Accident Monitoring System requires that inoperable channels be restored to operable status within 7 days or that a report to the NRC describing plans to restore the channels to operable status he submitted.
The A Train Containment High Range Radiation Area Monitor, RM-6113A, was declared inoperable on September 26,1996, due to spiking. The monitor was removed from service, i
inspected and cleaned, and placed back in service for treeding purposes only. It is suspected that the capacitors for the monitor's power supply are faulty and replacements have been ordered. Troubleshooting to ascertain the exact nature of the failure is on-going. Upon determining the specific failure mechanism, appropriate corrective actions will be taken, the unit will be calibrated, as necessary, tested and returned to service.
The B Train monitor, RM-6113B, continues to function properly and is operable.
