Beschreibung
Zusammenfassung:	A control system for a nuclear reactor using an algorithm having a time cycle which is short compared with the delayed neutron lifetimes in the reactor. The use of a "stepping drive" or actuator to change an operating parameter by a fixed unit permits changes in the reactivity of the reactor. The short time cycle of the algorithm allows an evaluation of the reactor and actuation of the stepping drive or actuator during a very short period of time. The algorithm includes digital topology permitting the use of non-linear response functions in the determination of the required change in reactivity or period.
