NRC Cites Xcel Energy For Prairie Island Problem
MINNEAPOLIS (AP) – The Nuclear Regulatory Commission has cited Xcel Energy for a safety problem involving battery chargers for its Unit 1 reactor at the Prairie Island nuclear plant.
The devices charge batteries that provide backup power for safety equipment. Under certain conditions, the old chargers could lock up. They’ve since been replaced.
NRC staff rated the violation as “white” on a color-coded scale, meaning low to moderate safety significance. Xcel Energy had argued for a “green,” rating, meaning very low significance.
In a final finding issued Wednesday, the NRC stuck with a “white” rating, which means the plant will undergo closer inspections to ensure the problem has been solved. The utility will not be fined.
Xcel Energy has until Sept. 16 to appeal. The company says it’s reviewing the NRC decision.
