All But 3 U.S. Nuclear Plants Performed in Highest Categories in 2015

NRC says all but 3 U.S. nuclear plants performed in highest categories in 2015

The U.S. Nuclear Regulatory Commission (NRC) said all but three of the nation’s nuclear power plants were operating in the two highest performance categories in 2015.

Of the 96 highest-performing reactors, 85 fully met all safety and security performance objectives and were inspected by the NRC using the normal inspection program.

Eleven reactors need to resolve one or two items of low safety significance and now undergo additional inspections and follow-up of corrective actions. The plants are: Clinton in Illinois; Davis-Besse in Ohio, Dresden 2 in Illinois; Duane Arnold in Iowa; Indian Point 3 in New York; Millstone 3 in Connecticut; Prairie Island 2 in Minnesota; River Bend in Louisiana; Sequoyah 1 in Tennessee; and Susquehanna 1 and 2 in Pennsylvania. Duane Arnold. Millstone 3 and Susquehanna 1 and 2 have since resolved their issues and have transitioned to the highest performing level. There were no reactors in the third performance category.

Three reactors were in the fourth performance category. Reactors in this category receive additional inspections and increased NRC management attention to confirm performance issues are being addressed. Arkansas Nuclear One 1 and 2 require increased oversight because of two safety findings of substantial significance. Pilgrim in Massachusetts is in the category because of long-standing issues of low-to-moderate safety significance.

Every six months, each plant either receives a mid-cycle assessment or annual assessment along with an NRC inspection plan. Annual construction oversight assessments for reactors at Vogtle, Summer and Watts Bar 2 are also available.
