Support for Demonstration of Modular High Temperature Gas Cooled Reactors (HTGRs)
International interest in HTGR technology has been increasing in recent years due to a growing recognition of the potential of HTGR designs to provide high efficiency, cost effective electricity generation appropriate for the conditions in developing countries, and in the longer term to provide a source of high and low-temperature process heat, for nuclear hydrogen and nuclear desalination applications. The inherent safety characteristics of these reactors, buttressed by the robust fuel design, the HTGRs ability to incinerate transuranic elements as well as the experience with thorium as reactor fuel are other reasons for this renewed interest.
Several international research and development as well as power projects are under way in China, France, Japan, Korea (Rep. of), Russia, South Africa and the US, in addition to the European Union and others. Moreover, a prototype reactor, the High Temperature gas-cooled Reactor – Pebble bed Module (HTR-PM) is currently under construction in China with prospects to generate electricity by 2017.
The international exchange of information and co-ordination of HTGR research through the IAEA has helped to establish the foundation for the near future development and deployment of HTGR technology. IAEA gas cooled reactor activities are conducted with the active participation and advice of the Technical Working Group on Gas Cooled Reactors and a coordinated research group on uncertainty analysis in HTGR modeling. Furthermore, the IAEA organizes regular technical meetings on specific topics related to HTGR development and deployment.
Technical Working Group On Gas Cooled Reactors
The Technical Working Group on Gas Cooled Reactors (TWG-GCR) is a continuing working group whose purpose is to advise the IAEA on promoting the exchange of technical information in the field of gas cooled reactors. Created in 1978, the group promotes international cooperation related the development of gas-cooled reactors for electricity and process heat applications. The latter involve high-temperature applications such as hydrogen production and low-temperature applications such as seawater desalination and district heating. The TWG-GCR currently includes participants from the following countries and organizations:
|Indonesia||Japan||Korea (Rep. of)|
|Netherlands||Russian Federation||South Africa|
|United Kingdom||United States of America|
|European Commission||Generation-IV International Forum (GIF)||OECD/NEA|
The role of the IAEA in this regard is to coordinate efforts of Member States to facilitate the development of gas-cooled reactors of various types by taking a systematic approach to the identification and development of key enabling technologies to achieve the highest safety levels, competitive economics and reliability and by addressing common technological issues that could facilitate their deployment.
