Nuclear Fuel Cycling-Related Equipment

The main nuclear products of Hitachi Zosen are spent nuclear fuel transport casks and storage casks, while other products such as nuclear power plant heat exchangers, vessels, and reprocessing plant equipment are auxiliary components. Hitachi Zosen has more than 30 years' experience with casks, as we developed, designed, and fabricated the first domestic transport cask with Japanese licensing in 1978. In 2011, Hitachi Zosen was awarded the N stamp from ASME (the American Society of Mechanical Engineers) for vessels and equipment used at nuclear facilities. Hitachi Zosen is committed to producing nuclear equipment for nuclear power stations.

Casks and canisters

Casks and canisters are containers used for safely transporting and storing spent nuclear power plant fuel.

Casks have many safety features such as heat removal, containing, shielding, and subcriticality with structural strength. We have the ability to design and manufacture casks according to customer needs, and have experience delivering casks on more than 70 occasions to date.

Canisters are used to transport and store concrete casks and other systems. We have delivered more than 400 units to customers in the U.S.
