3月26日,我院圆满完成我国首座微型中子源反应堆(微堆)低浓化改造,实现满功率运行。这标志着我国已完全掌握微堆低浓化技术,也是中美核安保领域的重大成果,荣获美国能源部“杰出成果奖”。2011年底,中国国家原子能机构批准我院与美国能源部阿贡实验室合作,对我院微堆进行低浓化改造,卸出微堆高浓铀堆芯,装入 March 26, our hospital successfully completed China’s first miniature neutron source reactor (micro-pile) low-concentration transformation, to achieve full power operation. This indicates that China has fully mastered the technology of micro-pile low-concentration and is also a major achievement in the field of nuclear security between China and the United States. It has won the “Outstanding Achievement Award” from the U.S. Department of Energy. At the end of 2011, China’s National Atomic Energy Agency approved our cooperation with the Argonne Laboratory of the U.S. Department of Energy to revamp the micro-heap of our hospital and discharge the micro-HEU core.
