Model of Dynamics of the IBR-2M Pulsed Reactor with Temperature and Power Fast Feedback Effects

摘要

A model of dynamics with separate temperature feedback formed by average temperatures of the fuel and the coolant is constructed for the IBR-2M pulsed reactor of periodic operation. It is shown that in this case the feedback reactivity cannot be described only by these components. Therefore, the model was supplemented with the power feedback (dependence of feedback reactivity on power). Discrete transfer functions reflecting the dynamics of pulsed processes in the reactor are used in the model. The feedback parameters are determined experimentally. The model can be used for description of pulse energy variation in a wide dynamic range.
