| Title | Offsite Notification Due to Fish Kill Event |
| Event Description | At 2115 on 7/28/2011, Oyster Creek experienced a fish kill of greater than 100 fish caused by a loss of the thermal dilution plant power. The loss of thermal dilution plant power was based on a faulted breaker in the Oyster Creek/JCP&L substation.
The reported failure was a relay failure inside a 34.5KV substation breaker. Oyster Creek is holding at 53% power until thermal dilution is restored for environmental limitations. The New Jersey Department of Environmental Protection has been notified. The NRC Resident Inspector will be notified. |
