 NRC increases oversight of Palisades nuclear power plant

The U.S. Nuclear Regulatory Commission (NRC) has increased its oversight of the Palisades Nuclear Power Plant in Michigan operated by Entergy (NYSE: ETR).
 
The oversight was increased due to an incident where workers at the plant failed to accurately calculate radiation doses during a project to replace control rod drive houses during a 2014 refueling outage. The doses received by workers were below NRC’s annual radiation limit and are not expected to have any impact on their health.
 
NRC inspectors reviewed the plant’s methodology for calculating doses related to the affected workers and determined that the methodology did not meet NRC requirements. Entergy failed to ensure that radiation dosimeters were placed in the highest exposed location of the body for the activity, which resulted in the inaccurate measurements. Additionally, Entergy did not establish a procedure to ensure proper placement of the dosimeters.
 
Entergy has taken steps to resolve the problem and is developing long-term corrective actions. As a result, the plant will move from Column 1 to Column 2 of the NRC’s action matrix.
