Subject:

Interim 10CFR50.55(e) Report; Westinghouse EMD Cate Valve Position Indication

Dear Sir:

On January 10, 1983, a potentially reportable 10CFR50.55(e) item was reported [ Reference (b)] regarding the potential for certain Westinghouse-manufactured gate valves to indicate they are closed prior to the valve disc fully isolating flow. Should the valve stall or bind following the premature indication, the operator would have an inaccurate indication of true valve position. The reportability of this potential 10CFR50.55(e) item is still under investigation. A detailed description of this deficiency, analysis of safety implications and the corrective action taken will be reported by April 30, 1983.

This letter is being filed pursuant to the interim reporting provision of 10CFR50.55(e)(3).

Very truly yours, YANKEE ATOMIC ELECTRIC COMPANY 8302230449 83021i PDR ADOCK 05000443 ad.
