Request for a Technical Contact
- Joe, We are looking for someone with experience with electrical containment penetration expertise to help the residents assess an emergent issue.
Wolf Creek recently had 2 over-current events in two pressurizer heater circuits. The attached photos show that the electrical containment penetration was probably overheated and damaged. The penetration seals have a nitrogen supply, and when the supply was isolated, the seal pressure dropped from 55 psi to 40 psi quickly. The licensee declared the containment inoperable and plans an LLRT on the penetration.
The plant has been in a forced outage for over 2 months and is close to starting up, so I think we will have a short time to assess whatever they learn in the next day or so about this problem. Therefore, I am looking (in advance of knowing much) for a knowledgeable person that could help us assess the facts when we get them Could you ask the electrical engineering branch and the safety system containment branch for a name and number to call? OpE might also have something that might be a help.
- Thanks, Neil O'Keefe Chief, Projects Branch B, RIV (o) (817) 200-1241 E)I~ '(b)(6)I 2
