OUR TECHNOLOGY

In 1970, Mitsubishi constructed the first nuclear power plant in Japan using Pressurized Water Reactor (PWR) technology – the Mihama Unit 1 of the Kansai Electric Power Co. For the past four decades, we have been improving PWR plants with our own operational experience as well as through extensive research and development. With this vast knowledge, we are now able to supply PWR plants with unparalleled levels of reliability, safety and output capacity to our utility customers. PWR technology is used by two thirds of the nuclear power plants now operating in the world.

We are now planning our next generation plants, the Tsuruga 3 and Tsuruga 4, using Advanced PWR (APWR) technology. These are scheduled for operation by the Japan Atomic Power Company beginning in 2014. At over 1,500 megawatts output, they will have one of the highest capacities in the world. These units will be capable of producing 30% more total energy than a conventional 4-loop plant. The APWR design will also incorporate a high-performance core that loads MOX fuels and operates over longer cycles.
