| Title | Voluntary Notification for an Item of Regulatory Interest |
| Event Description | NUREG 1022 provides event reporting guidelines. The NRC encourages voluntary reporting of items of potential regulatory interest that do not meet any reporting criteria. Dominion Nuclear Connecticut (DNC) has elected to shut down Millstone Power Station Unit 3 to repair a small leak in the residual heat removal system connected to the reactor coolant system. The leak is in the vicinity of a component that was recently identified as not being in full compliance with its design requirements. Although the leak does not appear to be associated with the non-conforming component, it is inaccessible while the unit is operating. Therefore, DNC has elected to shut down the unit, repair the leak, and address the non-conformance.
The NRC Senior Resident Inspector has been notified. |
