7590-01 UNITED STATES NUCLEAR REGULATORY COMMISSION TENN'SSFE VALLEY AUTHORITY c
DOCKET NOS. 50-259, 50-260, 50-296 ENVIRONMENTAL ASSESSMENT AND FINDING OF NO SIGNIFICANT IMPACT The U.S. Nuclear Regulatory Commission (NRC/the Commission) is considering issuance of a temporary exemption from certain requirements of 10 CFR 50.71(e) to the Tennessee Valley Authority (TVA/the licensee), for the Browns Ferry Nuclear Power Plant, Units 1, 2 and 3, located at the licensee's site neue Decatur, Alabama.
ENVIRONMENTAL ASSESSMENT Identification of Proposed Action:
The licensee would be temporarily exempted from meeting the requirement of 10 CFR 50.71(e) to update at least annua'lly the Browns Ferry Updated Final Safety Analyses Report (UFSAR).
The UFSAR for Browns Ferry is currently required to be updated by July 22, 1989.
The licensee's request for temporary exemption would delay transmittal of the 1989 updated UFSAR until the scheduled July 22, 1990 annual update.
The request and the supporting bases for the temporary exemption are contained in the licensee's letter dated May 23, 1989.
The Need for the Proposed Action The temporary exemption is required in order to permit the licensee to complete its UFSAR verification program as well as incorporate the many changes to the plant design and configuration which result from the ongoing restart 8907'o30172 890626 PDR ADOCK 03000259 P

programs and modifications currently being undertaken at Browns Ferry, Unit 2.
J Units 1 and 3 are currently defueled and start-up of units will be after the next scheduled UFSAR update (July 1990).
Environmental Impacts of the Proposed Action:
j The temporary exernption would allow submittal of the updated UFSAR to be 1
delayed for 12 months.
This temporary exemption is administrative and will not affect plant hardware or procedures.
The preposed temporary exemption will not affect plant operation since operations personnel will be provided with up-to-date plant configuration drawings which are utilized in the control room as source material.
Changes which will affect FSAR sections will be placed in special files so that the latest information concerning any part of the UFSAR will te available for review by TVA personnel engaged in screening reviews and safety evaluations.
Accordingly, the temporary exemption will not increase the probability or a
consequences of any reactor accident sequence.
No changes are being made in the types of any effluents that may be released offsite; there is no signifi-cant increase in the allowable individual or cumulative occupational radiation exposure; and the temporary exemption will not otherwise affect any other radiological impact associated with the facility.
Consequently, the Commission concludes that there are no significant radiological impacts associated with the proposed temporary exemption.
With regard to potential non-radiological impacts, the proposed temporary exemption does not affect non-radiological plant effluents and has no other environmental impact.
Therefore, the Connission concludes that there are no significant noil-radiological environmental impacts associated with the proposed temporary exemption.
3 Alternatives to the Proposed The Commission has concluded that there is no significant environmental impact associated with the proposed temporary exemption.
Therefore, any alternatives to the temporary exemption will have either equal or greater environmental impact and need not be evaluated.
The principal alternative would be to deny the requested temporary exemption.
Such action would not reduce the environmental impact of the Browns i
Ferry Nuclear Plant, Units 1, 2 and 3, operations.
Alternative Use of Resources These actions associated with the granting of the proposed temporary exemption as detailed above do not involve the use of resources not previously l
considered in connection with the Final Environmental Statement (construction i
f permit and operating license) (FES) for the Browns Ferry Nuclear Plant, Units l
1, 2 and 3, dated September 1, 1972.
Agencies and Persons Consulted The NRC staff reviewed the licensee's submittal that supports the proposed temporary exemption discussed above and did not consult other agencies or persons.
FINDING OF N0 SIGNIFICANT IMPACT The Commission 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 environment.
