The controlled nuclear fusion refers to reaction of synthesis of atomic nuclei, which proceed
in temperature of millions K and energy released in the process could support further reactions
and also might be used as a source of electric energy. The paper comprises concept of future
thermonuclear power plant DEMO based on model AB PPCS. The system of power conversion
of thermal energy into electric energy was accomplished and simulated in program CHEMCAD
6.2. A comparison of different type of power plant was made by calculation of amount of fuel
needed for 1500 MW plant, during one year.
