SAFETY EVALUATION RY THE OFFICE OF NUCLEAR REACTOR REGULATION PFLATED TO AMENDMENT NO.107 TO FACILITY OPERATING LICENSE NO. DPR-66 DUOVESNE LIGHT COMPANY OHIO EDISON COPDANY PENNSYLVANTA DOWER COMPANY BEAVER VALLEY POWFR STATION, UNIT NO. 1 DOCKET NO. 50-334 INTRODUCTION As a result of the anticipated-transient-without-scram (ATWS) event at the Salen Nuclear Plant, the Commission imposed a number of reouirements (Generic Letter 83-28) on all plants. The licensee has responded to those reautrements.
The staff has reviewed the license's response to item 4.3, " Automatic Actuation of Shunt Trip Attachment" and has issued letters dated November 8,1984, October 9,1985, and April 3,1986, to document completion of the review. Only technical specifications remain as an open issue.-
The staff's Generic Letter 85-09 specifies technical specification chances applicable to reactor trip system instrumentation and surveillance, and states that technical specification changes should be proposed by licensees to explicitly require independent testing o# the undervoltage and shunt trip attachments of the reactor trip breakers (RTBs) during power operation, testinc of bypass breakers (RTBRs) prior to use, and testing of the RTR and RTBR control room manual switch contacts and wiring during each refueling outaae. These chances have now been incorporated in the Westingbouse Standard Technical Specifications.
EVALUATTON By letter dated October 27, 1986, Duquesne Light Company (the licensee) submitted proposed technical specifications for the Peaver Vallev Power Station, Unit 1.
The proposed changes pertain to the following technical specifications in the Beaver Vallev license:
(1) Table 3.3-1. Functional Unit 21 (Reactor Trip Preakers), Functional Unit 22 (AutomaticTriplogici.
(2) Table 4.3-1, Functional Unit 1 (Manual Reactor Trip), Functional Unit ?1 (Reactor Trio Rreaker), Functional Unit 72 (Automatic Trip Logici and Functional Unit 24 (Reactor Trip Bypass Breaker).

. 1 The; staff has reviewed the. proposed technical specifications for _the above functional units, including the action statements and table notations, and. find L
them consistent with those of Generic Letter PR-09. The proposed chances are
_ therefore acceptable.
-The licensee also proposed a reference addition to Action 2.c.3 of Table 3.3-1, adding the words "per Specification 4.2.a.c."
This change-is of an administrative type consistent with the Westinghouse Standard Technical Specifications and is acceptable.
' ENVIRONMENTAL CONSIDERATION This amendment involves a change in the installation or.use of a facility component located within the restricted area as defined in 10 CFR Part 20.
The staff has determined that the amendment involves no significant increase j
in the amounts, and no significant chanae in the types, of any effluents that may be released offsite, and that there is no sienificant increase in individual or cumulative occupational radiation exoosure. The Commission has r
previously issued a proposed finding that this amendment involves no sionificant hazards consideration and there has been no public comment on such finding. Accordingly, this amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.?2(c)(91 Pursuant to i
10 CFR 51.22(b) no environmental impact statement or environmental assessment need be prepared in connection with the issuance of this amendment.
CONCLUSION' We have concluded, based on the considerations discussed above, that:
(1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, and (2) such activities will be conducted in compliance with the j'
Commission's regulations and the issuance of this amendment _will not be inimical to the common defense and security or to the health and safety of the public.
