我国核材料是适应我国核工业的需要而逐步发展起来的。五十年代中期,我国开始建立核工业,经过三十多年的努力,已建成了比较完整的核工业和科技体系。其中核燃料循环体系包括铀的地质、采矿、水冶、铀的浓缩、铀冶金、燃料元件制造及其在各种反应堆中照射,乏燃料再处理(提出钚)等 Our nuclear material is gradually adapted to the needs of our country’s nuclear industry. In the mid-1950s, our country started to establish the nuclear industry. After more than 30 years of efforts, a relatively complete nuclear industry and science and technology system has been built. The nuclear fuel cycle system includes geology, mining, hydrometallurgy, enrichment of uranium, uranium metallurgy, manufacture of fuel elements and its irradiation in various reactors, reprocessing of spent fuel (plutonium raised), etc.
