Synopsis:

The subject “Nuclear reactor physics” builds on previously gained knowledge from fundamentals of reactor physics, kinetics, dynamics, thermohydraulics, and thermomechanics. The lectures start with transport theory introduction, trans-port equation formulation, and its utilization in reactor physics. The transport theory requires broad range of nuclear data. The students will learn how continuous and group-wise nuclear data are prepared and how the self-shielding effect is respected in heterogeneous reactors. A special chapter is utilization of perturbation theory. The importance of the adjoint flux for uncertainty and sensitivity calculations in reactor physics will be explained. The final part of lectures is devoted to coupled calculations of neutronics, termohydraulics, and thermomachanics in nuclear reactors.
