The U.S. Nuclear Regulatory Commission (NRC) said 89 out of 100 operating nuclear power plants met operating standards in 2013.
Of the 89 highest-performing reactors, 80 fully met all safety and security performance objectives. Nine reactors needed to resolve one or two items of low safety significance, and those plants will require additional inspection and attention to follow up corrective actions. Those plants are: Browns Ferry 3 in Alabama; Clinton and LaSalle 2 in Illinois; Fitzpatrick in New York; Grand Gulf 1 in Mississippi; Point Beach 2 in Wisconsin; Prairie Island 2 in Minnesota; Robinson in South Carolina and Turkey Point 3 in Florida. Robinson has resolved their issues since the reporting period ended and has transitioned to the highest performing level.
Nine nuclear reactors have a degraded level of performance, which requires more inspections, senior management attention and oversight focused on the cause of the lowered performance. These plants are Browns Ferry 2, Duane Arnold in Iowa; Monticello in Minnesota; Pilgrim in Massachusetts; Point Beach 1; Sequoyah 1 and 2 and Watts Bar 1 in Tennessee and Susquehanna 2 in Pennsylvania. Both Sequoyah units and Watts Bar 1 have resolved their issues since the reporting and have transitioned to the highest level.
Browns Ferry 1 in Alabama is in the fourth performance category and requires increased oversight because of a high-significance safety finding. Fort Calhoun in Nebraska is under a special NRC oversight program to its extended shutdown and significant performance issues. Though the NRC approved the plant to restart in December, the plant will remain under special oversight until it returns to the regular program.
