' 7590-01 UNITED STATES NUCLEAR REGULATORY COMMISSION CONNECTICUT YANKEE ATOMIC POWER COMPANY DOCKET NO. 50-213 ENVIRONMENTAL ASSESSMENT AND FINDING 0F NO SIGNIFICANT IMPACT The U. S. Nuclear Regulatory Commission (the Commission) is considering issuance of an amendment to Facility Operating License No. DPR-61, issued to Connecticut Yankee Atomic Power Company (CYAPC0, the licensee), for operation of the Haddam Neck Plant, located in Middlesex County, Connecticut.

ENVIRONMENTAL ASSESSMENT Identification of Proposed Action:

The proposed amendment would provide new Technical Specifications (TS) and revisions to existing TS that provide limiting conditions for operation (LC0) and surveillance requirements in response to Generic Letter 83-37, as applicable to the Haddam Neck Plant. TS have been proposed for the following:

1) Post-Accident Sampling, 2) Sampling and Analysis of Plant Effluents, 3)

Containment Pressure Monitor, 4) Reactor Coolant System Vents, 5) Noble Gas Effluent, 6) Containment High-Pange Radiation Monitor, and 7) Instrumentation for Detection of Inadequate Core Cooling.

The proposed action is in accordance with the licensee's application for amendment dated July 1, 1988 with revisions by letters dated December 2, 1988 and March 1, 1989.

The Need for the Proposed Action:

The proposed change to the TS is required in order for the licensee to l comply with Generic Letter (GL) 83-37, "NUREG-0737 Technical Specifications,"

dated November 1,1983.

, Environmental Impacts of the Proposed Action:

The Commission has completed its evaluation of the proposed revisions to the TS. The proposed revisions would provide TS for those items identified in NUREG-0737, " Clarification of TMI Action Plan Requirements," as requiring TS. TS have been proposed for all items found applicable to Haddam Neck per GL-83-37 except Long Tem Auxiliary Feedwater System Evaluation (II.E.I.I), Containment Water Level Monitor (II.F.1.5), Containment Hydrogen Monitor (II.F.I.6) and Control Room Habitability Requirements (II.D.3.4). The TS for these items will be l

resolved in other programs such as the Integrated Safety Assessment Program (ISAP) and the TS Upgrade Program. The addition of these new TS and revisions to certain existing TS would not increase the probability or consequences of i 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 i or cumulative occupational radiation exposure. Accordingly, the Connission concludes that this action would result in no significant impact.

With regard to potential non-radiological impacts, the proposed changes to the TS involve systems located within the restricted area as defined in 10 CFR Part 20. It does not affect non-radiological plant effluents and has no other environmental impact. Therefore, the Commission concludes that there are no significant non-radiological environmental impacts associated with the proposed amendment.

The Notice of Consideration of Issuance of Amendment and Opportunity for Hearing in connection with this action was published in the Federal Register on November 2, 1988 (53 FR 44263). No request for hearing or petition for leave to intervene was filed following this notice.

., Alternative to the Proposed Action:

It has been detennined that there is no measurable impact associated with the proposed amendment; any alternatives to the amendment will have either no environmental impact or greater environmental impact.

Alternative Use of Resources:

This action does not involve the use of any resources beyond the scope of resources used during nonnal operation.

FINDING OF NO SIGNIFICANT IMPACT Based upon the foregoing environmental assessment, the Commission concluded 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 license amendment.

For further details with respect to this action, see the request for amendment dated July 1, 1988 with revisions dated December 2, 1988 and March 1, 1989. Copies of the request for amendment are available for public -

inspection at the Commission's Public Document Room, the Gelman Building, 2120 L Street, N.W., Washington, D.C. and at the Russell Library, 123 Broad Street, Middletown, Connecticut.

Dated at Rockville, Maryland, this 20th day of April 1989.
