Turbine Driven Auxiliary Feedwater Pump Operability Requirements R. E. Ginna Nuclear Power Plant Docket No. 50-244

Dear Mr. Russell:

This letter responds to a request, from your Staff that we document the additional requirements that we have placed on the operability of the Turbine Driven Auxiliary Feedwater Pump (TDAFP). Ginna Procedure A-52.4 has been revised to state: "In accordance with Technical Specification 3.4.1(c) and 3 '.2(b'~,

the following is provided as additional administrative requirements to clarify operability. In order for the TDAFWP to be considered operable, at least 1/2 feedwater flowpaths to either Steam Generator and 1/2 steam supply paths from either steam generator must be operable (including valves and piping). If the TDAFWP or both feedwater flowpaths or both steam supply paths are inoperable, restore within 7 days or be in HSD within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and at an RCS Temperature < 350 F within the following 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />".

In addition, the operators have been provided with the additional guidance that, for compliance with Technical Specifi-cation 3.4.2(c), both TDAFP steam supply systems and both TDAFP feedwater flowpaths must be operable.

We are preparing a proposed Technical Specification change to incorporate additional requirements for the TDAFP system. It should be noted that -the, proposed changes may differ from our current interim requirements.

Very truly yours, R. C. M ed General Manager Nuclear Production xc: Ginna Senior Resident Inspector i)p FDC 85'0 PDR l80193 85"0207 ADGCK 0 080244 t ~
