| Title | Loss of Power to Emergency Operations Facility |
| Event Description | The Emergency Operations Facility (EOF) for Grand Gulf was lost when power was removed from the facility and the EOF diesel generator failed to start. Power had to be removed due to the loss of one phase of the local power supply. Actual plant operations are not affected. The power phase problem and failure of the EOF diesel generator to start are being investigated at this time. The Backup EOF is available if needed.
The licensee notified the NRC Resident Inspector.
As of 09/02/03, power to the Grand Gulf Emergency Operations Facility (EOF) has been restored. The NRC Resident Inspector will be notified. Notified R4DO Charles Marschall. |
