t 7590-01 UNITED STATES NUCLEAR REGULATORY COMMISSION DUQUESNE LIGHT COMPANY DOCKET NO. 50-334 NOTICE OF CONSIDERATION OF ISSUANCE OF AMENDMENT TO FACILITY OPERATING LICENSE AND PROPOSED NO SIGNIFICANT HAZARDS CONSIDERATION DETERMINATION The U.S. Nuclear Regulatory Comission (the Commission) is considerin9 issuance of an amendment to Facility Operating License No. DPR-66 issued to Duquesne Light Company (the licensee) for operation of the Beaver Valley Power Station, Unit 1 located in Shippingport, Pennsylvania.
The proposed amendment would revise the Technical Specifications to provide operability requirements, limiting conditions of operation and surveillance requirements on the habitability systems for the combined Unit 1 and Unit 2 control room. These revisions to the Technical Specifications would be made in response to the licensee's application for amendment dated October 9, 1986 and r.odified by revisions dated February 3, 1987 and April 16, 1987.
, The October 9,1986 amendment reouest was initially noticed on December 17, 1986 (51 FR 45198). This request included a proposal to remove the specifications for the Unit 2 fire detection instruments that are currently in the Unit 1 Technical Specifications. Subseouently, this request has beer, withdrawn. The specifications for fire detection instruments will be handled in a future separate action. In addition, it was detennined that the operability recuirements, Limiting Conditions of Operation and surveillance requirements for the Unit 2 habitability systems must be included in the l 8705100171 DR 870430 ADOCK 05000334 l PDR

T Unit 1 Technical Specifications. The earlier notice had indicated that these specifications would be addressed only in the Unit 2 licerse. Because of these changes, this recuest for a license amendment is being renoticed.
Before issuance of the proposed license amendment, the Commission will have made findings recuired by the Atomic Energy Act of 1954, as amended (the Act) and the Commission's regulations.
The Commission has made a proposed determination that the request for amendment involves no significant hazards consideration. Under the Commission's regulations in 10 CFR 50.92, this means that operation of the facility in accordar.ce with the proposed amendment would not (1) involve a significant increase in the probability or consequences of an accident previously evaluated; or (2) create the possibility of a new or different kind of accident from any accident previously evaluated; or (3) involve a significant reduction in a margin of safety.
The modifications to the Unit I systems and the additions to the Unit 2 systems do not reduce the level of control room habitability under postulated accident conditions; thus ensuring no increase in the probability cf occurrerce or the consequences of an accident previously analyzed. Neither the addition of two independent trains of ventilation systems associated with Unit 2 nor increasing the capacity of the Unit I habitability systems, create the possibility of a new or different kind of accident. Furthermore, the mcdifications are made to maintain the same level of habitability in the combined control room as in the current Unit I control room, thus the current margin of safety will not be reduced.
Therefore, based on these considerations, the Commission has made a proposed determinaticn that the amendment recuest involves no significant hazard considerations.
c y ,
The Conraission has determined that-failure to act in a timely way would result in extending the shutdown of Beaver Valley, Unit I required to make the:e modifications. Therefore, the Commission has insufficient time to issue its usual 30-day notice of the proposed action for public comment.-
4 If the proposed determination becomes final, an opportunity for a hearing will be published in the FEDERAL REGISTER at a later date and any hearing request will not delay the effective date of the amendment.
If the Commission decides in its final determination that the amendment does involve a significant hazards consideration, a notice of opportunity for a prior hearing will be published in the FEDERAL REGISTER, and, if a hearing is granted, it will be held before any amendment is issued.
The Concission is seeking public comments on this proposed determinaticn of no significant hazards consideration. Comments on the proposed determinaticn may be telephered to John F. Stolz, Pro.iect Director, Project Directorate .I-4, by collect call to (301-492-7040) or submitted in writing to the Rules and Procedures Branch, Division of Rules and Records, Office of Administration, Washington, DC. All comments received by May 19, 1987, will be considered in reaching a final determination. A copy of the application and any comments received may be examined at the Commission's Public Document Room, 1717 P Street, N.W., Washington, DC, and at the B.F. Jones Memorial Library, 663 Franklin Avenue, Aliquippa, Pennsylvania 15001.
Dated at Bethesda, Maryland, this 30th day of April,1987.
