NDT REVEALS CIRCUMFERENTIAL INDICATIONS ON RCS HOT LEG DRAIN PIPING
"On April 26, 2009 at approximately 1000 hours during the Beaver Valley Power Station Unit No. 1 (BVPS-1) refueling outage, ultrasonic (UT) examinations were performed on pipe base material per the Materials Reliability Project (MRP) MRP-146 recommendations. The MRP recommendations were to address industry operating experience for similar indications identified by other utilities. Two circumferential UT indications approximately 3/8 inches in length were recorded in the base material adjacent to a socket weld on the horizontal portion of line BV-1 RC-41 which is a two (2) inch drain line that connects to the 'A' Reactor Coolant System (RCS) Hot Leg. The function of this piping is to drain the applicable loop during maintenance periods. The indications are not through wall and there was no evidence of leakage. Similar 2 inch drain lines on the other loops have been inspected satisfactorily.
"The plant is currently shutdown and in Mode 6. The affected RCS loop is not required to be Operable and is currently isolated and drained. Repairs are currently being planned and will be completed prior to
startup.
"This is reportable pursuant to 10 CFR 50.72(b)(3)(ii)(A).
"The NRC Resident Inspector has been notified."

ERDS AND PLANT COMPUTER UNAVAILABLE DURING MAINTENANCE ON COMPUTER ROOM COOLING
"At 1545 on 04/26/2009, the Emergency Response Data System (ERDS) at the Beaver Valley Power Station (BVPS) Unit 1 was removed from service. The ERDS is a direct near real-time electronic data link between the licensee's onsite computer system and the NRC Operations Center that provides for the automated transmission of a limited data set of selected parameters. The ERDS supplements the existing voice transmission over the Emergency Notification System (ENS) by providing the NRC Operations Center with timely and accurate updates of a limited set of parameters from the licensee's installed onsite computer system in the event of an emergency.
"The BVPS Unit 1 plant computer and ERDS was removed from service due to planned maintenance on the River Water cooling to the air conditioning for the computer room. The maintenance is scheduled to be completed in approximately 48 hours. This is being reported pursuant to 10 CFR 50.72(b)(3)(xiii).
"Until the ERDS communication is restored, BVPS Unit 1 would utilize its pre-planned backup information flow path in event of an emergency as provided in Procedure 1/2-EPP-IP-1.4, Attachment G when the ERDS system is not operational.
"The BVPS Unit 2 ERDS is not affected and remains operational.
"The NRC Resident has been notified."

"As of 1320 on 04/29/2009, the BVPS Unit 1 plant computer and the data communication link to the Emergency Response Data System (ERDS) were returned to service.
"The site NRC Resident Inspector has been notified."
