    • A method of cycling a nuclear fuel for a fast breeder and a minor actinoids annihilation reactor, which provides a nuclear fuel cycle having technical advantages, such as a safety inherent in a nuclear reactor, a short fuel doubling time and a high uranium resources utilization factor, and economical advantages, comprising the steps of: preparing sphere pack type fuel pins including a nuclear fuel containing uranium-plutonium-mixed nitride fuel and a minor actinoids nitride fuel, and a sodium heat bonding material, installing the fuel pins in a reactor core and burning the same, subjecting the used fuel to fused salt electrolysis, converting the uranium, plutonium and minor actinoids deposited on a cathode into a high-order nitride, recovering the high-order nitride, converting the recovered high-order nitride into mononitride, and manufacturing a nuclear fuel, which contains a uranium-plutonium-mixed nitride fuel and a minor actinoids nitride fuel, from the mononitride.
    • 一种为快速繁殖者和一个小型锕系湮灭反应堆循环核燃料的方法,其提供具有技术优势的核燃料循环,例如核反应堆固有的安全性,短燃料倍增时间和高铀资源利用因子 以及经济的优点,包括以下步骤:制备包括含有铀 - 钚混合氮化物燃料和次要激发态氮化物燃料的核燃料的球形包装型燃料销和钠热粘合材料,将燃料销安装在反应堆堆芯 并对其进行燃烧,使用过的燃料进行熔融盐电解,将沉积在阴极上的铀,钚和次要锕系化为高级氮化物,回收高级氮化物,将回收的高氮氮化物转化成单硝化物, 并且从单硝化物制造含有铀 - 钚混合氮化物燃料和次要的激发态氮化物燃料的核燃料。
