Abstract:
Reactor protection system is a key part of instrument and control system in nuclear power plants. In order to detect the fault of the protection system equipment, validate the availability and assure the nuclear power plant safety, the periodic fault detection shall be applied. This paper introduces the fault detection design, scope and function of the reactor protection system in Hainan Changjiang nuclear power plant based on Tricon V10 programmable logic controller（PLC）, and also analyzes the characteristics of fault detection.
