A control rod ejection accident is initiated by the hypothetical rupture of the control rod drive housing, forcing the rapid ejection of the drive shaft and attached control rod by the resulting hydraulic forces. This accident was analysed for a four-loop Westinghouse pressurized water reactor rated at 3411 MW(thermal) with ARROTTA, a three-dimensional reactor simulator with kinetics abilities developed by the Electric Power Research Institute. This was the first use of ARROTTA that has received a safety evaluation report from the US Nuclear Regulatory Commission (NRC).
