| description = During a recent Problem Identification and Resolution Inspection, the inspectors reviewed Dominion's conformance with the specifications of ASME Code Section XI and Section III relative to repair of a pressure boundary leak condition that affected the A RCP seal cooler piping, a ASME Class I component. Dominion identified a weld leak affecting the Millstone Unit 2, A RCP seal cooler piping on July 13, 2009, an ASME Class I component. The affected piping is 1.5aD and is part of the reactor coolant pressure boundary. The repair was initiated in accordance with ASME Section XI, which directed Dominion to ASME Section III for weld repair completion and post repair non-destructive examination. On July 17, 2009, Dominion completed the repair welding, and subsequently returned the plant to power on July 25, 2009. Aspects concerning Dominion's performance with regard to this repair activity remain to be reviewed and assessed to ascertain conformance with the applicable ASME Code and NRC regulatory requirements.
