Arkansas Nuclear One License No.: DPR-51 )

1 During an NRC inspection conducted on August 18 through September 28,1996, two l

violations of NRC requirements were identified. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," NUREG-1600, the violations are listed Selow:

! A. Technical Scecification 6.8.1.a states, in part, that written procedures be i established, implemented, and maintained covering the applicable procedures recommended in Appendix A of Regulatory Guide 1.33, November 1972.

Paragraph H.2.a.1 of Regulatory Guide 1.33, November 1972, states that specific procedures should be written for containment leak rate tests. Procedure 1305.018, Revision 9, " Local Leak Rate Testing - C," is the procedure for testing containment i penetrations. Step 10.2.5 of Procedure 1305.018 states to " vent and drain the i system inside the local leak rate test (LLRT) boundaries in accordance with j radiological work permit requirements." Penetration 14 is the letdown line penetration through containment and the LLRT boundary is between the first outside

< Valve CV-1221 and the two parallel inside Valves CV-1214 and CV-1216.

i Contrary to the above, Penetration 14 was not vented and drained within the LLRT j boundaries, but was vented and drained into the reactor coolant system, which resulted in the introduction of air into the reactor coolant system during reduced inventory and caused a levelindication change.

, This is a Severity Level IV violation (Supplement l} (Violation 50-313/9606-01).

i

, B. Unit 1 Technical Specification 6.8.1.f states, in part, that written procedures shall be ]

established, implemented, and maintained covering fire protection program j

i implementation. l I Appendix 9A.4 of the Unit 1 Safety Analysis Report describes that the ANO Fire Protection Prograrn is controlled and maintained by various plant procedures that i

! include, but are not limited to, maintenance procedures for control of ignition  !

sourCOs.

Step 5.1.1 of Procedure 1003.006, Revision 3, " Control of Ignition Sources," states i that it is the responsibility of the cognizant supervisor for maintenance activities to determine the fire and explosion precautions necessary for the performance of safe work.

Contrary to the above, on September 21,1996, the licensee did not determine the fire and explosion precautions necessary for safe work in that welding was performed on a pressurizer relief valve tailpipe without having sampled and purged the line of hydrogen. As a result, a hydrogen burn occurred.

This is a Severity Level IV violation (Supplement l} (Violation 50-313/9606-02). ,

Pursuant to the provisions of 10 CFR 2.201, Entergy Operations, Inc. is hereby required to submit a written statement or explanation to the U.S. Nuclear Regulatory Commission, -;
