Main nuclear power business

We are capable of responding to requests at the research and development stage as well as throughout the entire life cycle of nuclear facilities, from planning and design to manufacturing, installation, maintenance, and decommissioning measures.
We were involved in the construction of the Tokai Power Station, a gas-cooled reactor and the first commercial nuclear power plant in Japan, and have been contributing to each of the research reactors and development reactors, as well as nuclear fuel cycle development with our various technologies.
We will continue to contribute to the development and supply of specialized technologies based on our technical expertise and experience.
