Beaver Valley Power Station, Unit No.1 Docket No. 50-334, License No. DPR-66 Deviations to Generic Letter 83-28 dated July 8,1983 Gentlemen:
The actions required by the above referenced letter are currently being reviewed to identify where improvements are needed.
No schedule can be given at this time for a response to action items 2.2.2 Vendor Interface, 4.2.3 Life Testing of Reactor Trip Breakers, 4.2.4 Periodic Replacement of Reactor Trip Breakers, and 4.3 Automatic Reactor Trip System Actuation.
DLC is a participating member of INP0's Nuclear Utility Task Action Committee (NUTAC) on Generic Letter 83-28, Item 2.2.2.
The NUTAC was fomed for the specific purpose of defining an appropriate vendor inter-face program. Upon completion of NUTAC efforts, and internal review for applicability, a response to Item F...2 will be provided.
The Westinghouse Owner's Group has funded a program to determine the service life of shunt and undervoltage reactor trip attachments. The results of this program will be reviewed and a response to action items 4.2.3 and 4.2.4 will be provided following internal review after the issuance of their report.
In regard to action item 4.3 Reactor Trip System Reliability, 1.'estinghouse has prepared a generic design for incorporation of the shunt trip feature into the automatic reactor protection function. However, plans for implementation of, and deviations from tha generic design will not te forthcoming until the final ATWS ruling is received. This must be done to ensure that the design modifications proposed, address all regulatory concerns of this system.

' Docket N3. 50-334, License No.-DPR-66 Deviations to Generic Letter 83-28 dated July 8,1983 Page 2 Item 3.2.2 requires a check of vendor and engineering recommendations to ensure that the appropriate test guidance is included in the applicatile maintenance procedures. We are reviewing a portion of the safety related pumps, breakers, motors and valve technical nanuals to comply with this part.
We expect that we will demonstrate that our existing and proposed programs are equivalent in the other areas described in the Generic Letter.
