Embodiment Construction

[0028] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0029] Such as figure 1 , figure 2 As shown in Fig. 1 , a coupling system between an accelerator and a windowless spallation target interface includes an inlet stagnation swirling section, a conical manifold and a pressurized proton beam incident tube. The fluid channel is injected with metal liquid in the inlet stagnation swirling section, and the metal liquid forms a free liquid surface in the fluid channel. The upper part of the free liquid surface in the fluid channel has a pressurized proton beam incident tube, and the pressurized proton beam incident tube passes through the plasma The body air pressure differential device is connected with the vacuum beam tu...

Abstract

The invention discloses a coupling system of an accelerator and a windowless spallation target interface and a liquid level stabilizing method. The coupling system of the accelerator and the windowless spallation target interface comprises an entrance viscous flow spinning section, a cone-shaped collecting pipe and a pressurized proton beam incidence pipe. A through fluid flow channel is formed by the entrance viscous flow spinning section and the cone-shaped collecting pipe. Metal liquid is filled in the entrance viscous flow spinning section. A free liquid level is formed by the metal liquid in the fluid flow channel. The pressurized proton beam incidence pipe is arranged above the free liquid level in the fluid flow channel. The pressurized proton beam incidence pipe is connected with a vacuum beam pipe of the accelerator through a plasma air pressure difference device. A viscous flow spinning fin ring is arranged on the inner wall of the entrance viscous flow spinning section. Stable and vertical flowing is achieved under the condition that vacuum is eliminated.

Description

technical field [0001] The invention relates to an accelerator-driven subcritical system (ADS) in a nuclear facility, in particular to an interface coupling system between an accelerator and a windowless spallation target and a liquid level stabilization method. Background technique [0002] Accelerator-driven subcritical system (ADS) is a new type of nuclear facility that has been researched and constructed internationally in recent years. This facility can provide ultra-high-intensity neutron sources, conduct related nuclear tests, and integrate nuclear waste treatment and nuclear reaction power generation in the A new star of the future nuclear industry. [0003] The ADS system is mainly composed of three parts: the high-current proton accelerator, the spallation target and the subcritical core. The system is a process in which a beam is generated by an intense proton accelerator, and the beam acts on a heavy metal target to cause a nuclear spallation reaction. In this p...
