Synopsis:

This course is pointed to pass to students the idea about main operating features of nuclear power plants with various types of reactors, about physical coupling amid single components of nuclear power plants and about principles of operating. In the theoretical part, there is briefly described each power plant and its simulator and simulator?s physical background. The main part of this course is dedicated to practising of various tasks (rated output, transiensts, malfunction of components) on simulators. The course takes place in simulators of following power units: VVER-440, VVER-1000, ABWR and CANDU 6. During these exercises the basic physical features of system are always analysed and there are also given reasons of their changes and connections between them.
