NRC raises risk significance for 2013 Arkansas nuclear plant accident
Source: Reuters
The U.S. Nuclear Regulatory Commission (NRC) said on Tuesday that after a series of investigations, it has declared a 2013 incident at an Arkansas nuclear power plant to be of substantial safety significance.
An industrial accident at Entergy Corp's Arkansas Nuclear One plant in Russellville killed one worker and injured eight others on March 31 last year, when a generator fell as it was being moved out of the turbine building.
The accident was initially classified as an unusual event, the lowest of four emergency classifications, because the incident caused a small explosion inside electrical cabinets.
The incident caused unit 2 of the plant to automatically shut down when a reactor coolant pump tripped due to vibrations caused by the heavy component hitting the turbine building floor, damaging electrical cables and equipment, leading to a loss of off-site power.
