 1996, RGkE requests NRC consideration ofthis LARby December 15, 1996 in order to support necessary implementation.
Very truly yours, Robert C. Mecredy MDF$870 Attachments
