Thermal hydraulics of light water reactors general

The objective of the module is to explain and to justify the thermal design of a nuclear reactor and to assess the thermodynamic efficiency of a nuclear reactor (energy conversion).Upon the module completion, the participants will be able to calculate the fuel temperature and define the related safety criteria.
