| Title | Loss of Emergency Siren Capability Due to Adverse Weather Conditions |
| Event Description | Due to the effects of severe weather related to Hurricane Isabel, local power outages have resulted in an excessive number of sirens within the Salem/Hope Creek 10-mile Emergency Protection Zone (EPZ) being unavailable. At 21:11 on September 18, 2003, 29 offsite sirens were unavailable (22 in Delaware and 7 located in New Jersey). As of 22:11, some sirens have been restored, but there are still 14 unavailable in Delaware and 7 unavailable in New Jersey. It is likely that the functionality of the EPZ sirens will continue to change due to the ongoing severe weather. Sirens will be recovered when power is restored.
This notification is being for both Salem Generating Station and Hope Creek Generating Station pursuant to 10CFR50.72(b)(3)(xiii) as a major loss of emergency assessment, offsite response, or communication capability. Salem Units 1 and 2 are operating at 100% power with all safety related equipment operable. Hope Creek is operating at 94% power with all safety related equipment operable. Power is reduced due to the degraded performance of the non-safety related ventilation system that cools the Reactor Recirculation Pump Motor-Generator Sets. The licensee informed the NRC Resident Inspector.
There are currently 11 unavailable sirens within the Salem/Hope Creek 10-mile Emergency Preparedness Zone (EPZ) (6 in New Jersey and 5 in Delaware). The current availability of sirens no longer constitutes a major loss of emergency assessment capability, offsite response capability, or offsite communication capability pursuant to 10C'FR50.72(b)(3)(xiii). It is anticipated that all sirens will be rendered available as power is restored and storm recovery actions are completed. No further updates to this event report will be provided. The NRC Resident Inspector was informed. |
