【《欧洲核子》1985年6月第28页报道】1978年5月,国际原子能机构在维也纳成立了一个工作组,在“国际核燃料循环评价”的范围内研究在把武器级核材料扩散的危险减至最小的情况下和平利用核能的可能性。他们对材料试验堆和研究堆最重要的建议是把高浓铀(80—93%铀-235)燃料改成低浓铀(小于20%铀-235)。由西德核化学冶金公司提供的带状燃料元件的材料试验堆的热功率范围很宽,从1至110MW,因此其燃料元件的铀密度很不
[European Nuclear Report, June 28, 1985, p. 28] In May 1978, the International Atomic Energy Agency established a working group in Vienna to study the dangers of spreading weapons-grade nuclear materials in the context of the “international nuclear fuel cycle evaluation”. Minimize the possibility of peaceful use of nuclear energy. Their most important proposal for material reactors and research reactors is to convert HEU (80-93% U-235) fuel to LEU (less than 20% U-235). The thermal power range of material test reactors for strip fuel elements provided by the West German Nuclear Chemicals and Metallurgy Company is very wide, from 1 to 110 MW, so the uranium density of its fuel elements is very low.
