| Title | Temporary Loss of Erds and Spds Due to Planned Maintenance |
| Event Description | The Emergency Plant Information Computer (EPIC) has been shutdown for planned maintenance. The maintenance is expected to last less than six (6) hours. The shutdown of EPIC has caused a loss of the Safety Parameter Display System (SPDS) and Emergency Response Data System (ERDS). This is determined to be a partial, but significant Loss of Emergency Assessment Capability, and is an 8-hr. Non-Emergency 10 CFR 50.72(b)(3)(xiii) required notification.
There are no plant transients or power maneuvers in progress or planned. Actions taken include: performance of the site specific Computer Out-of-service Surveillance (ST-40C) which provides for enhanced Control Room parameter monitoring, additional operating rounds in-plant on a recurring basis, and restriction of scheduled activities that could cause a plant transient. Members of the JAF [James A Fitzpatrick] Emergency Response Organization (ERO) have been briefed on contingencies required during an E-Plan [Emergency Plan] activation. A contingency plan for around the clock maintenance coverage to recover the EPIC if it is not restored as scheduled does exists. The licensee has notified the State, the County, and the NRC Resident Inspector. |
