Reactor power control device

Purpose: To enable the direct control of steam flow rate in reactor core within a limited range of operational amount. Constitution: Time variation of control-rod pattern, reactor core flow rate, reactor power and load setting signal are determined through a reactor-power to flow-rate curve based on a load instruction from a central station. The control rod pattern and the reactor core flow rate are directly controlled in accordance with the changes with time in the control rod pattern and the reactor core flow rate. (J.P.N.)
