Research and development of future high temperature gas cooled reactor

Takada, Shoji; Katanishi, Shoji; Yan, X.; Kunitomi, Kazuhiko 

Design and development of the high temperature gas cooled reactor with a gas turbine electric generation system, the GTHTR300, was carried out by Japan Atomic Energy Research Institute. The GTHTR300 is expected to be a new electric generation system in the early 2010s. Design originalities of the GTHTR300 are a horizontally mounted highly efficient gas turbine system and an ultimately simplified safety system such as no containment building and no active emergency core cooling. These design originalities are proposed based on design and operational experiences in conventional gas turbine systems and Japanese first high temperature gas cooled reactor HTTR so that many R&Ds are not required for the development. Except these original design features, devised core design, fuel design and plant design are adopted to meet design requirements and attain a target cost. This paper describes the unique design features of the GTHTR300 and its deployment plan.
