e UNITED STATES NUCLEAR REGULATORY COMMISSION PECO ENERGY COMPANY DOCKET NO. 50-353 LIMERICK GENERATING STATION. UNIT 2 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 No. NPF-85, issued to PECO Energy Company (the licensee), for operation of the Limerick Generating Station (LGS), Unit 2, located in Montgomery and Chester Counties, Pennsylvania.
ENVIRONMENTAL ASSESSMENT Identification of the Proposed Action:
The proposed action would approve the implementation of a plant modification to support the installation of replacement suction strainers for the emergency core cooling systems (residual heat removal and core spray) pumps at LGS, Unit 2.
The proposed action is in accordance with the licensee's application for amendment dated October 6,1997, as supplemented by letter dated August 28,1998.
The Need for the Proposed Action:
On May 6,1996, the NRC issued NRC Bulletin 96-03, " Potential Plugging of Emergency Core Cooling Suction Strainers by Debris in Boiling Water Reactors," that requested addressees to implement appropriate procedural measures and plant modifications to minimize the potential for clogging of emergency core cooling system (ECCS) suppression pool suction strainers by debris generated during a loss-of-coolant accident (LOCA) and requested that addressees report to the NRC whether they intend to implement the requested actions.

2-In response to the above cited bulletin, the licensee proposed a plant modification to i
install replacement suction strainers in the ECCS pumps. The replacement strainer surface areas, which are substantially larger than the currently installed strainers, are required to reduce potential strainer clogging due to debris in the suppression pool following a postulated loss-of coolant accident.
EnvironmentalImpacts of the Proposed Action:
The Commission has completed its evaluation of the proposed action and concludes
- that the installation of the replacement strainers in the ECCS pumps reduces potential strainer clogging due to debris in the suppression pool following a loss-of-coolant accident and does not change the manner in which the plant is being operated or the environmental impacts of
- operation. The proposed action involves features entirely within the protected area as defined in 10 CFR Part 20.
The proposed action will not increase the probability or consequences of accidents, no changes are being made in the types of any effluents that may be released offsite, and there is no significant increase in the allowable individual or public radiation exposure. Therefore, there are no significant radiological environmental impacts associated with the proposed action.
With regard to potential nonradiological impacts, the proposed action does not involve any historic sites and only involves features located entirely within the restricted area as defined in 10 CFR Part 20. It does not affect nonradiological plant effluents and has no other environmental impact. Therefore, there are no significant nonradiological environmental impacts associated with the proposed action.

Accordingly, the Commission concludes that there are no significant nonradiological environmental impacts associated with the proposed action.
Alternatives to the Proposed Action:
As an altemative to the proposed action, the staff considered denial of the proposed action (i.e., the "no-action" attemative). Denial of the application would result in no change in current environmentalimpacts. The environmentalimpacts of the proposed action and the altemative action are similar, Altemative Use of Resources:
This action does not involve the use of any resources not previously considered in the Final Environmental Statement for the Limerick Generating Station, Unit 2.
Aaencies and Persons Consulted; In accordance with its stated policy, on October 29,1998, the staff consulted with the Pennsylvania State official, Mr. David Ney of the Bureau of Radiation Protection, regarding the environmentalimpact of the proposed action. The State official had no comments.
FINDING OF NO SIGNIFICANT IMPACT Based upon tne 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 environmentalimpact statement for the proposed action.
For further details with respect to the proposed action, see the licensee's letter dated October 6,1997, as supplemented by letter dated August 28,1998, which are available for l
