LOSS OF ASSESSMENT CAPABILITY DUE TO INTEGRATED PLANT COMPUTER PLANNED MAINTENANCE
"On 11/18/2012 at approximately 1130 EST, the Summer Safety Parameter Display System (SPDS) and the Emergency Response Data System (ERDS) will be taken out of service for approximately 12 hours to support a planned maintenance on an inverter that feeds the station's Integrated Plant Computer System (lPCS). During this time frame. ERDS and SPDS will be unavailable. Should the need arise, plant status information will be communicated to the NRC using other available communication systems. SPDS and ERDS are expected to be restored on 11/18/2012 at 1800 EST. This event is reportable under 10 CFR 50.72(b)(3)(xiii).
"The NRC Resident Inspector has been notified."

"On November 18, 2012, at approximately 1730, IPCS was returned to service. Completing this planned maintenance activity restored the VCSNS Safety Parameter Display System and the Emergency Response Data System (ERDS). ERDS was tested this morning, November 19, 2012, by VCSNS and the NRC ERDS Help Desk to verify system operability.
