Title | Non-Functional Safety Parameter Display System |
Event Description | At 1804 on 12/03/2006, both Safety Parameter Display System (SPDS) displays in the Beaver Valley Power Station (BVPS) Unit 1 control room were identified as not functioning. Initial evaluation indicated that the system would be returned in less than a day. However, subsequent evaluation determined that vendor assistance would be needed to return the system to operation. The vendor is currently performing maintenance, with the system anticipated to be returned to service today (12/05/2006). Thus, this is being reported as a loss of emergency assessment capability pursuant to 10 CFR 50.72(b)(3)(xiii).
Other BVPS Unit 1 equipment that remain available to adequately address potential emergent events include the Inadequate Core Cooling Monitor (ICCM), the BVPS Unit 1 Plant Computer and the Control Room alarm system. The licensee notified the NRC Resident Inspector.
At 1401 on 12/05/2006, the Safety Parameter Display System (SPDS) was repaired and returned to service at Beaver Valley Power Station (BVPS) Unit 1. The licensee notified the NRC Resident Inspector. Notified R1DO (M. Sykes) |
