概述了一种新型包覆燃料颗粒--氮化铀三结构各向同性燃料的概念开发、设计、制造和早期辐照试验。这种燃料颗粒提供的铀密度明显高于历史上的涂层燃料颗粒，可能更适合于一系列先进的反应堆应用。在审查了设计过程之后，讨论了涉及这种燃料形式的生产的步骤。这种燃料颗粒的低燃耗辐照数据现已可用，表明迄今为止，根据最初的设计预期，性能指标已得到满足。
A summary of activities around concept development, design, manufacturing, and early irradiation testing of a novel coated fuel particle, uranium nitride tristructural-isotropic fuel is provided. This fuel particle offers significantly higher uranium density over historic manifestations of coated fuel particles and may be more optimal for a range of advanced reactor applications. After reviewing the design process, steps involving production of this fuel form are discussed. Low burnup irradiation data on this fuel particle are now available, indicating that performance metrics have been met to date based on the original design expectations.
