Syllabus of lectures:

1.Dynamics of zero-power reactor (short-term kinetics) (6 lectures): Equations of reactor kinetics, Integral form of kinetic equations, Analytical solution of kinetic equations, Simplified form of kinetic equations, Transfer function of a zero-power reactor, Frequency response of zero-power reactor.

2.Influence of temperature changes on reactor reactivity (1 lecture)

3.Mathematical model of power reactor (3 lectures): Heat transfer in nuclear power reactors, Mathematical model of reactor with temperature feedback, Simplified models of reactor dynamics.

4.Non-stationary heat transfer in the core - decomposed parameters (2 lectures): Analytical solution of non-stationary equation of heat conduction, Analytical solution of non-stationary equation of fuel channel.

Syllabus of tutorials:

The exercises are composed of analytical examples from the lectures, important formulas are derived. There is a brief introduction to numerical methods of solving differential equations. Numerical simulation of some transition processes and their comparison with analytical solution are performed. At least two exercises take the form of measuring the most important dynamic processes at the VR 1 reactor, including comparison with theoretical results.
