Conversion to Improved Technical Specifications, 24 Month Refueling Cycles Rochester Gas &Electric Corporation R.E. Ginna Nuclear Power Plant Docket No. 50-244
Reference:
(a)
Letter from R.C. Mecredy, RG&E, to A.R. Johnson, NRC,
Subject:
Conversion To Improved Technical Specifications, dated May 26, 1995.
Dear Mr. Johnson,
By Reference (a), RG&E proposed to change the definition ofrefueling interval from 18 months to 24 months as part of the conversion to improved technical specifications for Ginna Station.
Attachment H of Reference (a) contains discussion related to the impact of the refueling interval change on instrumentation and mechanical equipment at Ginna Station.
Section D.3 and Table 4 of this attachment evaluate the change with respect to the reactor trip system, ESFAS, and other miscellaneous components.
Section D.3 makes a statement that "Ginna Station has not observed failures ofthese functions during previous testing." This statement was based on a review ofplant records associated with the tests listed on Table 4 between January 1985 and January 1995. This review, and a similar review of NPRDS records, did not indicate any failures of the subject components during this time frame.
As such, RG&E believes that historical data supports a
increased testing frequency of 24 months.
Please contact Mark Flaherty at (716) 724-8512 ifyou have any further questions.
Very t y yours, Robert C. Mecredy t '"-(.'073
