Beaver Valley Power Station, Unit No. I and No. 2 BV-1 Docket No. 50-334, License No. DPR-66 BV-2 Docket No. 50-412, License No. NPF-73 Typed Pages for Technical Specification Change Request Nos. 221 and 90 Typed, final technical specification pages for Technical Specification Change Request Nos. 221 and 90 are enclosed as Attachments B-1 and B-2, respectively. Also, summary descriptions of non-intent editorial changes _which have been incorporated into the specifications are provided in Attachments A-1 (Unit No.1) and A-2 (Unit No. 2).
The enclosed technical specification pages have been amended to reflect non-intent editorial changes. The changes denoted in Attachments A-1 and A-2 are the result of a conference call, conducted on October 12,1995, between the NRC and members of my staff, concerning the change request noted above. This submittal represents the revised proposed wording to resolve tle NRC reviewer's concern on the original proposed wording submitted on July 20,1991 In addition, minor non-substitutive format changes have been incorporated in this submittal that have no affect on the intent of the technical specification requirements.
If you have any questions regarding the attached information, please contact Mr. G.

Revise footnote (6) to read as follows:
(6) The frequency limits apply for the diesel generator at full accident loading. An engineering evaluation of the test data at lower loads can be performed to demonstrate operability.
i B 3/4 8-3 4.
Add to Bases:
Footnote (6) pennits an engineering evaluation to be performed if the frequency limits of SR 4.8.1.1.2.b.3.b are not met.
The frequency limits prescribed in SR 4.8.1.1.2.b.3.b are based on full load conditions. Since SR 4.8.1.1.2.b.3.b is normally performed at less than full loading conditions, the resultant generator frequency may exceed the required frequency value rar;;c J.m to the design of the diesel generator governor, especially during lower loading. Under lase conditions, it is acceptable to examine the frequency
]
response vs. loading and by an engineering evaluation, determine that the governor is responding properly and would fall within the required frequency band while at full accident loading.
The engineering evaluation consists of l
comparing previous voltage, frequency and power plots with the current plots of these same parameters. By comparing the above data, proper governor response can be verified.
Based on governor response and the current governor droop setting, the frequency value obtained during performance of SR 4.8.1.1.2.b.3.b can be evaluated to ensure the frequency limits of SR 4.8.1.1.2.b.3.b at full accident loading would be met.
