Abstract: Abstract:The potential risk factors of nuclear power unit in conventional method load rejection test were analyzed. Combining with the features of the turbogenerator set used in nuclear power station, the technology of the power measuring method load rejection test for nuclear power unit was demonstrated. The ideas of process control and data analysis of the power measuring method load rejection test for nuclear power unit were put forward. The principle scheme of power measuring method load rejection test for nuclear power unit was designed, and the security of the nuclear power unit load rejection test was improved.
