ENCLOSURE 1
NOTICE OF VIOLATION Tennessee Valley Authority Browns Ferry 1, 2, and 3
Docket Nos. 50-259, 50-260, and 50-296 License Nos.
DPR-33, DPR-52, and DPR-68 During the Nuclear Regulatory Commission (NRC) inspection conducted on June 15 - July 15,
- 1991, two violations of NRC requirements were identified.
The first violation involved failure to promptly correct problems with primary containment radiation monitors.
The second violation was for failure to properly restore equipment after releasing a hold notice.
In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions,"
10 CFR Part 2, Appendix C (1991), the violation is listed below:
A.
10 CFR 50, Appendix B, Criterion XVI, Corrective Action, requires that measures be established to assure that conditions adverse to quality such as deficiencies and nonconformances are promptly identified and corrected.
Contrary to the above, this requirement was not met for the following two examples.
The inspector identified these problems associated with the Unit 2 Primary Containment Radiation Monitors on May 24, 1991.
1.
The cause of the alarm condition for control room annunciator 2-XA-55-7C was not promptly corrected.
It was identified that the recorder spikes occurred on a nonalarming radiation monitor.
The blue and green recorder pens were found reversed.
A previous field design change
- notice, FDCN 15208A, to correct the problem had been canceled without correction of the problem.
2.
The units designation and chart recorder paper for recorders 2-RR-90-272CD and 2-RR-90-273CD were in units of MR/HR instead of R/HR.
The high range primary containment radiation recorders are required by Technical Specification Table 3.2.F to have an indication and range of 1-10 exponent 7
R/HR.
The chart paper problem was previously identified by the licensee but the incorrect paper was reinstalled due to an incorrect operator aid cross referencing the chart paper.
This is a Severity Level IV Violation (Supplement I) applicable to Unit Two.
B.
Technical Specification, Section 6.8. 1, Procedures, requires that written procedures be established, implemented and maintained covering those recommended in Appendix A of Regulatory Guide 1.33, Revision 2, February 9108280099 9i080h PDR ADOCK 05000259 G
Tennessee Valley Authority Browns Ferry 1, 2, and 3
Docket Nos. 50-259, 50-260, and 50-296 License Nos.
DPR-33, DPR-52, and DPR-68 1978.
Appendix A of Regulatory Guide 1.33 includes administrative procedures and procedures for controlling repair activities of safety related equipment.
SDSP-14.9, Equipment Clearances, Section 6.6, establishes the requirements for releasing a clearance.
Releasing of a
hold notice requires a
positioning of components and an independent verification of component positioning.
Contrary to the above, this requirement was not meet on July 9,
- 1991, for releasing Hold Notice 0-91-0501 on the 1D diesel generator.
A.25 amp instead of a 15 amp fuse was installed in the trip control power circuit.
This resulted in the output breaker failure to trip from the control panel and motorizing the diesel generator for seven minutes.
This is a Severity Level IV Violation (Supplement I) applicable to all three units.
Pursuant to the provisions of 10 CFR 2.201, Tennessee Valley Authority is t
hereby required to submit a written statement or explanation to the U.S.
Nuclear Regulatory Commission, ATTN:

If an adequate reply is not received in the time specified in this Notice, an order may be issued to show cause why the license should not be modified, suspended, or revoked, or why such other action as may be proper should not be taken.
Where good cause is
- shown, consideration will be given to extending the response time.
