VOGTLE ELECTRIC GENERATING PLANT-UNIT 1 REPLV TO A NOTICE OF VIOLATION NRC INSPECTION REPORTS 50-424:425/93-07 The following is a transcription of the violation as cited in the Notice of Violation (NOV):
"10 CFR 50, Appendix B, Criterion XVI, Corrective Action, requires measures to be established to assure that conditions adverse to quality, such as failures, malfunctions, deficiencies, deviations, defective material and equipment, and nonconformances are promptly identified and corrected.
Contrary to the above, on March 16,1993, a Design Change Package and other associated reference material were not adequately reviewed as part of the corrective action to troubleshoot an illuminated bistable light on the Main Control Board. This resulted in a momentary loss of the only available train of decay heat removal.
This is a Severity Level IV violation (Supplement 1)."
RESPONSE TO VIOLATION (50-424/93-07-05)
Admission or Denial of the Violation This example of the violation occurred as stated in the NOV.
Reason for the Violation This violation was attributed to an inadequate review by Instrumentation and Controls (I&C) personnel of the affected circuitry prior to removing a circuit card for troubleshooting an indication on the trip status light board. An I&C technician and foreman performed these reviews, but they failed to identify all the components afTected by the circuit card. The removal of the circuit card caused residual heat removal system suction isolation valve 1-HV-8701B to close, causing a loss of decay heat removal for approximately 2 minutes.
Corrective Steps Which IInve Been Taken and the Results Achieved
- 1. The IAC technician and foreman have been counseled regarding the importance of adequate reviews.
- 2. Instrumentation and Controls personnel have been briefed regarding this event and the enhanced specific work controls to use when performing this type of work.
Corrective Steps Which Will Be Taken to Avoid Further Violations All corrective actions have been completed, and no further action is warranted at this time.
