Embodiment Construction

[0019] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0020] An embodiment of the present disclosure provides a spallation target material of tungsten alloy particles. The tungsten alloy adopts tungsten-nickel-iron alloy, and tungsten-nickel-iron alloy particles are used as the spallation target material. According to the requirements of the operating conditions of the ADS, pure tungsten metal is too brittle, so this embodiment adopts tungsten alloy to improve the toughness and anti-abrasion performance of the tungsten material. The tungsten content of the tungsten alloy particles is greater than 90% (mass ratio), and the rest is NiFe structure phase. The tungsten alloy of this embodiment has the best comprehensive performance as a spallation target material.

Abstract

The disclosure provides a tungsten alloy particle spallation target material. A tungsten alloy is a tungsten-nickel-iron alloy; and tungsten-nickel-iron alloy particles are of a sphere shape. The tungsten alloy particle spallation target material has the advantages of high neutron yield, high wear resistance, high radiation resistance, resistance to fatigue of a mechanical impact and a thermal shock, excellent thermal and magnetic properties, low machining preparation cost and the like, and is excellent in comprehensive performance.

Description

technical field [0001] The disclosure relates to the technical field of spallation target materials in nuclear energy systems, in particular to a spallation target material of tungsten alloy particles. Background technique [0002] "Accelerator-driven transmutation research device (ADS)" is an advanced clean nuclear energy system, which was approved by the National Development and Reform Commission in December 2015, which will effectively promote the development of ADS in the direction of industrialization in the future. Among them, the heavy metal spallation target is a high-power spallation neutron source, which is a very critical component of the ADS system. Its main function is to generate high-energy neutrons and quickly remove the heat generated by the proton beam bombarding the target material. [0003] There are generally two types of spallation targets: solid metal and liquid metal. In ADS, due to the application of high-power spallation targets and the need to qui...
