Dry storage casks for spent nuclear fuel. Achieving both safety and economy

With the progress of restarting nuclear power plants that have undergone safety checks, in addition to the continued decommissioning of nuclear power plants that have been operating for many years, a considerable amount of spent nuclear fuel will be generated. Therefore, taking measures to deal with spent nuclear fuel is an important task, and activities toward dry storage using highly-safe transport/storage casks (dry casks) are being promoted. This report presents that Mitsubishi Heavy Industries, Ltd. (MHI), as a comprehensive nuclear power manufacturer, can provide a variety of dry casks according to the fuel type and customer needs, including the dry casks that we have developed and have been approved by the regulatory authorities, in order to contribute to the early realization of safe and secure dry storage.
