REACTOR VESSEL HEAD PENETRATION THROUGH WALL LEAK DISCOVERED
"North Anna Unit 2 Reactor Vessel head has an apparent through wall leak on penetration number 63. Engineering decided to treat this penetration as a through-wall leak based on the qualified visual inspection results and liquid penetrant examination of an excavated finding.
"A portion of the weld around penetration 63, approximately 2.75" long, has been excavated to a depth of approximately 1" of weld material. The liquid penetrant exam of this excavation shows there is an indication located in the outside edge of the weld almost the full length of the excavation, and which turns into the weld at the uphill and downhill ends of the excavation.
"Further evaluation will continue. Unit 2 was in a shutdown mode to perform reactor vessel head penetration inspections per NRC Bulletin 2001-01."
The licensee notified the NRC Resident Inspector.
