An analysis of heat transitional processes in fuel rods of the fast pulsed reactor by the semi-point dynamical model

A construction of the semi-point dynamical model for analysis of heat transitional processes in fuel rods of fast pulsed reactors and the results of solving of the differential equations with partial derivatives by the finite difference method are presented. Conditions of stability and convergency of the solution in solving differential equations by the finite difference method were also analyzed. Temperature changes of the fuel rods in conditions of rapid changes of the inlet flows and temperatures of the coolant have been gained
