UNITED STATES NUCLEAR REGULATORY COPHISSION CONNECTICUT YANKEE ATOMIC POWER COMPANY DOCKET NO. 50-213 ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The U.S. Nuclear Regulatory Commission (the Commission) is consideririg issuance of schedular exemptions from the requirements of 10 CFR Part 50, Appendix J, to the Connecticut Yankee Atomic Power Company (CYAPC0 or the licensee) for the Haddam Neck Pleat located at the licensee's site in

^

Middlesex County, Connecticut. ,

ENVIRONMENTAL ASSESSMENT Identification of the Proposed Action The proposed action would grant schedular exemptions from the Type C

. testing requirements of Appendix J for the high pressure safety injection system penetration (P-3), and reverse direction testing of the reactor coolant pump seal water return penetration (P-7). The licensee has determined that modifications to the above systems were necessary for the Haddam Neck Plant to meet the requirements of 10 CFR Part 50, Appendix J.

The Need for the Proposed Action One of the conditions of all operating licenses for a water-coolant power reactor, as specified in 10 CFR 50.54(o), is that the primary reactor containment shall meet the containment leakage test requirements set forth in 10 CFR Part 50, Appendix J.

~

In an April 5,1984 letter, the NRC staff noted that not all containment penetrations at the Haddam Neck Plant are tested in accordance with Appendix J.

The staff concluded that it was acceptable to defer implementation of specific Appendix J ana Appendix A modifications until an integrated assessment, i.e..

Integrated Safety Assessment Program (ISAP), could be performed.

In a July 31, 1985 letter, the NRC staff formally established the scope of the Haddam Neck Plant ISAP and designated the Appendix J issues as ISAP Topic 1.03, L Containment Penetration Evaluations. In this letter, tha staff' recognized' that some issues require exemptions to defer action until the Haddam Neck' Plant ISAP could be completed.

By letter dated July 15, 1986, the licensee requested the exemptions presented above.

Environmental Impact of the Proposed Action For the exemption requests that are strictly schedular, the exemptions would allow the current method of testing to continue until all required modifications are completed. The results of the current tests, in conjunction with the overall integrated containment leak rate test, give reasonable assurance that containment integrity will be provided following a postulated eccident.

Thus, radiological releases will not differ from~ those determined previously and the proposed exemptions do not otherwise affect facility radiological effluent or occupational exposures. With regard to potential nonradiological l

impacts, the proposed exemptions do not affect plant nonradiological effluents and have no other environmental impact. Therefore, the Commission concludes i

L ,

there are no measurable radiological or nonradiological environmental inipacts associated with the proposed exemptions.

Alternatives to the Proposed Action:

Since the Commission has concluded there is no measurable environmental impact associated with the proposed exemptions, any alternatives with equal or greater environmental impact need not be evaluated. The principal alternative to the schedular exemptions would be to impose shorter extension periods than requested. Su.h actions would not enhance the protection of the environment and would result in unjustified costs for the licensee.

• Alternative Use of Resources This action does not involve the use of resources not considered previously in the Final Environmental Statement for Haddam Neck.

Agencies and Persons Consulted:

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

b FINDING OF NO SIGNIFICANT IMPACT The Conunission has determined not to prepare an environmental impact statement for the proposed exemptions. Based upon the environmental assessment, t 1

~ the NRC staff concludes that the proposed action will not have a significant effect on the quality of the human environment.
