In this study, the surge analysis was performed to find out the risk for overflow in a pump station of power plant with different design cases. In case of original design which intake bay length is 36 m, the water level of pump station increases to a maximum of 4.1 m. This result means there is no overflow at the pump station, launching shaft and end shaft, respectively by surging. In case of alternative design, there was no possibility of overflow occurrence since the water level of pump station increased up to 4.4 m. When 4 pumps are tripped, the water level of pump station increases under the height of structure in both original and alternative cases. It was found that the stability of sea water intake system could be secured in spite of the reduction of inlet bay length.
