6 APPENDIX A NOTICE OF VIOLATION Gulf States Utilities Docket: 50-458 River Bend Station Operating License: HPF-47 During the NRC inspection conducted from September 18 through October 17, 1989, a violation of NRC requirements was identified. The violation involved failure to follow procedures.
In accordance with the "Ger.eral Statement of Policy and
-Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1989), the violation is listed below:
Failure te Follow Equipment Control and Maintenance Procedures River Bend Station Technical Specification 6.8.1 requires that written procedures be established, implemented, and maintained as recommended in Appendix A of Regulatory Guide 1.33 Revision 2, February 1978.
Regulatory Guide 1.33, Appendix A, paragraph 1.c, requires that administrative procedures be developed for equipment control; and paragraph 9.e, requires general procedures to be developed for control of maintenance, repair, replacement, and modification work.
Three instances were identified in which licensee personnel failed to 4
follow control procedures that had been implemented in accordance with the above requirements.

RiverBendStationOgeratingProcedureADM-0027, Revision 7
" Protective Tagging, paragraph 3.6, states that a clearance requester "may also be by title (i.e., Shif t Supervisor, Control Operator Forer.an, Maintenance Foreman, etc.) as long as they comply with Step F.1 of Attachment 7 of this procedure." Attachment 7, Step F.1 states: " CHECKED AND ACCEPTED - Signature of the person to whom the Clearance is issued, after that person has checked the tags and is satisfied the equipment is safe to work on."
Contrary to the above, on October 4,1989, the inspector observed that a mechanical maintenance foreman directed his maintenance crew to perform work on the penetration valve and main steam isolation I'
valve (MSIV) leakage control system under Maintenance Work Order (MWO) R130425 before indicating that he had checked the tags and was satisfied that the equipment was safe to work on by properly signing the clearance order. After the system had been breached, the foreman improperly executed the clearance order by "back-timing" the i
signature to a time before the maintenance commenced.
2.
River Bend Nuclear Station Procedure ADM-0027, " Protective Tagging,"
paragraph 5.21, requires that " fluid or gas systems that operate with temperatures greater than 200" F or pressures greater than 50 psig should be isolated from the work area by two closed valves in series, with a tell-tale vent or drain open between the isolation valves."

L en in-line air filter to ASCO solenoid air supply valve to l
Damper 1HYP*AOD 11A (under MWO R134876). The PWO was in response to Condition Report 88-0923, which identified the need to provide air
' filtration to safety-related ASCO solenoid valves.to comply with Teble 9.3-4 of the River Bend Updated Safety Analysis Report.
Contrary to the above, the clearance conditions prescribed by procedure ADM-0027 were not established for the maintenance activities performed under NWO R134876. The technician set the isolation conditions of the instrument air supply to the solenoid valve by using tags under Procedure GMP-0042, Attachment 2, " Lifted Lead and Jumper Tag Sheet." The instrument air supply to the ASCO solenoid operated at a pressure of 110 psig.
