我院在20世纪80年代初,自主开发、研究、设计、建造了北京原型微堆(1984年)。尔后又设计、建造了商用微堆,国内建有3座,国外建有5座。我院建造的微堆一览表列于表1,这些微堆均是以高浓铀作为燃料。在防止核扩散的国际背景下,2006年12月11—14日,IAEA在维也纳召开微堆低浓化会议,启动了微型反应堆低浓化协调研究项目(CRP)。从此,IAEA每年都专门 In the early 1980s, our institute independently developed, researched, designed and built Beijing prototype microducts (1984). Later, he designed and built a commercial micro-heap, with 3 built in China and 5 built abroad. A list of micro-heaps constructed in our hospital is shown in Table 1. These micro-heaps are based on highly enriched uranium as a fuel. In the international context of preventing nuclear proliferation, from 11 to 14 December 2006, the IAEA convened a meeting on micro-heap and low concentration in Vienna to launch the CRP. Since then, the IAEA has been dedicated every year
