The outer vertical target transition support, an outer transition block and the outer horizontal target transition support are fixed and positioned. A lower cover plate is welded with the transition block main body. An S-shaped cover plate is welded with the outer vertical target transition support. A lower cover plate is welded with the outer horizontal target transition support. A preliminary outer target assembly structure is formed and finish machined.

Abstract: A magnetic confinement fusion reactor includes a host hall, and a host including a Dewar system, a cold shield system, a superconducting magnet system, a vacuum chamber system, a divertor system, a blanket system, a remote operation system, and a maintenance system. The superconducting magnet system includes a central solenoid magnet, a poloidal field magnet, and a toroidal field magnet. The central solenoid magnet is configured to provide necessary volt-seconds. The poloidal field magnet is configured to generate a poloidal magnetic field. The toroidal field magnet is configured to generate a toroidal magnetic field. The plasma is confined by the toroidal magnetic field and the poloidal magnetic field. The vacuum chamber system is provided with a neutron shielding block to protect the superconducting magnets from being damaged by fusion neutrons.

Abstract: A solid target system for the radionuclide preparation, including a cassette, an ejection sub-system, a laser radar positioning sub-system, a cooling sub-system and a control cabinet. The cassette includes a solid target component for the nuclide preparation and a shielding box. The ejection sub-system is configured to eject the cassette to a recovery hole after the nuclide preparation is completed. The laser radar positioning sub-system is arranged above the ejection sub-system, and is electrically connected to the control cabinet. Both sides of the cassette are each provided with the cooling sub-system for cooling down the solid target component. The control cabinet is electrically connected to a direct-current servo motor for controlling an operating state thereof.

Abstract: A divertor heat transfer structure, including a divertor first wall, a hydrophilic film, an outer pipe and an inner pipe. The outer pipe is sleeved on the inner pipe. The divertor first wall is arranged at an end of the outer pipe. The divertor first wall, an inner wall of the outer pipe and an outer wall of the inner pipe enclose a flow chamber. An end of the inner wall facing the divertor first wall is provided with a jet hole, through which the flow chamber is communicated with the inner pipe. The hydrophilic film is arranged on a side of the divertor first wall facing the jet hole, and fixedly connected with the divertor first wall. Through the arrangement of the hydrophilic film at an inner wall of the divertor first wall, a liquid-supply path can be separated from a steam-discharge channel when exposed to heat.

Abstract: A plasma-facing component of a fusion reactor divertor, including an inner target transition support and a dome transition support which are integrated into an inner target-dome transition support. The inner target-dome transition support and an outer horizontal target transition support are each prepared from two materials. The channel connection inside the inner target-dome transition support and the outer horizontal target transition support is realized through an S-shaped flow channel and a collector box. In V-shaped regions of inner and outer targets, a plasma-facing unit is connected to the collector box in the transition support via a bending tube, and is communicated with a coolant flowing through horizontal and vertical targets through an intermediate flow channel in the transition block. A method of preparing the plasma-facing component is further provided.
