Nuclear power generating stations shall maintain their adequate integrity and perform their safety functions during and after design basis events, including the natural disasters such as earthquake, flood, fire, etc. and the postulated accidents, such as loss of coolant accident (LOCA), main steam line break (MSLB) and high energy line break (HELB), which are attended with high temperature, high pressure, high radiation, steam and chemical spray, etc. Equipment qualification is a technology verifying and ensuring that the nuclear equipment can perform their safety functions under the normal, abnormal and accident conditions during the life of nuclear power plants. Equipment qualification is composed of environmental qualification and seismic qualification. Equipment Qualification (EQ) demonstrates, by using a simulation test and/or analysis, that the nuclear equipment is designed and manufactured to properly perform their safety function without any structural deformation and functional failures under the postulated events. This paper introduces equipment qualification procedure to ensure the reliability of nuclear power generating stations safety.
