摘要
对SISAK装置萃取分离Sr的条件及Y快速分离装置对Sr-Y的分离条件作了进一步研究,在之前工作的基础上优化了分离流程。根据母核95Sr与94Sr的半衰期差异,采用快速化学分离与衰变分离相结合,从裂变产物中先分离Sr,再进行Sr-Y分离提纯95 Y的方法,在中国原子能科学研究院微型反应堆上成功得到放化纯95 Y,并给出了工艺流程。
The separation condition of strontium from fission products using SISAK system and yttrium from Sr-Y mixture was studied.The separation process was optimized.The method that separates Sr-Y after separation of strontium from fission products was selected,which was based on the half-life difference between 94Sr and 95Sr.Combined the fast chemistry separation and decay characteristic,95Y was separated successfully in the mini-reactor in CIAE.The recommended technological process was given.
