Possibilities of using modular high-temperature reactors for the conversion of organic fuels.

Abstract

The possibility of using small modular high-temperature gas-cooled nuclear reactors for the conversion of fuel fossils is considered. The use of high-temperature gas-cooled nuclear reactors as a source of high-potential thermal energy for the conversion of organic fuels is the latest technology that allows processing primary organic raw materials (coal, natural gas, oil, shale) into secondary energy carriers and secondary raw materials for the chemical, metallurgical and other types of industry: hydrogen, converter gas, methanol, reducing gas, carbon black, coke, etc. An important place in the development of high-temperature reactors is occupied by low-power modular reactors, the thermal power of which is in the range of 200...600 MW. Existing and planned modular reactors and their main parameters are given. The possibility of using modular high-temperature reactors for natural gas conversion and coal gasification is justified. Technological schemes of energy technology installations with steam conversion of natural gas and gasification of coal, intended only for ensuring the processes of conversion and gasification, as well as for the production of electrical energy, are given. The method of calculating the energy efficiency of the technological part of the installations and the installation as a whole is described. Quantitative indicators of the energy efficiency of the plants and their parts have been calculated, which lie within 65...80% depending on the technological scheme and the type of technological raw materials and significantly exceed the efficiency of nuclear gas turbine plants at the same temperature of helium at the reactor exit as the considered plants.
