Title | Degraded Condition Found in Reactor Coolant System Piping |
Event Description | On Tuesday, March 22, 2016, while performing planned inspections of Unit 1 Reactor Coolant System piping welds, a flaw indication was identified on a 3 inch Charging Line connection to the Reactor Coolant System piping.
NDE [Non-Destructive Evaluation] results showed a change in the flaw since the previous outage inspection and the condition is now determined as not meeting the acceptance criteria specified in ASME Code Section XI. As such, this indication is reportable under 10 CFR 50.72(b)(3)(ii)(A) as a degraded condition. An action plan is being developed. There is no impact on current Unit 1 refueling operations. This condition and the action plan have no impact to the health and safety of the public or employees. The NRC Resident [Inspector] has been notified. |
