Automatic Start-up System of Nuclear Reactor Based on Sequence Control Technology

A conceptive design of an automatic start-up system based on the sequence control for the nuclear reactors is given in this paper,so as to solve the problems during the start-up process,such as the long operation time,low automatic control level and high accident rate.The start-up process and its requirements are analyzed in detail at first.Then,the principle,the architecture,the key technologies of the automatic start-up system of nuclear reactors are designed and discussed.With the designed system,the automatic start-up of the nuclear reactor can be realized,the work load of the operator can be reduced,and the safety and efficiency of the nuclear power plant during its start-up can be improved.
