The modular high-temperature reactor (HTR-M) is characterized by the use of standardized reactor, heat transfer, and loop components. One or more primary circuit units make up the nuclear steam-generating system (or heat-generating system) of a HTR-M power plant. The core of the helium-cooled HTR-M consists of a randomly packed bed of spherical fuel elements (pebble bed reactor). The characteristic design of the HTR-M core ensures that permissible core temperatures are not exceeded, even if all cooling systems fail. Today, HTR-M power plants can already be applied in the combined generation of electricity, process steam, and/or district heat. In the near future the HTR-M can be used as a heat source for processing plants in the chemical industry, e.g., for methane cracking, coal gasification and similar chemical processes.
