testing.- In accordance with the " General Statement-of Policy and Procedure for i
NRCEnforcementActions,"10CFRPart2,AppendixC(1989),theviolationsare l
listed below:
A.
Failure to Provide Sufficient Maintenance Work Instructions River Bend Station Technical Specifications, paragraph 6.8.1.a. requires that procedures for activities identified in Appendix A of Regulatory i
Guide 1.33, Revision 2, February 1978, be established, implemented and L
maintained.
Regulatory Guide 1.33, paragraph 9.c., requires that
-l procedures for the repair or replacement of equipment be prepared prior to c
beginning work.
Administrative procedure ADM-0028, " Maintenance Work Order," Revision 10, L
attachment 2, step 3 requires that the following items be included in the maintenance work order traveler if appropriate. Theseitemsare1) major stepsinthejobplan,2)applicableprocedures,and3) applicable engineering drawings.
Contrary to the above, prompt maintenance work order (NWO) R056226, initiated on Januar 18, 1989, to troubleshoot the "B" recirculation flow control valve (FCV)ycircuity, did not include any references to diagrams, vendor manuals, loop calibration reports, or procedures other than general i
maintenance procedure GMP-0042, " Circuit Testing and Lifted Leads and Jumpers." The troubleshooting activities included replacement of a l
" Modicon unit in panel IH13-P614, B33B-LCIB and gain adjustments on the L
FCV position and velocity controllers. The MWO was subsequently revised on January 20, 1989, to include references to diagrams, loop calibration L
reports, a vendor manual and related procedures to perform additional troubleshooting activities on the "B" recirculation FCV circuity.
This is a Severity Level IV violation (Supplement I) (458/8941-01)
B.
Failure To Perform Post Maintenance Testing Criterion XI of Appendix B to 10 CFR 50 requires that "A test program shall be established to assure that all testing required to demonstrate that structures, systems and components will perform satisfactorily in service is identified and performed in accordance with written test procedures which 90011802f2 900109 PDR ADOCK 05000458 O

-o incorporate the requirements and acceptance limits contained in applicable design documents. The test program shall include, as appropriate, proof tests prior to installation, preoperational tests, and operational tests during nuclear power plant or fuel reprocessing plant operation, of structures, systems, and components. Test procedures shall include provisions for assuring that all prerequisites for the given test have been met, that adequate test instrumentation is available and used, and that the test is performed under suitable environmental conditions. Test results shall be documented and evaluated to assure that test requirements have been satisfied."
Administrative Procedure ADM-0028, " Maintenance Work Order," Revision 10, paragraph 5.12.26, implements these requirements and directs that appropriate post maintenance testing be specified for all components that have been reworked, repaired, replaced or modified.
Contrary to the above, prompt maintenance work order (MW0) R056226 which authorized replacement a " Modicon" card in the "B" recirculation flow control valve circuitry on January 18, 1989, did not require a specific i
In addition, MWO R118514, which authorized replacement of the solenoid valve on the "B" recirculation hydraulic power unit on the same day, did not require specific post maintenance test.
This is a Severity Level IV violation.
