PLANT IN-PROCESS COMPUTER OOS FOR MAINTENANCE
"The Beaver Valley Power Station (BVPS) Unit 1 In-Plant Computer (IPC) will be taken out of service for approximately 4 weeks (9/7/10 - 9/30/10) to implement a planned modification. The current IPC is being replaced and a computer outage is required to allow for installation of a new IPC. During this time period the Emergency Response Data System (ERDS) data link to the NRC will not be available at BVPS Unit 1. Other computer based systems not directly associated with the IPC (e.g. Safety Parameter Display System (SPDS), meteorological data) will remain in operation. ERDS parameters will be available to be monitored by control board indications and temporary computer system set up prior to the IPC outage. Compensatory actions have been developed to direct one of the Technical Support Center (TSC) Operations communicators to respond to the control room during a BVPS Unit 1 emergency, should it occur, to facilitate data transfer to the NRC while the ERDS is out of service. Work on replacing the IPC and returning ERDS to service will be ongoing continuously until complete.
"This is an 8-hour reportable event per 10 CFR 50.72(b)(3)(xiii) Major Loss of Assessment Capability. The operation of BVPS Unit 1 and Unit 2 plant systems will not be adversely affected due to this planned action. BVPS Unit 2 ERDS will not be affected by these modifications.
"The NRC Resident Inspector has been notified."

"The Beaver Valley Power Station Unit 1 In-Plant computer has been returned to service. The Emergency Response Data System data link to the NRC is now available.
"The NRC Resident Inspector has been notified."
