[en] It is noted that now in the thermonuclear domain, especially in tokamak application, principle efforts are directed on researches of plasma interaction with a first wall, production of materials with low induced activity, as well as development of technologies are making reactor economically effective. After construction of ITER in the nearest 10 years it is expecting that demonstration reactor DEMO will begin to operate during 25 years period, and to the century middle an industrial thermonuclear power plant will be constructed. Other thermonuclear systems such as lasers, Z-pinches could demonstrating their possibilities in the thermonuclear synthesis within the next few years
