ABSTRACT
FEEDBACK CONTROL SYSTEM OPTIMIZATION OF THE PRIMARY PUMP FOR PIUS REACTOR. Thermal hydraulic experiments using a small scale thermal-hydraulic test loop have been performed for the Process Inherent Ultimate Safety (PIUS) reactor simulation to develop the pump speed feedback control system. Three feedback control systems based on the measurement of flow rate, differential pressure, and fluid temperature distribution in the lower density lock have been proposed and confirmed by a series of experiments that is carried out in JAERI Japan. Each of the feedback control systems had been verified in the simulation experiment such as a start up simulation test. The automatic pump speed control based on the fluid temperature at the lower density lock was quite effective and optimal to maintain the stratified interface between hot primary water and cool poison water for stable operation of the PIUS reactor.
