Subject:

Beaver Valley Power Station, Unit No. 2 Docket No. 50-412, License No. NPF-73 Proposed Operating License Change Request No. 62 (TAC No. M82370)

Enclosed are the following:

1. An application for amendment to the above license to revise Table 3.2-3 of Technical Specification 3.2.5 which ensures DNB related paramuters are maintained within limits. The specific revision to Table 3.2-1 would be to lower the reactor coolant system flow uncertainty value from 3.5% to 2.0%, and to lower the measured reactcr coolant system flow limit from 2 274,800 gpm to 270,850 gpm.
2. Documents designated Attachment A, B and C which set forth, respectively,- the chenge in the technical specifications, the safety analysis (including the no significant hazards evaluation), and the typed replacement technical specification page.

This change has been reviewed by the Onsite Safety Committee and Offsite Review Committee and was determined to be safe based on the attached safety analysis.

Unit No. 2 will be entering its third refueling outage in March of .1992. We anticipate increased steam generator tube plugging following the examinations scheduled for this outage. Approval of this proposed change will provide additional reactor coolant system flow margin which may be needed following plugging activities. We

' request NRC approval by April 15, 1992, in order to support plant restart following this outage.

Sincerely,

/ , {9!
