The simulated tube was developed for analyzing the slitting characteristics of the cross section of the spent fuel cladding tube. Simulated ceramic fuel rod (with mechanical properties similar to the pellets of actual PWR spent fuel) was produced to ensure that the mechanical decladder could slit real PWR spent fuel. We used castable powder pellets that simulate the compressive stress of the real spent UO₂沉淀。用于与类似于实际废燃料的压缩应力模拟粒料生产标准被确定，并且浇注料插入锆锡合金-4管和烧结，以产生模拟的燃料棒。为了研究模拟陶瓷燃料棒的纵切特性，使用机械decladder进行了验证实验。SN - 1687-6075 UR - https://doi.org/10.1155/2020/1905019 DO - 10.1155 /一百九十零万五千○十九分之二千○二十JF - 科学与核技术安装PB - Hindawi出版KW - ER -
