NRC Information Notice 2007-11: Recent Operator Performance Issues at Nuclear Power Plants   [open pdf - 40KB]

The purpose of this U.S. Nuclear Regulatory Commission (NRC) information notice (IN) is "to alert addressees of recent operator performance issues such as examples of misalignments that rendered plant safety systems inoperable and instances in which operators did not control reactivity as specified in plant procedures. The NRC expects that recipients will review the information for applicability to their facilities and consider actions, as appropriate, to prevent similar occurrences. However, suggestions contained in this IN are not NRC requirements; therefore, no specific action or written response to this notice is required."
