Abstract

Methods are proposed for controlling temporal and space-time pulsed chaos in nuclear reactors where the control actions are implemented as a result of external changes in the neutron multiplication coefficient or introducing external neutron sources. Cases of periodically varying controlling actions and cases where the controlling actions are introduced at the moment the neutron pulses start are examined. The cases of a singly connected regulation system, introducing control at each point of a reactor, and multiconnected systems consisting of several regulators, introducing controlling actions in local regions of the core, are examined. The case where control is introduced in the regions where neutrons bursts start is examined. The proposed methods of control make it possible to excite or suppress pulsed stochastic regimes in reactors and change the regime characteristics purposefully.
