| Title | LICENSEE-IDENTIFIED Violation |
| Description | Title 10 CFR 50.47 (b) (5) requires that means have been established for alerting the public within the plume exposure pathway and FEMA-REP-10, Guide for the Evaluation of Alert and Notification Systems for Nuclear Power Plants specifies the design requirements. Contrary to the FEMA approved Alert and Notification System (ANS) design report, an individual siren, designated as S-30, was discovered on April 4, 2007, during a stand under observation of the siren performance testing to not meet design requirements. The siren head failed to rotate while sounding. The licensee noted a similar rotation failure for the siren on July 5, 2006, but did not enter the occurrence in the CAP. In May of 2007 on further investigation, the licensee discovered the rotation had existed since installation in July of 2005 and was a result of factory incorrect wiring. The siren rotation failure was identified in the licensees CAP as AR-01090935. The finding was determined to be of very low safety significance using IMC 0609, Appendix B, Emergency Preparedness Significance Determination Process assessing the licensees current performance in problem identification and resolution |
