氢化锆作为一种新兴的屏蔽、慢化材料,由于ZrHx的氢含量高和密度较低,可作为空间核反应堆的中子慢化材料。俄罗斯已将其作为一种新型高效的屏蔽和慢化材料进行研究;日本已将其应用于MUTSU核动力船压力容器顶部和主屏蔽体之间的空隙处,它可以在220℃运行温度下保持良好的屏蔽效果。在我国研制的热离子核反应堆中子物理模拟实验样机中,固态氢化锆中子慢化剂圆盘是物理样机堆芯必不可少的部件,该材料部件的研制成功与否关系到整个热离子反应堆电源系统的发展。开展氢化锆慢化材料的研制不仅具有较高的研究和应用价值,而且具有较高的经济价值,市场应用前景广阔。中国核动力研究设计院已建立了完整的氢化装置及其检测系统,经过多年的研究实验,积累了大量金属锆及锆合金的氢化工艺的数据和经验,建立了一整套氢化锆工艺控制、成品检验的规程和相关企业标准。
Zirconium hydride, as a new shielding and moderating material, can be used as a neutron moderating material for space nuclear reactors due to its high hydrogen content and low density. Russia has studied it as a new and efficient shielding and moderating material; Japan has applied it to the gap between the top of the MUTSU nuclear-powered vessel pressure vessel and the main shield, which can be maintained at 220 ° C operating temperature Good shielding effect. In China’s thermal neutron nuclear physics simulation experiment prototype, the solid zirconium hydride zirconium neutron moderator core is an essential part of physical prototype core, the development of the material components related to the entire thermionic reactor Power System Development. Development of zirconium hydride slowdown material development not only has a high research and application value, but also has a high economic value, the market has broad application prospects. China Nuclear Power Research and Design Institute has established a complete hydrogenation unit and its detection system. After years of research and experiments, a large number of data and experiences of hydrogenation of metal zirconium and zirconium alloys have been accumulated. A set of zirconium hydride process control and finished products Inspection procedures and related business standards.
