| Title | LICENSEE-IDENTIFIED Violation |
| Description | TS 3.8.4 requires that with one 125 Vdc electrical power subsystem inoperable for reasons other than an inoperable battery charger, the subsystem be restored to an operable state within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />, or if not restored, the plant 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 /> and Mode 4 in 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. Contrary to this, on January 28, 2009, Entergy personnel identified it had remained in Mode 1 with an inoperable 125 Vdc electrical power subsystem for greater than the allowed out-of-service time on two occasions, April 5, 2006 and September 17, 2008. Entergy personnel documented this condition in CRJAF- 2009-00358. The inspectors evaluated this finding using IMC 0609.04, Phase 1 Initial Screening and Characterization of Findings, and determined that the condition was of very low safety significance (Green) because it did not result in the loss of the 125 Vdc electrical power subsystems ability to provide emergency power given actual room temperatures in April 2006 and September 2008 and the plants ability to supply temporary cooling. |
