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 17 July 17,
- 1992, a violation of NRC requirements was identified.
In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions,"
10 CFR Part 2, Appendix C, the violation is listed bel ow:
10 CFR 50 Appendix B, Criterion V, Instructions, Procedures, and Drawings, requires that activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circum-stances and shall be accomplished in accordance with these instructions, procedures, or drawings.
Instructions, procedures, or drawings shall include appropriate quantitative or qualitative acceptance criteria for determining that important activities have been satisfactorily accomplished.
Contrary to the above these requirements were not met in that hydrostatic test pressures used after installation of corrosion monitors in the residual heat removal service water (RHRSW) system were incorrect.
The RHRSW heat exchanger piping components were tested to 185 psi instead of the actual design pressure of 450 psi.
This was discovered by the licensee on June 19,
- 1992, and a
limiting condition for operation was entered that resulted in Loop II Containment Cooling Mode of the RHR System being inoperable.
This condition had existed undetected for 17 days.
During that time other activities associated with redundant equipment resulted in plant conditions that required the plant to be placed in a cold shutdown condition within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
This is an example of a Severity Level IV Violation (Supplement I) applicable to all three units.
