High-Temperature Gas-Cooled Reactors (HTGR) Print

HTGRs are heat sources with extremely high temperature of ~ 1000°C, thus their use allows significant broadening of efficient economic nuclear power application.

In 1970-1980s OKBM developed a number of various purpose and electric power HTGR designs: VG-400 pilot production reactor for process heat and power co-generation in a steam-turbine cycle, VG-400GT reactor plant with direct gas-turbine cycle of power conversion, VGM modular reactor for ~ 900°C process heat and electric power generation, VGM-P nuclear power plant for power supply of a standard oil refinery.

At this period OKBM created research and experimental facilities and a large scope of R&D to validate HTGR designs being developed

International GT-MHR Project

By the beginning of 1990s the achievements relative to gas turbine, electromagnetic bearing, high-effective heat exchange equipment technologies allowed developing an Innovative Project of helium HTGR with gas turbomachine for direct power conversion with ~50% efficiency (Brayton cycle). This concept is the basis of the International GT-MHR Project (Gas-Turbine Modular Helium Reactor). The main project participants are a group of Russian enterprises (OKBM, RRC KI, VNIINM and Others), an American group headed by General Atomics, French Framatome and Japanese Fuji Electric. The Preliminary Design of the reactor plant and GT-MHR prototype NPP was completed in 2001.

"Strategy of Russia Nuclear Power Engineering Development…" provides for construction of GT-MHR prototype NPP and fuel production plant for it at the Siberian Chemical Combine by 2010 and construction and commissioning of the first four-module GT-MHR NPP by 2012-2015.

Technical parameters, safety and economic efficiency of the GT-MHR plants are close to the requirements for promising XXIst century reactor technologies stated by Russian President V.V. Putin at the UN Millenium Summit held in September 2000, and these activities are underway.
