[en] KEPCO is planning to install Anticipated Transient Without Scram(ATWS) Mitigating System for Westinghouse type plants in Korea. In order not to perform plant specific analyses for each plant, the major parameters are compared to those of generic safety analysis results which were performed by Westinghouse owners group. Per the evaluation results, the most conservative results are obtained at Kori unit 2 loss of load/ turbine trip event with ATWS and the peak RCS pressure becomes 3072 psia which is less than the limit of 3200 psig. Therefore, the generic safety analysis results are applicable to Westinghouse type plants in Korea
