Experimental and Model Investigations of Dynamics Peculiarities in Periodic Pulsed Reactor IBR-2 Bondarchenko E. A., Pepyolyshev Yu. N., Popov A. K. The results of the investigation of the dynamics of the pulsed reactor of
periodic operation IBR-2 obtained with the aim of substantiation of reliable
and safe operation of the reactor in the course of exploitation are discussed.
An IBR-2 model for the modeling of transitional processes is presented. The
model is constructed on the basis of a module structure using discrete transfer functions of the kinetics blocks, power feedback and automatic regulator with
accounting for nonlinear dependence functions. Good agreement between the
calculated and experimental power transitional processes at reactivity changes
is obtained. As an illustration of the application of the model the data from
the investigation of the influence of the automatic regulator parameters on the transitional processes are presented and recommendations on their optimal
combination are
given. In addition, the results of the use of the model representations to
assess the IBR-2 reactor stability are reported. The parameters and temperature dynamics of an assembly representing a hypothetical combination of two presently operating facilities: a powerful proton accelerator and the IBR-2 active zone
in a subcritical state, are estimated. |
