Title	Loss of Capability to Activate Emergency Sirens and Offsite Notification of Same
Event Description	At 1115 EDT on June 9, 2021, during a siren activation test, a loss of the capability to activate the sirens from both Surry local activation sites was identified. The Virginia EOC was participating in the activation test and is aware of the issue and notified the local government authorities in the Surry EPZ of the situation. The NRC Resident has been notified of this issue. The station telecommunications department has been contacted and is aware of the issue. In the event that a radiological emergency should occur at the Surry Power Station, Primary Route Alerting procedures will be put in use by the local jurisdictions. This report is being made in accordance with 10 CFR 50.72(b)(2)(xi) and 10 CFR 50.72(b)(3)(xiii) due to notification of other state and local government agencies of the failure of the Alert & Notification system for Surry. * * PARTIAL RETRACTION ON 6/18/2021 AT 0959 FROM STEPHEN MITCHELL TO THOMAS KENDZIA * * * Surry Power Station Event Notification 55299 is being retracted based upon further evaluation. Surry has three localities (State SAU, James City, and Surry County) with access to the redundant activation trains (primary and backup systems). The actuation tests only one primary and one backup activation panel at two localities, only primary at the State SAU (Situational Awareness Unit) and back up at James City County were tested. Follow-up telecom and vendor investigation revealed that the primary server was functional from James City County that would have actuated all 71 sirens; Consequently, it was concluded that all of the sirens were fully functional from the James City primary system and there was no loss of all sirens as originally reported on 6/9/2021 (EN 55299). EN 55299 also contained a 4-hour Offsite Notification per 10 CFR 50.72(b)(2)(xi) that is unaffected. The NRC Resident Inspector has been notified. Notified R2DO (Miller).
