为使浓缩钚达到武器级水平,美国能源部正加速发展激光技术。今年,能源部将花费1850万美元用于激光浓缩钚研究,明年可望花费2580万美元。这是先进同位素分离部主任哈伯曼(NortonHaberman)透露的。开始于1975年的这项保密研究计划,每年大约花费500万美元。这项工作正在洛斯·阿拉莫斯国家实验室和劳伦斯·利弗莫尔实验室进行,这两个实验室在激光浓缩铀较公开的研究方面领先。其目的是提纯钚,去除高放射性(和无用的同位索 Pu-240和 Pu-241,只留下极易裂变的 Pu-239——原子弹材料)。据能源部估计,如果这项技术研究成功,最早的浓缩钚工厂将在1990年运转。关于激光法的应用,
In order to achieve a weapons-grade level of enrichment, the US Department of Energy is accelerating the development of laser technology. This year, the Department of Energy will spend 18.5 million US dollars for laser enrichment research, and it is expected to spend 25.8 million US dollars next year. This was revealed by Norton Haberman, director of the Advanced Isotope Separation Department. This confidential research program, which began in 1975, costs about $5 million a year. This work is being performed at the Los Alamos National Laboratory and the Lawrence Livermore Laboratory, which lead the public in laser-enriched uranium. Its purpose is to purify thorium and remove highly radioactive (and useless Pu-240 and Pu-241, leaving only fissile Pu-239 - atomic bomb material). According to the Ministry of Energy’s estimation, if this technology is successfully researched, the earliest concentration plant will operate in 1990. About the application of laser method,
