UNITED STATES NUCLEAR REGULATORY COMMISSION NORTHEAST NUCLEAR ENERGY COMPANY DOCKET NO. 50-245 ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The U.S. Nuclear Regulatory Comission (the Commission) is considering issuance of an amendment to an exemption from the requirements of 10 CFR Part 50, Appendix J, Paragraph III.C.1 issued to the Northeast Nuclear Energy Company (NNECO or the licensee) for Millstone Nuclear Power Station, Unit 1, located in New London County, Connecticut.
ENVIRONMENTAL ASSESSMENT Identification of the Proposed Action:
The proposed action would correct an administrative error. The exemption, which was issued on June 5, 1991, granted exemptions for Penetrations X-25, X-26, X-202E and X-205 frim the local leak test (Type C) requirements of 10 CFR Part 50, Appendix J,Section III.C.1. The NRC staff concluded that the proposed alternative test procedures are the most conservative with the existing configuration and will test both valve seals to provide indication of the leak tightness of the containment boundaries.
In a letter dated April 15, 1993, NNECO stated that one of the penetrations was not correctly identified, penetration X-202E should have been X-2020, and requested that the exemption be corrected.
The Need for the Proposed Action:
The proposed exemption araendment is needed to correctly identify the i
subject penetration.

s Environmental ImDacts of the Proposed Action:
i The proposed exemption amendment corrects a misidentified penetration i
and, therefore, does not have any environmental impact.
In the June 5, 1991, exemption, Penetration X-202E should have been X-202D.
Penetration X-202E is for a vacuum breaker (torus to drywell) and does not require 10 CFR Part 50, i
Appendix J testing.
Thus, radiological releases will not differ from those determined previously and the proposed exemption amendment does not otherwise affect facility radiological effluents or occupational exposures. With regard to potential nonradiological impacts, the proposed exemption amendment does not affect plant nonradiological effluents and has no other environmental impact.
i Therefore, the Commission concludes there are no measurable radiological or nonradiological environmental impacts associated with the proposed exemption amendment.

Alternatives to the Proposed Action:
l Since the Commission has concluded there is no measurable environmental impact associated with the proposed exemption amendment, any alternative to f
this amendment will have either no significant different environmental impact.
or greater environmental impact. The principal alternative would be to deny l
the exemption amendment requested. Such action would not enhance the l
aa protection of the environment and would result in the misidentification 'of the l
.j Alternative Use of Resources:
This action does not involve the use of resources not considered i
i previously in the Final Environmental Statement for Millstone Nuclear Power i

Aaencies and Persons Consulted:
The NRC staff reviewed the licensee's request and did not consult other agencies or persons.
FINDING OF NO SIGNIFICANT IMPACT Based on the foregoing environmental assessment, the Comission concludes that the proposed action will not have a significant effect on the quality of the human environment. Accordingly, the Comission has determined not to prepare an environmental impact statement for the proposed exemption amendment.
For further details with respect to this proposed action, see the licensee's letter dated April 15, 1993, which is available for public inspection at the Comission's Public Document Room, the Gelman Building, 2120 L Street, NW., Washington, DC 20555, and at the local public document room located at the Learning Resources Center, Thames Valley State Technical College, 574 New London Turnpike, Norwich, Connecticut 06360.
