The UK Government has committed to building STEP (Spherical Tokamak for Energy Production), a prototype fusion power plant, by 2040, which will use 6Li in its breeder blankets. It has been estimated that a fusion reactor will need 112 kg of 6Li per year per GW of fusion energy. To operate a 2 GW prototype fusion power plant like STEP, approximately 52 tons of isotopically pure 6Li (based on a lithium-lead blanket enriched to 90% 6Li) is likely to be required and this entire quantity of fuel is needed at the point the reactor is commissioned as current fusion reactor designs do not allow for refuelling. Therefore, there is an immediate need to develop efficient and environmentally friendly technologies that can enrich 6Li.

英国政府已承诺在2040年之前建造一个原型聚变发电厂STEP（球形托卡马克用于能源生产），它将在其增殖毯中使用6Li。据估计，一个聚变反应堆每年每兆瓦的聚变能量需要112千克6锂。要运行一个像STEP这样的2吉瓦的原型聚变发电厂，可能需要大约52吨同位素纯6Li（基于富集到90% 6Li的锂铅包层），而且由于目前的聚变反应堆设计不允许换料，在反应堆投入使用时需要这全部数量的燃料。因此，迫切需要开发高效环保的富集6Li的技术。
