237Np是α放射体,其半衰期长达2.14×106a。在高放废物中,237Np是产生长期放射毒性的主要核素之一。通过先进的后处理分离技术,将乏燃料中的次锕系元素(Np、Am、Cm)和长寿命裂变产物(例如99Tc)分离回收、最终通过快堆嬗变,将能够大幅降低放射性废物的长期放射毒性和危害。后处理Purex流程中的共去污分离段是分离镎的关键环节,如果能够将乏燃料溶解液中的镎
237Np is an alpha emitter with a half-life of up to 2.14 × 106a. In high-level waste, 237Np is one of the major nuclides that produce long-term radiotoxicity. Through advanced post-treatment separation technology, the minor actinides (Np, Am, Cm) and long-lived fission products (such as 99Tc) in spent fuel are separated and recovered, and finally transmutation through fast reactors will be able to reduce long-term radioactive waste Radiation toxicity and hazards. After-treatment Purex process of total decontamination separation section is a key part of the separation 镎, if the spent fuel solution 镎
