7590-01 UNITED STATES NUCLEAR REGULATORY' COMMISSION WISCONSIN ELECTRIC POWER COMPANY DOCKET NO. 50-266 NOTICE OF ENVIRONMENTAL ASSESSMENT AND FINDING 0F NO SIGNIFICANT IMPACT J

TheU.S.NuclearRegulatoryCommission(theCommission)isconsidering issuance of relief from the requirements of Section XI of the ASME Boiler and Pressure Vessel Code as specified by the provisions of 10 CFR 50.55a(b) to Wisconsin-Electric Power Company (the licensee), for the Point Beach Nuclear j

Plant Unit No. 1, located in the Town of Two Creeks, Manitowoc County, Wisconsin.

ENVIRONMENTAL ASSESSMENT Identification of Proposed Action:

The action would provide relief from the requirement to perform surface examinations of the safety injection reducer-to-safe end welds as required by Section XI of the ASME Boiler and Pressure Vessei 4

Code which has been incorporated by reference in the requirements of 10 CFR 50.55a relating to Inservice Inspection of Safety Related Components. Volumet-ric examinations of these welds would be performed every 10 years as required.

The Need for the Proposed Action:

The proposed relief is required because sur-face examinations of these welds are not possible due to the inaccessibility of the weld surfaces. The welds are located between the reactor vessel and the biological shield wall.

Environmental Impacts of the Proposed Action: The proposed relief is allowed

-by the provisions of 10 CFR 50.55a(g)(6)(i) where the tests or examinations required by the code are determined impractical to perform. As the surfaces of

-the welds in question are inaccessible, a surface examination has been determined I

by the licensee and evaluated by the Commission as impractical to perform. The 8409110274 840827 PDR ADOCK 05000266 P

PM

. has' determined that the required volumetric inspection of the welds once every 10 years will provide adequate assurance of the structural integrity of the welds.

Identical relief to that requested for Unit I was provided for Point Beach Unit 2 by the Commission's Safety Evaluation and letter of March 29, 1984.

Consequently, as the Commission has determined that the welds will retain adequate structural integrity utilizing the licensee's proposed alternate examination (volumetric examination once every 10 years), the probability of weld failure has not been increased significantly and the consequences of post-weld failure radiological releases will not be greater than previously determined nor does the requested relief otherwise affect radiological plant effluents. Therefore, the Commission has determined that there are no significant radiological environmental impacts associated with the requested relief.

With regard to potential non-radiological impacts, the requested relief involves features located entirely within the restricted area as defined in 10 CFR Part 20.

It does not affect non-radiological plant effluents and has no other non-radiological environmental impact. Therefore, the Commission has determined that there are no significant non-radiological environmental I

impacts associated with the requested relief.

Alternative Use of Resources: This action involves no use of resources not l

considered in the Final Environmental Statement (constructfor permit and opera-ting license) for the Point Beach Nuclear Plant Unit No. 1.

Alternative Use of Resources:

This action involves no use of resources not considered in the Final Environmental Statement (construction pemit and opera-ting license) for the Point Beach Nuclear Plant Unit No. 1.

Agencies and Persons Consulted: The NRC staff reviewed the licensee's request

- and did consult other agencies or persons.

FINDING OF NO SIGNIFICANT IMPACT:

The Commission has determined not to prepare an environmental impact statement for the requested relief.

Based upon the foregoing environmental assessment, we conclude that the proposed action will not have a significant effect on the quality of the human environment.

Mann Public Library,1516 Sixteenth Street, Two Rivers, Wisconsin.
