 NRC Increases Oversight of Sequoyah 1 Nuclear Unit

The U.S. Nuclear Regulatory Commission (NRC) is increasing oversight of Sequoyah 1 nuclear power plant in Tennessee.
 
The NRC updated its assessment of Unit 1 after its quarterly review of plant performance in October. NRC found that Sequoyah 1 crossed the green-to-white threshold for the unplanned scrams per 7,000 critical hours performance indicator due to one trip in first quarter of 2015 and three trips in the third quarter.
 
The NRC will conduct a supplemental inspection to provide assurance that the causes of the shutdowns are understood, identify the extent of those causes and to ensure that the Tennessee Valley authority’s corrective actions are sufficient.
 
“Overall the Sequoyah plant is operating safety,” said NRC Acting Region II Administrator Len Wert. “However, these shutdowns point to potential performance issues and we want to ensure that TVA addresses them appropriately.”
 
If the plant takes appropriate corrective actions and improves safety performance, the NRC will return to its normal, yet extensive, inspection schedule.
