| Title | Licensee-Identified Violation |
| Description | Technical Specification Limiting Condition of Operation (LCO) 3.5.4, Condition B, requires that the RWST be returned to operable status within a completion time of 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />. If the RWST is not returned to operable status within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />, TS LCO 3.5.4, Condition C, requires that the unit be placed in Mode 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in Mode 5 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. Contrary to the above, the licensee made the RWST inoperable by connecting the tank to a non-seismically qualified system for greater than the allowed TS allowed outage time (one hour plus six hours). The licensee performed silica removal using the spent fuel pool purification system and boric acid recovery system prior to each refueling outage. This activity lasted approximately 22 days during each of the last five refueling cycles on each unit. The licensee entered this condition in their CAP as CR 408445. This finding was assessed using IMC 0609, Phase 1 screening worksheet of Attachment 4 and was determined to be of very low safety significance (Green), because the finding represents a qualification deficiency confirmed not to result in the loss of functionality of the RWST. |
