Technical Specification Improvement Program Rochester Gas & Electric Corporation R.E. Ginna Nuclear Power Plant Docket No. 50-244

Dear Mr. Johnson,

Rochester Gas and Electric (RG&E) currently anticipates submitting the proposed conversion to Improved Technical Specifications (ITS) consistent with NUREG-1431 later this month. Included within this submittal are several changes to the existing technical specifications (TS) that are supported by engineering calculations or other documents that will require NRC Staff review and approval separate from the conversion review. Based on recent conversations, the NRC has requested that RG&E provide these documents prior to the ITS submittal to allow the NRC Staff additional time for review. Therefore, attached are the following documents:

(a) "Criticality Analysis of the R.E. Ginna Nuclear Power Plant Fresh and Spent Fuel Racks, and Consolidated Rod Storage Canisters," dated June 1994.

(b) WCAP-14040, "Methodology Used to Develop Cold Overpressure Mitigating System Setpoints and RCS Heatup and Cooldown Limit Curves," Revision 1, December 1994.

(c) RG&E Methodology for Determining the Low Temperature Overpressure Protection System (LTOPS) Setpoints.

The spent fuel pool criticality study is required to support an increase in allowed fuel enrichment necessary to support a conversion ,to 18 month fuel cycles which is planned to begin following the 1996 refueling outage. An increased in fuel enrichment affects current Ginna Station TS 5.3.1.b and TS 5.4.

~ GgQQ oi 95OS<S00<4 9S0505 PDR ADGCK 05000244 P PDR,';

The remaining two documents support the incorporation of a Pressure Temperature Limits Report (PTLR) which is planned to be implemented during the conversion to ITS. Since Ginna Station utilizes the LTOPS for preventing overpressurization of the residual heat removal system, Section 3.0 of WCAP-14040 does not apply to the installed system. Therefore, RG&E specific methodology is provided for your review. Both the RG&E specific methodology and a red-line markup of the methodology provided in WCAP-14040 are provided.

All items proposed to be relocated from the current Ginna Station TS to the PTLR are addressed by these two documents.

The items RG&E anticipates to be relocated to the Core Operating Limits Report (COLR) are provided in attached Table 1. As can be seen from this table, NRC approved methodology exists for all items proposed to be relocated such that no documents require submittal to the NRC at this time.

The current schedule for implementation of the ITS for Ginna Station indicates NRC Staff approval of the proposed new TS by November 1995. Therefore, RG&E requests that NRC review of these three documents be coordinated to support this schedule.
