IE BULLETIN 80-20 SHOREHAM NUCLEAR PCWER STATICN - UNIT 1 DOCKET NO. 50-322

Dear Mr. Grier:

IE Bulletin 80-20 describes the malfunctioning of Westinghouse Type W-2 three position, spring return to neutral position, control switches. Contact closure was intermittent with these switches in the neutral (or spring returned) position.

As directed by the Bulletin, a review has been conducted of all safety-related systems to determine if this type of Westinghouse switch has been used. No Westinghouse Type W-2, spring return to neutral position, control switches have been used in safety-related applications at Shoreham.

In response to your request for information to assist in evaluating the value/ impact of each Bulletin, we estimate that approximately 8 engineering manhours have been expended in responding to this Bulletin.

We trust that the above information has been responsive to your request. Should you require additional information, please do not hesitate to centact us.

Very ruly yours, 0
