Event Report: Massachusetts nuke shuts down due to faulty valve

Today’s  Nuclear Regulatory Commission’s Event Reports included a notice that the Pilgrim nuclear power plant in Massachusetts was in the process of a 24-hour gradual shutdown after the discovery yesterday afternoon that a main feedwater line check valve had become inoperable. Further inspection reveals in leak in a feedwater line.

The plant’s single reactor was at 50 per cent power at the time of the valve failure, following a reduction in power after the station’s single reactor’s High Pressure Coolant Injection system had been declared inoperable. This morning’s Reactor Status report indicates that the unit is currently at 0 per cent output.
