• A control to bring the state of a reactor system to equilibrium state in time optimum manner is discussed. Non-linear integral equations containing the effects of two kinds of internal feedback and delayed neutrons and also the effect of external control are adopted for the dynamic equations of the system. These equations are reduced to quasilinear (parametric) differential equations, on which the external control applies in the form of a combination of the control reactivity, its rate of change and its acceleration.<BR>Pontryagin's Maximum Principle is applied to a quasilinear system, and several modes of optimum control patterns - nodal, focal, saddle and mixed - are obtained according to the nuclear and thermal properties, the thermal output of the reactor and magnitude of the control. Optimum control is obtained in the form of piecewise constant control referred to a new control parameter which consists of a linear combination of the control reactivity, its rate of change and its acceleration.
