| event text = The Plant Process computer system (Emergency Response Facility Computer System) will be taken out of service for approximate 3 week period starting October 1, 2007, to implement a planned modification. The current ERFCS is being replaced and a computer outage is required for the installation of the new ERFCS. During this time period Emergency Response Data System (ERDS) and Safety Parameter Display System (SPDS) functions will not be available. However, the Qualified Safety Parameter Display System (QSPDS) will still be operable in the Control Room. This notification is being made to inform the NRC that the ERDS will be unavailable until this modification is complete. The operation of the plant systems will not be affected due to this planned action. ERDS and SPDS parameters will be monitored by control board indications. All contingency actions required by ERFCS-3, ERFCS Maintenance Outage Plant Mode 1, have been taken. Meteorological data to support the Emergency Response Organization (ERO) will be obtained from the local national weather service (if needed) as described in our Radiological Response Plan. A follow up notification, to the NRC will be given once ERDS and SPDS are returned to service. The NRC Resident Inspector has been informed. | | event text = The Plant Process computer system (Emergency Response Facility Computer System) will be taken out of service for approximate 3 week period starting October 1, 2007, to implement a planned modification.
