i NOTICE OF VlOLATION j Entergy Operations. Inc. Docket No. 50-458 ,

River Bend Station License No. NPF-47 1 EA 99-158 iDuring an NRC inspection completed July 10,1999, 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 below:

River Bend Station Technical Specification 3.8.1.b requires that three diesel generators be operable in Modes 1,2 and 3. Technical Specification 1.1 defines OPERABLE as follows: "A system . . . shall Le OPERABLE or have OPERABILITY when it is capable of performing its specified safety function (s) . . ." The emergency diesel generator's safety function is to provide an afternate safety-related electrical power source in response to an event involving the loss of off site power, for the duration cf the event.

10 CFR Part 50, Appendix B, Criterion V requires, in part, that activities affecting quality be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances.

l The River Bend Station " Maintenance Planning Guideline," Revision 6, Section 6.5.9.5  !

states, in part, " Reference all procedures, vendor procedures, and design documents '

required to perform the work instruction and to icturn the . . . system . . . to operational or desired status." )

Contrary to the above:

1. From February 24 to March 25,1999 River Bend Station operated in Mode l without three operable emergency diesel generators. Specifically, the Division i emergency diesel generator was inoperable during this period due to an improperly staked fuel booster pump coupling pin. The coupling pin came loose 55 minutes into a 1-hour sur/eillance run of the diesel on March 24,1999. It was subsequently determined that the diesel had been incapable of performing its '

intended safety function since the fuel booster pump coupling pin was j reassembled during maintenance on February 24,1999.

2. Maintenance Action Item 319116, which provided work instructions for the ,

February 23-24,1999, Division i emergency diesel generator fuel booster pump disassembly and repair, was not appropriate to the circumstances, in that it failed to reference all procedures, vendor procedures, and desigri documents required to perform the work instruction and to return the system to operational status.

- Specifically, the work pbnner did not specify the use of Loctite 680, an adhesive, when assembling the fuel booster pump coupling and did not reference the associated vendor instructions. The " Vendor Manual" contained Cooper-Enterprise Service Information Memo ( SIM 363), Revision 1, dated 12/2/93 which states, in part . . . " Reports have been received from the field that the. . .

fuel booster pump drive couplings have worked loose under certain operation conditions. Failure of this coupling will result in a loss of fuel oil pressure . . .
