The creation and operation of high-temperature gas-cooled reactors (HTGR) and gas-turbine nuclear power plants (GNPP) with such reactors made it possible to increase the efficiency of such plants to (46-50) % due to a higher coolant temperature at the reactor outlet of (1000-1100) 0C. At the same time, high-temperature reactors, due to the high-potential heat produced, can be used in non-electric technologies, such as natural gas conversion, coal gasification, chemical, metallurgical, and oil refining industries. To obtain various technological products, isobaric-isothermal reactions are usually used. However, in plants with HTGR and a helium coolant, it is impossible to organize the process of heat supply at a constant temperature of the coolant, and with a slight change in temperature, an excessive increase in the flow rate of the coolant is required. The article substantiates the possibility to increase the efficiency of using the high-potential part of the HTGR heat for the gasification of solid organic fuels by organizing the gasification process at a variable process temperature and a developed heat recovery system in an energy technological installation.
