Beaver Valley Power Station, Unit No. 1 Docket No. 50-334, License No. DPR-66 I.E. Bulletin No. 80-19 Gentlemen:

We have reviewed I.Z. Bulletin No. 80-19, " Failure of Mercury-Watted Matrix Relays in Reactor Protective Systems of Operating Nuclear Plants Designed by Combustion Engineering." Based on our review, we conclude that no mercury-wetted relays are installed in the reactor protection system at the Beaver Valley Power Station, Unit No. 1 The letter which transmitted I.E.Bulletin 80-19 requested that we pro-vide an estimate of the manpower expended as a result of this Bulletin. We estimate that 24 man hours have been expended in conducting reviews required by this Bulletin and preparation of the report.

Since no corrective action will be required as a result of this Bulletin, no manpower will be required for corrective actions.

If you have any questions concerning this response, please contact my office.

Very truly yours, iw_= -
