NUCLEAR REGULATORY COMMISSION
[Docket No. 50-423]


Northeast Nuclear Energy Co.; Millstone Nuclear Power Station, 
Unit No. 3, 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 (the licensee), for 
operation of the Millstone Nuclear Power Station, Unit No. 3, located 
in New London County, Connecticut.

Environmental Assessment

Identification of the Proposed Action

    The proposed action would relax the setpoint tolerance for the 
pressurizer safety valves and the main steam safety valves from 
<plus-minus>1% to <plus-minus>3%.
    The proposed action is in accordance with the licensee's 
application for amendment dated August 4, 1994.

The Need for the Proposed Action

    The proposed action would revise the setpoint tolerance to assure 
both pressurizer safety valves and main steam safety valves remain 
within technical specification tolerances and reduce the potential for 
filing unnecessary Licensee Event Reports.

Environmental Impacts of the Proposed Action

    The Commission has completed its evaluation of the proposed action 
and concludes that the relaxation of the setpoint tolerance for the 
pressurizer safety valves and the main steam safety valves from 
<plus-minus>1% to <plus-minus>3% is acceptable.
    The change 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 cumulative occupational radiation exposure. 
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 does involve 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. Accordingly, the 
Commission concludes that there are no significant nonradiological 
environmental impacts associated with the proposed action.

Alternatives to the Proposed 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. As an alternative to the proposed action, the staff 
considered denial of the proposed action. Denial of the application 
would result in no change in 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 for the 
Millstone Nuclear Power Station, Unit No. 3.

Agencies and Persons Consulted

    In accordance with its stated policy, the staff consulted with the 
Connecticut State official 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.
    For further details with respect to the proposed action, see the 
licensee's letter dated August 4, 1994, which is available for public 
inspection at the Commission's Public Document Room, The Gelman 
Building, 2120 L Street, NW., Washington, DC, and at the local public 
document room located at the Learning Resource Center, Three Rivers 
Community-Technical College, Thames Valley Campus, 574 New London 
Turnpike, Norwich, CT 06360.

    Dated at Rockville, Maryland, this 28th day of February 1995.

    For the Nuclear Regulatory Commission.
Phillip F. McKee,
Director, Project Directorate I-4, Division of Reactor Projects--I/II, 
Office of Nuclear Reactor Regulation.
