The NRC said the power plant has shown improvement in 10 areas that were inspected, though two less severe violations still need to be addressed. Until they are fixed, the plant will remain in the NRC’s lowest safety grade, the article said.
A malfunctioning emergency cooling valve in Unit 1 led to the “red” finding, the highest safety violation that the NRC gives in its oversight process. The NRC in May 2011 increased oversight at the plant due to the red finding.
In August 2012, NRC issued a “white” finding of low to moderate significance for units 2 and 3 because NRC inspectors said plant operators would not have been able to perform newly implemented procedures for safe plant shutdown and were not adequately trained on the procedures.
