The Nihon Keizai Shimbun reports that Mitsubishi Heavy Industries (MHI) will commercialize a compact 1,200 MWe advanced pressurized water nuclear reactor (APWR) for sale to US power companies in and after 2011.
In July, Mitsubishi formed a US-based subsidiary - MHI Nuclear Energy Systems - to market a 1,700 MWe reactor in the US. The 1,700 MWe US-APWR is based on the technology of the 1,538 MWe units planned for the Japan Atomic Power Company (Tsuruga 3/4) scheduled to go into operation in 2014 and 2015. Modification to the base technology for the US market include the world's highest level of thermal efficiency (39%), a 20% reduction in plant building volume, and greater economy via increased power generation.
Mitsubishi Heavy hopes its development of the two proprietary reactors will enable it to counter moves by rivals such as General Electric, Toshiba and Hitachi to tap emerging US demand for nuclear power plants.
