7590-01 liNITED STATES NUCLEAR REGULATORY COMMISSION FLORIDA POWER CORPORATION DOCKET NO. 50-302 ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The U.S. Nuclear Regulatory Commission (the Comission) is considering the issuance of-an exemption from the requirements of Appendix 0 to 10 CFC Part 50 to Florida Power Corporation (FPC, the licensee) for the Crystal River Unit 3 Nuclear Generating Station (CR-3) located in Citrus County, Florida.
-ENVIRONMENTAL-ASSESSMENT Identification of Proposed Action:
The proposed exemption would grant a one-time relief from the schedular requirements of 10 CFR Part 50,- Appendix J, paragraphs III.D.2(a) and III.D 3 to perform Type B and C tests within a 2-year interval.
In addition, related changes to the Technical Specifications would be forthcoming. The frequested exemption-would allow the licensee-to defer the Type B and C testing
~
until prior to startup from the next-refueling outage scheduled to begin April 30 1992, an extension of approximately 2 months.-
The licensee's request for exemption nd bases therefor are contained in l-a letter ' dated January 31, 1991, as supplemented May-16, 1991.
The Need for-the Proposed Action:-
The proposed exemption would allcw a one-time relief from performing Type B and C~ tests for_ containment penetrations and containment isolation valves, which would ctherwise require testing between March 1992 and May 1992. This would i~
enable "R-3 to continue normal-plant operation,and therefore prevent an unnecessary premature shutdown of CR-3.

. The purpose of the Type B and C testing is to assure leak-tight integrity of containment isolation valves and penetrations through verification nf acceptable leakage by test.
It also provides assurance that periodic surveillance, maintenance and repairs are made to systems or components penetrating the containment. During the last two Type C tests, the licensee took corrective actions for valve repair to reduce containment isolation valve leakage.
In addition, the licensee has provided a summary of previous leak test results, which showed leakage to be a small fraction of acceptable values.
Environmental Impacts of the proposed Action:
The proposed exemption would allow a one-time relief from the schedular requirements to perform Type B and C tests within a 2-year period. Because of the short extension requested, the previous satisfactory leak test results, and the low likelihood of significant degradation of components involved during the extension period, the preposed exemption will not negatively impact centainment integrity and would not significantly change the risk from any pnstulated accidents. Therefore, post-accident radiological releases will not be significantly greater than previously determined, nor does the proposed exemption otherwise affect radiological plant effluents, or result in any significant occupational exposure.
Likewise, the proposed exemption would not affect nonradiological plant effluents and would have no other environmental impacts. Therefore, the staff concludes that there are no significant radio-logical or nonradiological environmental impacts associated with the proposed exemption.

. Alternatives to the Proposed Action:
Eecause it has been concluded that there are no measurable inpacts associated with the proposed exemption, any alternative to the exemption will have either no environmental impacts or greater environmental impacts.
The principal alternative would be to deny the requested exemption.
Such action would not reduce environmental impacts of CR-3 operations and would result in reduced operational flexibility.
Alternative Use of Resources:
This action does not involve the use of resources not previously considered in the Firal Environmental Statement for CR-3 which was issued in May 1973.
Agencies and Persons Consulted:
The NRC staff has reviewed the licensee's request and did not consult other agencies or persons.
FINDING 0F NO SIGNIFICANT IMPACT The staff has determined not to prepare an environmental impact statement for the proposed exemption.
Based upon the foregoing environmental assessment, we conclude that the proposed action will not have a significant effect on the quality of the human env i rvia,.ent.
For further details with respect to this action, see the application for exemption from 10 CFR Part 50, Appendix J, dated January 31, 1991, as supplemented May 16, 1991, which is available for public inspection at the I
Comission's Public Document Room, 2120 L Street, N.W., Washington, D.C., and at the Coastai Region Library, 8619 W. Crystal Street, Crystal River, Florida 32629.
Dated at Rockville, Maryland this 19th day of September.
