【日本《核科学技术》1979年12月报道】烧氘、氚的聚变反应堆,其燃料循环需要从等离子体出口气体中回收未烧掉的氘(D)和氚(T)。回收分为两步:(1)除去氦和其他杂质,(2)分离同位素 D 和T。在同位素分离方法中,低温蒸馏和钯膜级联比较有希望。钯膜级联法利用了普通氢 【Japan Nuclear Science and Technology, December 1979】 Fusion deuterium and tritium fusion reactors whose fuel cycle requires the recovery of unburned deuterium (D) and tritium (T) from the plasma exit gas. Recycling is divided into two steps: (1) removal of helium and other impurities, (2) isolation of isotopes D and T. In isotope separation, cryogenic distillation and palladium membrane cascade are promising. Palladium membrane cascade method uses ordinary hydrogen
