R&D to clarify the specifications of the in-vessel transporter (IVT) design in detail has been performed with feasible outputs, i.e., the demonstration of final installation to within 0.5 mm between the blanket module and two keys by using torque control to avoid any jamming as a result of excessive loading during the module installation process. In addition, rail connection and cable handling in the transfer cask, which are critical issues for IVT system, have been demonstrated from view points of the accurate connection of rail joint and compact design for cable handling mechanism to handle the cable of 75 mm in diameter.
