DPR-68 TENNESSEE VALLEY AUTHORITY BROWNS FERRY NUCLEAR PLANT UNITS I, 2 AND 3 DOCKET NOS. 50-259 50-260 AND 50-296 l.0 INTRODUCTION By letter dated December 21, 1984 the Tennessee Valley Authority (the licensee/TVA) requested amendments to Facility Operating License Nos.
DPR-33, DPR-52 and DPR-68 for the Browns Ferry Nuclear Plant, Units I, 2 and 3.
The amendments would clarify mechanical vacuum pump requirements and correct typographical errors.
- 2. 0 EVALUATION Dr ell Vacuum Breaker Position Indication (Units I and 2 onl The basis for TS 3.?.A and 4.7.A states that the drywell vacuum breaker valve position indicator green light comes on during a closing cycle when the valve position passes through the 30 degree position, and goes off during an opening cycle when the valve passes through the 80 degree position.
The 30-degree figure is a typographical error.
Both figures should be 80 degrees.
These changes correct a typographical error and are acceptable.
Mechanical Vacuum Pum s
The TS specify limiting conditions for operation and surveillance requirements for a "mechanical vacuum pump."
As stated in Final Safety Analysis Report (FSAR) Section 11.4.3, there are multiple vacuum pumps installed.
The amendments change mechanical vacuum pump references from singular to plural.
These changes provide clarification and are acceptable.
3.0 ENVIRONMENTAL CONSIDERATION
S The amendments involve a change in the installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 or a surveillance requirement.
The staff has determined that the amendments involve no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is 8507230510

t 4'
no significant increase in individual or cumulative occupational radiation exposure.
The Commission has previously issued a proposed finding that the amendments involve no significant hazards consideration and there has been no public comment on such finding.
Accordingly, the amendments meet the eligibilitycriteria for categorical exclusion set forth in 10 CFR 51.22(c)(9).
Pursuant to 10 CFR 51.22(b) no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendments.
- 4. 0 CONCLUSION We have concluded, based on the considerations discussed above, that (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed
- manner, and (2) such activities will be conducted in compliance with the Commission's regulations, and the issuance of these amendments will not be inimical to the common defense and security or to the health and safety of the public.
