7590-01 UNITED STATES NUCLEAR REGULATORY COMMISSION SOUTHERN CALIFORNIA EDISON COMPANY SAN DIEGO GAS AND ELECTRIC COMPANY DOCKET NO. 50-206 SAN ONOFRE NUCLEAR GENERATING STATION, UNIT NO. 1 ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The U. S. Nuclear Regulatory Commission (the Commission) is considering issuance of an amendment to Provisional Operating License No. DPR-13 issued to Southern California Edison Company, et al., (the licensee), for operation of San Onofre Nuclear Generating Station, Unit No. 1, located in San Diego County, California.
ENVIRONMENTAL ASSESSMENT Identification of Proposed Action:
The proposed amendment is a request to revise Sections 2, 3 and 4 of the Appendix A Technical Specifications to be consistent with a replacement upgrade of the San Onofre Nuclear Generating Station, Unit 1 Nuclear Instrumentation System (NIS). The modification would consist of a complete replacement of the NIS detectors, cabling, and signal processing equipment. Certain existing output devices and cable routing would be retained. The licensee stated that the proposed revisions to the technical specifications would assure appropriate limiting conditions for operation and surveillance requirements for the upgraded NIS. The safety analyses of transients and accidents are reviewed in the application. Because the new NIS detectors are not symmetrical with respect to the reactor, a revised dropped control rod analysis is presented which is the analysis most affected by the upgraded nuclear instrumentation system.
-2 The Need for the Proposed Action: The proposed amendment is required to permit the licensee to replace the Nuclear Instrumentation System.
Environmental Impacts of the Proposed Action: The proposed action would not involve a significant change in the probability or consequences of any accident previously evaluated, nor does it involve a new or different kind of accident.
Consequently, any radiological releases resulting from an accident would not be significantly greater than previously determined. The proposed amendment does not otherwise affect routine radiological plant effluents. Therefore, the Commission concludes that there are no significant radiological environmental impacts associated with the proposed amendment. The Commission also concludes that the proposed action will not result in a significant increase in individual or cumulative occupational radiation exposure.
With regard to nonradiological impacts, the proposed amendment does not affect nonradiological plant effluents and has no other environmental impact.
Therefore, the Commission concludes that there are no significant nonradiological 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 May 18, 1988 (53 FR 17809). No request for hearing or petition for leave to intervene was filed following this notice.
Alternatives to the Proposed Action: Because the Commission has concluded that there are no significant environmental impacts associated with the proposed action, there is no need to examine alternatives to the proposed action.
-3 Alternative Use of Resources: This action does not involve the use of resources not previously considered in connection with the Final Environmental Statement related to operation of San Onofre Nuclear Generating Station, Unit 1, dated October 1973.
Agencies and Persons Consulted: The NRC staff has reviewed the licensee's request that supports the proposed amendment. The NRC staff 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 amendment.
Based upon the foregoing environmental assessment, the Commission 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 action, see the application for amendment dated April 15, 1988, which is available for public inspection at the Commission's Public Document Room, 1717 H Street, N.W., Washington, D.C.,
and at the General Library, University of California, P.O. Box 19557, Irvine, California 92713.
