Dear Mr. Denton:
Serial No. 354B/061478 PO/SWB:svm Docket Nos. 50-280 50-281 License Nos. DPR-32 DPR-37 NRC FIRE PROTECTION SAFETY EVALUATION REPORT SURRY POWER STATION We have reviewed the draft fire protection Safety Evaluation Report.for Surry Units 1 and 2.
As requested by the Commission, Attachment (1) confirms agree-ment to implement previously proposed fire protection modific.ations, additional modifications and technical evaluations documented in Section 3.1 and 3.2 of the Safety Evaluation Report.
All modifications will be implemented by the end of the next Unit 2 refueling following the present steam generator replacement outage.
This refueling is tentatively scheduled to begin March, 1981.
Attachment (2) lists target dates for completion of each modification.
These dates ar~ not commitment dates and represent only estimated completion dates.
These dates may be rearranged if it becomes feasible to shift emphasis to another fire protection modification.
In some cases, the target date represents the date which the work will be sub-stantially complete, but an outage is needed to complete the work.
The modifications proposed and re-evaluation of the adequacy of the fire pro-tection systems should resolve NRC concerns regarding fire protection capa-bility of Surry Power Station. L SWB/svm:3Fl Attachments Very truly yours,
