| Title | Intermittent Signal Interference with Emergency Sirens |
| Event Description | At 12:00 on July 13, 2012 it was determined, during a conference call with the Exelon siren vendor, that Oyster Creek emergency planning zone (EPZ) sirens may be unreliable. The unreliability is being caused by an intermittent signal on the frequency used to activate the sirens. Therefore, an 8-hour report is required under 10 CFR 50.72(b)(3)(xiii) due to a potential 'Loss of Emergency Preparedness Capabilities.'
Additionally, Exelon is contacting the Federal Communications Commission (FCC) for troubleshooting and reporting purposes, as well as, the New Jersey Office of Emergency Management (NJ OEM) and the Ocean County Office of Emergency Management to institute compensatory actions. Due to contacting other government agencies a 4-hour report is required per 10 CFR 50.72(b)(2)(xi). Exelon will notify the NRC Operations Center upon full-restoration of the Oyster Creek EPZ siren system. The NRC Resident Inspector has been informed.
As of 2058 EDT on July 14, the licensee has declared that all 42 sirens have been restored to a reliable status. The siren vendor has shifted the activation frequency to avoid the interference. The vendor is still working with the FCC to determine the cause of the interference signal at the original frequency. The licensee has notified the NRC Resident Inspector. R1DO (Doerflein) notified. |
