Description | TS 3.1.3, Condition C, requires that control rods that are inoperable for reasons other than being stuck shall be fully inserted and disarmed. TS 3.1.3, Condition E, requires the unit to be in Mode 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> if Condition C cannot be met. On February 11, the 10-51 CRD HCU was declared inoperable for the conduct of maintenance and the TS required actions to fully insert and disarm the CRD were met. Following the completion of maintenance on the HCU, an operator erroneously re-armed the CRD HCU DCVs during the modification of a safety tagging clearance that occurred at approximately 5:30 a.m. on February 12.Over 28 hours3.240741e-4 days <br />0.00778 hours <br />4.62963e-5 weeks <br />1.0654e-5 months <br /> later and in excess of the 12-hour completion time allowed by TS3.1.3, PBAPS personnel discovered the error and disarmed the CRD for Control Rod 10-51. PBAPS documented this issue in the CAP as IR 880318. Since Control Rod 10-51 remained fully inserted and there was no loss of safety function during the period of non-compliance, this issue is of very low (Green) safety significance. The LER associated with the event was documented in Section 4OA3.3. |
