METHOD OF CONTROLLING POWER AND AXIAL POWER DISTRIBUTION OF NUCLEAR REACTOR

摘要

A method of controlling power and axial power distribution of a nuclear reactor, the method including controlling power of a nuclear reactor by adjusting a concentration of a boric acid solution by using a proportional integral controller, according to a difference between a coolant reference temperature and a coolant average temperature; and controlling axial power distribution by changing insertion and withdrawal of a full strength control element assembly and a part strength control element assembly, in order to optimize the axial power distribution.
