Summary:A highly reliable solid state reactor safety system operated in dynamic mode is described. Direct current signals from detectors for reactor control are converted to pulse signals, which are continuously generated by the circuit until some abnormal condition occurs. The design and construction of several kinds of logic circuits used for reactor control are explained in detail. The fail-safe property of the circuits have been ascertained by tests, and effects due to temperature variation are negligible in a range 10°~50°C. Results of reliability analysis show that the reactor safety system described, with redundant dynamic logic circuits, has the necessary qualities to assure highly reliable and safe operation of reactor plants.
