摘要： A fuel pellet comprised of an inner cylindrical part provided with a mixture of uranium oxide and plutonium oxide, and an outer annular part integral with the inner part and containing uranium oxide free of plutonium oxide. The fuel pellet is adapted to be inserted into a fuel rod with other such pellets in end-to-end relationship. The pellet is formed by cold pressing the uranium oxide and plutonium oxide in respective inner and outer parts, then sintering the parts to form a monolithic body with the two parts integral with each other.
摘要翻译：燃料颗粒由具有氧化铀和钚氧化物的混合物的内圆柱形部分和与内部成一体的外部环形部分组成并且含有不含钚氧化物的铀氧化物。燃料颗粒适于以端对端的关系插入到具有其它这样的颗粒的燃料棒中。颗粒通过在相应的内部和外部冷压氧化铀和钚氧化物而形成，然后烧结部件以形成具有彼此成一体的两部分的整体。
