Abstract

Abstract

Small pressurized water reactor nuclear power plant usually uses compact once-through steam generator, which has dramatically increased steam pressure under load rejection condition. In order to prevent damage to the system equipment caused by excessive steam pressure, based on the establishment of the mathematical model and the control system for the primary and secondary equipment of SPWR, this paper designs the steam dump control system based on pressure mode, temperature-pressure mode and power-pressure mode respectively, and carries out simulation research of SPWR system under load rejection condition. The results show that under load rejection condition, the temperature-pressure mode and power-pressure mode can effectively reduce the steam pressure overshoot compared with the pressure mode.
