7590-01 UNITED STATES NUCLEAR REGULATORY COMMISSION PUBLIC SERVICE ELECTRIC & GAS COMPANY PHILADELPHIA ELECTRIC COMPANY QELMARVA POWER AND LIGHT COMPANY ATLANTIC CITY ELECTRIC COMPANY SALEM NUCLEAR GENERATING STATION. UNITS 1 AND 2 DOCKET NOS. 50-272 AND 50-311 ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The U.S. Nuclear Regulatory Commission (the Commission) is considering issuance of an amendment to Facility Operating License Nos. DPR-70 and DPR-75, issued to Public Service Electric & Gas Company (PSE&G, the licensee), for operation of the Salem Nuclear Generating Station, Units 1 and 2 (Salem Units 1 and 2).
The facility consists of two pressurized water reactors located at the licensee's site in Salem County, New Jersey.
ENVIRONMENTAL ASSESSMENT Identification of Proposed Action:
The proposed action would change Technical Specification Table 3.3-5,
" Engineered Safety Features Response Time," to extend the Containment Fan Cooler Unit (CFCU) response time from 45 to 60 seconds.
The proposed action is in accordance with the license's application for amendment dated October 25, 1996, as supplemented by letters dated December 11, 1996, January 28, March 27, and April 24, 1997.

l e The Need for the Proposed Action:
l The proposed action is needed to ma,ke the Techrjical Specifications l
(TSs) consistent with the as-built plant. The as-built plant has a longer response time for the CFCUs than that identified in the TSs because (1) a 1976 plant modification added time delays to valves that isolate non-essential service water loads in response to an accident signals, and (2) the licensee failed to consider the impact of CFCU service water outlet valve sequencing delays on overall post-accident system performance.
The 1976 modification was implemented to limit the potential for water hammer of the service water f
system during the isolation of the non-essential loads.
Environmental Imoacts of the Proposed Action:
l l
The radiological environmental impact of the proposed action has already been evaluated and approved by the staff.
In support of Amendment No. 190 for Unit I and Amendment No. 173 for Unit 2, issued February 6, 1997, the staff l
performed its own analysis of the offsite doses resulting from a Loss of 1
Coolant Accident.
The staff's analysis was performed using the CFCU response time in the proposed action and the staff concluded that the offsite doses are within the applicable dose acceptance criteria of 10 CFR Part 100.
Accordingly, the Commission concludes that there are no significant radiological environmental impacts associated with the proposed action.
With regard to potential nonradiological impacts, the proposed action involves features located entirely within the restricted area as defined in 10 CFR Part 20.
It does not affect nonradiological plant effluent and has no other environmental impact. Accordingly, the Commission concludes that there
._m_
5 are no significant nonradiological environmental impacts associated with the proposed action.
81.ternatives to the Prooosed Action:
Since the Commission has concluded there is no measurable environmental impact associated with the proposed action, any alternatives with equal or greater environmental impact need not be evaluated. The principal alternative to the action would be to deny the request.
Such action would not change any
. current environmental impacts. The environmental impacts of the proposed action and the alternative action are similar.
Alternative Use of Resources:
This action does not involve the use of any resources not previously considered in the " Final Environmental Statement re, lated to the operation of Salem Nuclear Generating Station Units 1 and 2," dated April 1973.
Aaencies and Persons Consulted:
In accordance with its stated policy, on April 14, 1997, the staff consulted with the New Jersey State official, Richard Pinney, of the Department of Environmental Protection, regarding the environmental impact of the proposed action. The State official had no comments.
- FINDING OF NO SIGNIFICANT IMPACT Based upon the environmental assessment, the Commission concludes that the proposed action will not have a significant effect on the quality of the human environment. Accordingly, the Commission has determined not to prepare an environmental impact statement for the proposed action.
