Nuclear power plant leak prompts white finding by NRC

The Nuclear Regulatory Commission determined that an inspection finding at Entergy’s (NYSE: ETR) 1,176 MW Waterford 3 nuclear power plant in Louisiana is of “white” or low to moderate safety significance. The single-unit plant uses a Combustion Engineering pressurized water reactor that has been in operation since 1985.

NRC said the finding was caused by Entergy’s failure to contain radioactive cooling water from leaking onto work areas, which caused radiation doses to workers during a 2009 refueling outage. The doses were below regulatory limits.

This issue was identified during an NRC inspection in the spring of 2010 to review the effectiveness of radiological control practices during the previous refueling outage.

NRC evaluates performances at plants with a color-coded process that classifies regulatory findings as green, white, yellow, or red, in order of increasing significance.
