Response

to Generic Letter 95-07, Pressure Locking and Thermal Binding of Safety-Related Power Operated Gate Valves R.E. Ginna Nuclear Power Plant Docket: No. 50-244 Ref(a):

Letter from A.R. Johnson, NRC, to R.C.

Mecredy, RG&E, "Draft Response to RG&E 60-Day Response to GL 95-07",

dated November 3, 1995 (b):

Letter from E.M. Kelly,

NRC, to R.C.
Mecredy, RG&E, "Ginna Motor-Operated Valve Inspection 95-06", dated June 16, 1995

Dear Mr. Johnson:

RG&E submitted the 60-day response to GL 95-07 by letter dated October 17, 1995.

By reference (a)r NRC stated that RG&E's 60-day response was not fully responsive in that the existence of ongoing WOG efforts does not constitute an acceptable safety basis for deferring the 90-day requested actions of GL 95-07 to 180 days.

As requested by reference (a),

RG&E intends to comply with the 90-day requested actions of GL 95-07 (due November 17, 1995).

A summary of these actions and other information requested by GL 95-07 will be submitted in the 180-day response on February 16,

1996, as requested.

As stated in our 60-day

response, RG&E completed screening and operability assessment on all safety-related gate valves, including all GL 89-10 MOVs, which are potentially susceptible to PLTB.

Our efforts were reviewed and documented by the NRC in reference (b).

RG&E agrees that the WOG proposed program, which we believe it will be beneficial for us to participate in, does not alone assure the safety basis for operability, and our 60-day response was not intended to convey reliance on that program as our approach to assure near term operability for valves susceptible to PLTB.

We believe that based on our screening and operability evaluation efforts, we have already demonstrated that no critical deficiencies exist with regard to our past evaluations, and that initial assessments, using current knowledge, willbe completed by November

'17) 1995.
