i UNITED STATES NUCLEAR REGULATORY COMMISSION CONNECTICUT YANKEE ATOMIC POWER COMPANY DOCKET NO. 50-213 ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The U.S. Nuclear Regulatory Comission (the Comission) is considering issuance of an exemption from the schedular requirement of 10 CFR 50.71(e)(3)
(ii) to the Connecticut Yankee Atomic Power Company (CYAPCo) (the licensee) for the Haddam Neck Plant, located at the licensee's site in Middlesex 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 Facility Description and Safety Analysis (FDSA) for the Haddam Neck Plant within 24 months of receipt of a letter notifying the licensee that the systematic evaluation program has been completed. By letter dated July 20, 1983, the staff informed CYAPCo that the systematic evaluation program had been completed for the Haddam Neck Plant and
^
that, pursuant to 10 CFR 50.71(e)(3), the licensee was required to file an updated FDSA. By letter dated February 4,1985, the licensee requested an exemption to defer submittal of the updated FDSA for the Haddam Neck Plant.
By letter dated April 11, 1985, the staff issued an exemption to 10 CFR 50.71(e)(3) for the Haddam Neck Plant permitting a 6 month extension from the date of issuance of the exemption for submittal of the updated FDSA.
Any additional exemptions to 10 CFR 50.71 would be granted by the Director 8b11220240 851112 PDR ADOCK 05000213 P
,- of Licensing, ONRR, only upon review and approval of a program plan for the submittal of an updated FDSA. By letter dated September 13, 1985, the licensee requested an additional exemption to defer submittal of the updated FDSA for the Haddam Neck Plant. However, by letter dated October 2, 1985, the staff notified CYAPCo 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, CYAPCo 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 FDSA is the proposed action being considered by the staff.
4 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 FDSA within the 24-month interval allowed in the regulations. However, the Haddam Neck Plant requested participation in an expanded assessment 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 FOSA.
For example, CYAPCo is contracting with Westinghouse to develop and document detailed information on the design and licensing bases for key systems at the Haddam Neck Plan.
CYAPCo has also undertaken an extensive design bases reanalysis which will i
i !
j result in new analyses for all FDSA Chapter 10 transients and accidents for several systematic evaluation program topics. Also, the staff is now implementing a limited Integrated Safety Assessnent Program (ISAP) for the Haddam Neck Plant. 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 can be judged. The licensee believes that these additional efforts will facilitate a better understanding of the plant design bases when the updated FDSA is submitted.
A The licensee in its October 11, 1985, exemption request identified the milestones for the completion of the FDSA update as required in the April 11, 1985 exemption.
In this exemption request the licensee requested relief from the required completion date until June 30, 1987.
Environmental Impacts of the Proposed Action:
The proposed exemption affects only the required date for updating the FDSA and does not affect the risk of facility accidents. Thus, post-accident radiological releases will not differ from those determined previously, and 1
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 concludes there are no measurable radiological or nonradiological environmental impacts associated with the proposed exemption.

Alternatives to the Proposed Action:
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 of the updated FDSA. 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 the Haddam Neck Plant.
Agencies and Persons Consulted:
The NRC staff reviewed 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 environment.
. For further details with respect to this proposed action, see the licensee's letter dated October 11, 1985. This letter is available for public inspection at the Comission's Public Document Room,1717 H Street, N.W., Washington, D.C., and at the Russell Library,123 Broad Street, Middletown, Connecticut 06547.
Dated at Bethesda, Maryland, this 12th day of November 1985.
