Changes to Technical Specification Instrumentation Requirements Conversion to Improved Technical Specifications Rochester Gas 2 Electric Corporation R.E. Ginna Nuclear Power Plant Docket No. 50-244

Dear Mr. Johnson,

By Reference (a), RGB'roposed to convert the current Ginna Station Technical Specifications to the Improved Standard Technical Specifications (i.e., NUEEG-1431). Included within this conversion were numerous changes to the current requirements for the Reactor Trip System (RTS) and Engineered Safety Features Actuation System (ESFAS). Several of these changes were based if on Reference (b), which approved, would allow up to 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> to place inoperable RTS and ESFAS channels in the tripped condition and allow the bypass of an inoperable channel for up to 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. Based on conversations with NRC staff RGEcE has agreed to defer these changes until after the conversion process since WCAP-14333 has not yet received staff review and approval. In place of the changes justified by WCAP-14333, RG&E proposes to implement those documented in References (c), (d), and (e) which have received NRC staff review and generic approval.

The purpose of this submittal is to provide the necessary justification to implement the changes to the RTS and ESFAS surveillance requirements and required actions as documented in WCAP-10271 and its supplements. In order to support NRC review of this change, this submittal is organized as follows:

The implementation of WCAP-10271 and other related changes is documented in this.

submittal as a separate license amendment request (LAR) with respect to the current Ginna Station Technical Specifications. Therefore, the required plant specific justification of this implementation and significant hazards consideration are provided in this submittal.

b. The implementation of WCAP-10271 and other related changes and the removal of WCAP-14333 with respect to Reference (a) is being provided for the marked up Ginna Station Technical Specifications only (i.e., Attachment A and B to Reference (a) has been revised to show the resulting differences). The necessary changes to the NUREG-1431 markups (Attachment D to Reference (a)) and the proposed Improved Technical Specifications for Ginna Station (Attachment C to Reference (a)) willbe provided at a later date.

Based on the above, the review of this submittal should be coordinated with the overall NRC review of the May 26, 1995 submittal since they are interrelated.
