Corrective Action Completed.
Replaced IRM 16 detector and repaired IRM 17 instrumentation.
Corrective Action Planned.
Evaluate action plan to bring the Nuclear Instrumentation System back to Maintenance Rule (a)(2) status.
Evaluate the adequacy of IV and TDR testing at Oyster Creek to be able to identify this type of failure.
Provide training to engineers and instrument and control maintenance supervisors and managers to enhance testing and evaluation skills.
Previous Similar Occurrences There have been numerous previous detector failures in the industry including past failures at Oyster Creek Nuclear Generating Station.
