Benefits of APWR Technology
Mitsubishi Nuclear Energy Systems
Mitsubishi Nuclear Energy Systems, or MNES, provides a range of state-of-the-art replacement components, services, and technologies to U.S. utilities operating pressurized water reactor (PWR) nuclear power plants. These include replacement reactor vessel closure heads, steam generators, and robotic technologies.
The company also offers U.S. utilities the next generation of clean nuclear energy, the US-APWR nuclear power plant. The US-APWR design, specifically engineered for the United States, achieves superior safety, reliability, economy, and compatibility with the environment. Our design grew out of the expertise gained by Mitsubishi's construction of 24 PWRs in Japan.
MNES was established in 2006 by Mitsubishi Heavy Industries (MHI), as the supplier for Mitsubishi nuclear technologies in the United States. From its headquarters in Charlotte, North Carolina, MNES is leading the way for safer and more reliable nuclear energy. MNES seeks to be an “evolutionary” provider of nuclear equipment and services by building on existing technologies rather than to attempt revolutionary advancements.
