ENCLOSURE 1 NOTICE OF VIOLATION Tennessee Valley Authority Browns Ferry 2
Docket No. 50-260 License No.
DPR-52 During the Nuclear Regulatory Commission (NRC) inspection conducted May 15-June 15,
- 1989, a violation of NRC requirements was identified.
The violation involved failure to comply with Technical Specification requirements to maintain a
minimum number of Residual Heat Removal (RHR) pumps operable.
In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1985), the violation is listed below:
A.
Technical Specification (TS) 3.5.B.9 requires that at least one RHR loop with two pumps or two loops with one pump per loop be operable when the reactor vessel pressure is atmospheric and irradiated fuel is in the reactor vessel.
TS 3.5.D. 1 requires that the equipment area cooler associated with each RHR pump be operable at all times when the pump served by that specific cooler is considered to be operable.
TS 3.5.-D.2 states that when an equipment area cooler is not operable, the pump served by that cooler must be considered inoperable for TS purposes.
Contrary to the
- above, during the period of May 10-25, 1989, the licensee did not meet the TS requirements for at least two operable RHR pumps.
During this period, only RHR Loop I pump "A" was operable, the RHR Loop II pumps ("B" and "D") were inoperable for a scheduled
- outage, and RHR Loop I pump "C" was inoperable due to its associated pump area cooler fan motor rotation being reversed.
II This is a Severity Level IV Violation (Supplement I) and is applicable to Unit 2.
Pursuant to the provisions of 10 CFR 2.201, you are hereby required to submit a
written statement. or explanation to the Nuclear Regulatory Commission, ATTN:
