Title | Licensee-Identified Violation |
Description | Title 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, provides, in part, that procedures shall include appropriate quantitative or qualitative acceptance criteria for determining that important activities have been satisfactorily accomplished. Contrary to this requirement, on February 17, 2009, the licensee failed to verify that the new oil heater thermostat, with the new oil temperature setpoint per Design Change Package 08-13702-21, had appropriate postmaintenance testing to ensure that the heaters would maintain the new required temperature. The postmaintenance test did not have the technicians verify that the heaters would cycle in the correct band. This was identified in the licensees corrective action program as Condition Report 09-2976. This finding is of very low safety significance because the heater control circuit is only an operability factor when the machine is in a standby condition and the safety function was never lost |
