Conceptual design of 1 MW Thorium Molten-Salt Reactor

Nuclear power plays still an important role for supplying world future energy. However, safety, economy, usability and manufacturability have to be greatly improved from present system. Thorium Molten-Salt Reactor (MSR) is one of candidates but existing designs are not suitable for above requirements. The author developed a new conceptual design of small transportable thorium MSR having 1 MWe (2.2 MWth). Thermal property is governing factor of this reactor because it eliminates use of primary piping. Evaluation results of cooling by compressed He, CO2 and N2 higher than 5 m/s from outer surface of reactor vessel indicates availability of 2.2 MWth. (author)
