Liquid cooling windowless spallation structure

Abstract

The invention provides a liquid cooling windowless spallation structure. The liquid cooling windowless spallation structure comprises an inner drum and an outer drum, wherein a coolant uplink tube and a coolant downlink tube are arranged in the inner drum, the upper portion of the coolant uplink tube is communicated with the upper portion of the coolant downlink tube by virtue of a communication block, a proton track is arranged above the communication block, a driving apparatus is respectively arranged in the coolant uplink tube and the coolant downlink tube, the coolant uplink tube stretches into the outer drum, an upper fixed plate is arranged between the coolant uplink tube and the lower end of the inner drum, a lower fixed plate is arranged between the lower end of the coolant uplink tube and the outer drum, an upper chamber is arranged above the upper fixed plate, a lower chamber is arranged below the lower fixed plate, a heat radiation tube is arranged between the upper fixed plate and the lower fixed plate, the upper chamber is communicated with the lower chamber by virtue of the heat radiation tube, and the lower end of the coolant downlink tube is disposed in the upper chamber. The liquid cooling windowless spallation structure is ingenious in structural design, compact in structure, capable of effectively reducing the size of the liquid cooling windowless spallation structure, and extremely high in popularization value.

Description

technical field [0001] The invention belongs to the technical field of nuclear equipment, and in particular relates to a liquid cooling windowless spallation structure. Background technique [0002] The ADS (Accelerator Driven Sub-critical system) system consists of a proton accelerator, a spallation target and a subcritical reactor. Subcritical reactors cannot complete self-sustaining nuclear reactions due to their fuel selection, and must provide high-energy neutrons from the outside (ie, proton accelerators and spallation targets). The system produces high-energy neutrons by bombarding a heavy metal target with accelerated protons. A large amount of heat will be released during this process, so the spallation target itself needs an independent heat dissipation system to ensure stable operation. [0003] The traditional target design requires external heat exchange system and coolant pump, resulting in a bulky system. Contents of the invention [0004] In view of this...
