7590-01 UNITED STATES NUCLEAR REGULATORY COMMISSION
-THE CLEVELAND ELECTRIC ILLUMINATING COMPANY, ET AL.
DOCKET 50-440 ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The U. S. Nuclear Regulatory Comission (the Comission) is considering issua'nce of an amendment to Facility Operating License No. NPF-58, issued to The Cleveland Electric Illuminating Company, Duquesne Light Company, Ohio Edison Company, Pennsylvania Power Company and Toledo Edison Company (the licensees), for operation of the Perry Nuclear Power Plant, Unit No.1, located in Lake County, Ohio.
ENVIRONMENTAL ASSESSMENT Identification of Proposed Action The proposed anendment would revise Tables 3.6.4.1 and 3.3.7.4-1 4
of the Technical Specifications (TS) to add two aoditional automatic containment isolation valves to the Containment Isoletion Valve Table and one valve control switch to the Division 1 Remote Shutdown System Control Table.
The valves are being added to separate the suppression Pool Cleanup System from the residual Heat Removal System.
The proposed action is in accordanc.e with the ifcensees' application for amendment dated January 18, 1989.
The Need for the Proposed Action The proposed change to the TS is required in order to provide the licensees the ability to operate the Suppression Pool Cleanup System without 8905240443 890516 ADOCK0500g40 DR
r 2
l causing a residual heat' removal (RHR) subsystem to become inoperable.
Presently, the return of the Suppression Pool Cleanup System ties into either. loop A or loop B of the RHR system upstream of the suppression pool isolation valve. Opening this valve in the respective RHR loop drops 4 pressure below the low pressure alarm setpoint rendering that loop inoperable.
Environmental Impacts of the Proposed Action The Comission has completed its evaluation of the proposed revision to the TS and concludes that the proposed additional isolation valves and piping provide single failure proof, seismic Category I ouality, appropriate valve closure time, remote control shutdown capability and leak tight barrier by a water seal for at least 30 days during an accident. Accordingly, the Comission concludes that this proposed action would result in no significant radiological environmental impact.
The Notice of Consideration of Issuance of Amendment and Opportunity for Prior Hearing in connection with this action was published in the Federal Register on March 20,1989(54FR11463). No request for hearing or petition for leave to intervene was filed following this notice.
With regard to potential nonradiological impacts, the proposed change to the TS involves the addition of two containment isolation valves to the Suppression Pool Cleanup System.
It does not affect nonradiological plant effluents and has no other environmental impact.
1, l.
.. l Therefore, the Comission concludes that there are no significant nonradio-logical environmental impacts associated with the proposed amendment.
Alternative to the Proposed Action Since the Connission concluded that there are no significant environmental effects that would result from the proposed action, any alternatives with equal or greater environmental impacts need not be evaluated.
The principal altern6tive would be to deny the requested amendment.
This would not reduce environmental impacts of plant operation and would result in reduc.ed operational flexibility.
Alternative Use of Resources This action coes nut involve the use of any resources not previously considered in the Final Environmental Statement related to the operation of the Perry Nuclear Power Plant, Units 1 and 2, dated August 1987.
Agencies and Persons Consulted i
The NRC staff reviewec the licensees' request and did not consult other agencies or persons.
FINDING 0F NO SIGNIFICANT IMPACT The Commission has determined not to prepare an environmental impact statement for the proposed license amendment.
Based upon the foregoing environmental assessnent, we conclude that the proposed action will not have a significant effect on the quality of the human environment.
