t 7590-01 UNITED STATES NUCLEAR REGULATORY COMMISSION
((0RTHEAST NUCLEAR ENERGY COMPANY DOCKET NO. 50-423 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-49 issued to-Northeast Nuclear Energy Company, et al. (the licensee), for operation of the Millstone Nuclear Power Station, Unit No. 3 located in New London County, Connecticut.
Identification of the ProDosed Action:
The proposed amendment would revise the Technical Specifications to
(
extend the required surveillance testing for the emergency diesel generators l
on a one-time basis so that they are required to be tested by the 1993 refueling outage, but no later than September 30, 1993, rather than by l-December 25, 1992, which is now required.
The proposed amendment is in accordance with Northeast Nuclear Energy Company's application dated October 22, 1992.
Need for the Prooosed Actign:
The proposed change to the Facility Operating License is needed to extend the interval for diesel generator surveillance because the currently required interval would require an unscheduled outage of the plant.

l Environmental Imoacts of the Proposed Action:
The Commission has completed its evaluation of the proposed revision to Technical Specification Section 4.8.1.1.2.g.l.
The proposed revision would extend the required surveillance testing of the emergency diesel generators on a one-time basis so that they are required to be tested by the 1993 refueling outage, but no later than September 30, 1993, rather than by December 25, 1992, which is now required.
Based on itr. review, the Commission concludes that the proposed change is acceptable.
The staff has determined that the proposed change does not alter any iritial conditions assumed for the design basis accidents previously evaluated nor change operation of safety systems utilized to mitigate the design basis accidents.
The proposed change does 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 cumulative occupational radiation exposure. Accordingly, the
~
Commission concludes that the proposed action would result in no significant radiological environmental impact.
With regard to potential nonradiological impacts, the proposed change involves components in the plant which are located within the restricted area as defined in 10 CFR Part 20.
It does not affect nonradiological plant effluents and has no other environmental impacts.
Therefore, the Commission concludes that there are no significant nonradiological environmental impacts associated with the proposed amendment.
. Alternatives to the Prooosed Action:
Since the Commission concluded that there are no significant environmental effects that would result from the proposed actions, any alternatives with equal or greater environmental impacts need not be evaluated.
Alternative Use of Resources:
The action would involve no use of resources not previously considered in the Final Environrnental Statement (FES) for the Millstone Nuclear Power Station, Unit 3.
Agencies and Persons Consulted:
The NRC staff reviewed the licensee's 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 amendment.
Based upon the foregoing environmental assessment, the Commission concludes that the proposed action will not have a significant effect on the quality of the human environment.
For further details with respect to this action, see the application for amendment dated October 22, 1992, which is available for public inspection at the Commission's Public Document Room, the Gelman Building, 2120 L Street, NW., Washington, DC 20555, and at the local public document room located at I
