a s APPENDIX A NOTICE Of VIOLAT10N t
Gulf States Utilities Docket: 50-458 River Bend Station Lic se: NPF-47 St. Francisville, Louisiana During an NRC inspection conducted on July 5 through August 15, 1992, violatior,s of NRC requirements were identified.
In accordance with the "Ceneral Statement of Policy and procedure for NRC Enforcement Actions,"
10 CFR Part 2, Appendix C, the violations are listed below:
A.
Technical Specification 6.8.1 requires thct " Written procedures shall be established, implemented, and maintained covering... the applicable procedures recommended in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978."
Regulatory Guide 1.33, Appendix A, states that " maintenance that can affect the performance of safety-related equipment should be properly preplanned and performed in accordance with written procedures, dv omented instructions, or drawings appropriate to the circumstances."
Contrary to the above, on July 29, 1992, maintenance was performed that affected safety-related equipment, without documented instructions, in that mechanics replaced the soft seat rings on the safety relief valve accumulator check valves without a procedure governing the torquing of the seat rings' retaining nut. The failure to properly install the seat rings could affect valve operability.
This is.a Severity Level IV violation.
(458/9226-02) (Supplement 1)
B.
Technical Specification 4.0.5.a requires, in part, that inservice testing of ASME valves be performed in accordance with Section XI of the ASME Boiler and Pressure Vessel Code.
Paragraph IWV-3522(a) of Section XI of the ASME Code states that " Valves that are normally open during plant operation and whose function is to prevent reversed flow shall be tested in a manner that proves that the disk travels to the seat promptly on cessation or reversal of flow."
Contrary to the above, the licensee's testing of the safety relief valve accumulator check valves did not verify that_the disk traveled to the seat promptly in that the licensee tested for seat leakage after disassembly and reassembly of the check valves, but prior to cycling the valve open; therefore, verification of disk travel to the seat was not performed.
This is a Severity Level IV violation.
(458/9226-03) (Supplement 1).
Pursuant to the provisions of 10 CFR Part 2.201, Gulf States Utilities is hereby required to submit a written statement or explanation to the U. S.
