3. NATURE OF PHYSICAL PROBLEM SOLVED

The dynamical behaviour of a cooling channel is calculated. Starting from an equilibrium state a  perturbation is introduced into the system. That may be an outer reactivity perturbation or a change in the coolant velocity or in the coolant temperature. The neutron kinetics is treated in the framework of the one-point model. The cooling channel consists of a  cladded and cooled fuel rod. The temperature distribution is taken into account as an array above a mesh of radial zones and axial layers. Heat transfer is considered in radial direction only, the thermodynamical coupling of the different layers is obtained by the  coolant flow. The thermal material parameters are considered to be temperature independent. Reactivity feedback is introduced by means  of reactivity coefficients for fuel, canning, and coolant. Doppler broadening is included. The first cooling cycle can be taken into account by a simple model.

4. METHOD OF SOLUTION

The integration of the point kinetics equations  is done numerically by the P11 scheme. The system of temperature equations with constant heat resistance coefficients is solved by the method of factorization.
