UNITED STATES NUCLEAR REGULATORY COMMISSION NORTHEAST NUCLEAR ENERGY COMPANY, ET Al DOCKET NO. 50-245 ENVIRONMENTAL ASSESSMENT AND FINDING OF N0 SIGNIFICANT IMPACT The U.S. Nuclear Regulatory Commission (the Commission) is considering issuance of an exemption from the schedular requirement of 10 CFR 50.71(e)(3)

(ii) to the Northeast Nuclear Energy Company (NNECo) (the licensee) for the Millstone Nuclear Power Station, Unit No. 1, located at the licensee's site in New London County, Connecticut.

ENVIRONMENTAL ASSESSMENT Identification of Proposed Action:

The proposed action would grant an exemption from the requirements of 10 CFR 50.71(e)(3)(ii) to submit an updated Final Safety Analysis Report (FSAR) for the Millstone Unit I within 24 months of receipt of a letter notifying the licensee that the systematic evaluation program has been completed. By letter dated March 16, 1983, the staff informed NNECo that the systematic evaluation program had been completed for Millstone Unit 1 and that, pursuant to

"^

10 CFR 50.71(e)(3), the licensee was reouired to file an updated FSAP. By letter dated February 4,1985, the licensee requested an exemption to defer submittal of the updated FSAR for Millstone Unit 1. By letter dated April 11, 1985, the staff issued an exemption to 10 CFR 50.71(e)(3) for Millstone Unit 1 permitting a 6 month extension from the date of issuance of the exemption for submittal of the updated FSAR. Any additional exemptions to 10 CFR 50.71 would be grarted by the Director of Licensing, ONRR, only upon review and approval 8511220506 851112 PDR ADOCK 05000245 P PDR

a of a program plan for the submittal of an updated FSAR. By letter dated September 13, 1985, the licensee requested an additional exemption to defer submittal of the updated FSAR for Millstone Unit 1. However, by letter dated October 2,- 1985, the staff notified NNEco that its request for an additional exemption was being denied because the licensee's request was not responsive to the terms identified in the exemption issued on April 11, 1985. By letter

' dated October 11, 1985, NNEco resubmitted a request for an exemption from the schedular requirements of 10 CFR 50.71(e)(3)(ii) that contained the schedular information required. The deferral of the submittal of the updated FSAR is the proposed action be_ing considered by the staff.

~

The Need for the Proposed Action -

For most plants covered by 10 CFR 50.71(e)(3)(ii), ample time was available for updating the FSAR within the 24-month interval allowed in the regulations. However, Millstone Unit I requested participation in an expanded ass'essment of outstanding regulatory requirements with the idea of establishing an integrated schedule for the completion of these issues in a resource efficient manner.

The licensee has other ongoing activities which would directly affect the quality and substance of an updated FSAR. For example, the staff is now implementing a limited Integrated Safety Assessment Program (ISAP) for Millstone Unit 1. The purpose of ISAP is to prioritize outstanding NRC requirements and licensee initiatives resulting in an integrated living schedule and will serve as a basis upon which future regulatory requirements

i can be judged. The licensee believes that these additional efforts will facilitate a better understanding of the plant design bases when the updated FSAR is submitted.

The licensee in its October 11, 1985, exemption request identified the milestones for the completion of the FSAR update as required in the April 11, 1985 exemption.

In this exemption request the licensee requested relief from the required completion date until March 31, 1987.

e' Environmental Impacts of the Proposed Action:

The proposed exemption affects only the required date for updating the FSAR and does not affect the risk of facility accidents. Thus, post-accident I

radiological releases _ will not differ from those determined previously, and the proposed exemption does not otherwise affect facility radiological impacts, the proposed exemption does not affect plant non-radiological effluents and has no other environmental impact. Therefore,'the Commission l concludes there are no measurable radiological or nonradiological environmental

! impacts associated with the proposed exemption.

Alternatives to the proposed Action:

l Since the Commission has concluded there is no measurable environmental impact associated with the proposed exemption, any alternatives with equal or greater environmental impacts need not be evaluated. The principal alternative to the exemption would be to require an earlier date for submittal i

.4

-4 of the updated FSAR. Such an action would not enhance the protection of the environment and would result in unnecessary diversion of utility engineering resources from other work of higher safety significance.

Alternative Use of Resources:

.This action does not involve the use of resources not considered previously in the Final Environmental Statement for Millstone Unit 1.

Agencies and Persons Consulted:

The NRC staff res:dwed the licensee's request and did not consult other agencies or persons.

FINDING OF NO SIGNIFICANT IMPACT The Commission has determined not to prepare an environmental impact statement for the proposed exemption. Based upon the environmental assessment, the NRC staff concludes that the proposed action will not have a significant effect on the quality of the human environrent.

For further details with respect to this proposed action, see the licensee's letter dated October 11, 1985. This letter is availtale for public inspection at the Commission's Public Document Room,1717 H Street, r

N.W., Washington, D.C., and at the Waterford Public Library, 49 Rope Ferry Road, Waterford, Connecticut 06385.

Dated at Bethesda, Maryland, this 12th day of November 1985.
