| Abstract: | In order to meet the requirements of the long-time continuous operation, reliability and security of the reactor power control system in nuclear power plant, this paper presents a novel strategy based on the dual redundancies of CPU, power supply and ControlNet field-bus network. Digital modification de-sign is used to replace the traditional analog control system in reactor power to perform reliable control. The system reliability and availability are assessed by calculating and analyzing the main reliability param-eters quantitatively. |
| Keywords: | reactor power regulating redundant control reliability |
