Nuclear fuel handling technology

Involves the capability of positioning several hundred tons of heavy materials with about 1 mm precision by fully remote control and the capability of transferring while cooling the fuel. We have a track record of supplying fuel handling equipment for research reactors and development reactors such as Joyo, Fugen and Monju.

Products

  • Fuel handling and storage facilities

  • Fuel handling equipment

Track record

  • Joyo experimental fast reactor

  • Fugen prototype advanced thermal reactor

  • Monju prototype fast breeder reactor

  • High Temperature Engineering Test Reactor (HTTR)

Remote transport of high-level waste

This is a facility that transports high-level waste remotely in a cell after fuel reprocessing, and also features remote maintenance of the equipment. We have a track record of designing and producing equipment that remotely handles and transports highly radioactive substances and equipment that cannot be in close proximity to humans.

Product

  • In-cell equipment (KA facility)

Track record

  • Rokkasho reprocessing

Remote decommissioning of nuclear reactor facilities

We have a track record of conducting actual scale verification tests on a remote reactor body dismantling system aiming at the decommissioning of the reactor of Tokai Power Station. This remote dismantling system enables the reactor vessel to be cut automatically and remotely into large cut pieces weighing about two tons together with the insulation material.

Products

  • Remote dismantling technology test equipment

  • Reactor internal repair facility

Track record

  • Reactor remote system verification testing

  • Tokai Power Station

MOX fuel fabrication

This facility mixes plutonium separated by reprocessing with uranium to produce mixed oxide (MOX) fuel. We are able to provide various facilities related to fuel pellet manufacturing (finishing inspection).
