Design and Experiment of Feed-water Control System for CEFR Steam Generator

The feed-water control system of steam generator is an important control system of China Experimental Fast Reactor (CEFR), which needs to be automatically controlled. According to the control requirements of the system, a set of feed-water control scheme is designed, and the control scheme is verified under the on-reactor conditions of CEFR. The results of the on-reactor experiment indicate that this control scheme can maintain the stability of the sodium temperature at the outlet of steam generator under various design conditions, and has the ability to suppress interference from other parameters of the reactor. Through the design and experiment of the feed-water control system of CEFR steam generator, the automatic control of the feed-water control system of CEFR steam generator has been achieved.
