Description

Purpose: To make reactor-core-flow rate control excellent in stability, rapid response and transient response without using reactor-core-flow rate measuring signals in BWR type reactors. Constitution: The speed of internal pump is controlled during normal operation by the neutron flux controller (which performs proportional integration for the deviation between the reactor power setting value and the neutron flux feedback signal to output pump speed demand signal). Then, the control is carried out by the combination of the reactor-core-flow rate controller and the neutron flux controller only upon occurrence of transient changes in which reactor parameters vary rapidly. (Ikeda, J.)
