The NRC will conduct a supplemental inspection to review whether plant staff understood the cause of the problems, ability to correctly assess and plan for activities involving emergency preparedness, and to assess their ability to identify and resolve problems with appropriate priority. The NRC evaluates a nuclear power p-coded process that classifies regulatory findings as green, white, yellow or red, in order of increasing safety significance. After considering the information regarding this violation at Prairie Island, the NRC staff has characterized the inspection finding as white, or as having a low to moderate safety significance. The company has until April 25 to contest the finding.
