Proposed Staff Actions to Improve and Maintain Diesel Generator Reliability

Subject:

Request for Extension to Submit Response to Generic Letter 84-15 j.

Dear Sir:

Boston Edison Company (BECo) has reviewed the referenced Generic Letter 84-15, dated July 2, 1984. This letter requires BECo to submit information to the NRC on or before October 1,1984, regarding diesel generator (DG) surveillance tests, reliability data and reliability programs, or request an extension by August.16,1984.

BEco has developed a plan and schedule related to diesel generator reliability to address these issues. Based on this plan, BECo l

herein requests an extension to January 31, 1985, to submit a response. Our justification for the requested extension is as follows:

a)

At present, BECo is engaged in RF0#6 which involves modifications related to recirculation pipe. BEco has committed all available c-resources to conduct and manage outage related activities, thus the BEco Staf f would not be available until after the start up of PNPS.

BECo intends to complete the planned and on going outage related activities on schedule.

b)

A preliminr.ry review of the DG Surveillance Testing frequencies related to cold fast start ups and ECCS, indicates that a reliability analysis t#ould be required to propose any changes-in technical specifications (TS).- This reliability analysis would be the basis for a no significant hazards consideration determination for proposed T.S. changes.

Further, to fully evaluate and~to address the guidance of NUREG/CR-0660 and the Staff proposed reliability program, it is estimated that at-least 120 days would be required following the

-start up of PNPS.

v EDLTON EDCON COMPANY MP, Darrell G. Eisenhut Page 2 We believe our request for extension is justified for the aforementioned reasons, and because sufficient time to evaluate diesel generator reliability is essential in formulating any meaningful changes in the technical specifications.

Should you require further information concerning this request, please contact us.

Very truly yours, WGL/ns comonwealth of Massachusetts)
