The aim of the subject is to familiarize students with essential machine equipment on different types of nuclear power plants, which are in contact with radioactive isotopes and which can be contaminated during operation and accidents. For example: pipes, valves and fittings, pumps, steam turbines, pressurizer systems, heat exchangers and above all steam generators. Part of the subject is also the description of safety and emergency systems (hydroaccumulators, systems for containment pressure reduction, etc.). Lectures are focused on descriptions of parameters, designs and materials of real devices which are in operation on different nuclear power plants. Students receive knowledge what is important for decommissioning, for communication with colleagues on nuclear power plants and also for practical life.
