摘　　要：由于高温气冷堆核电站示范工程(HTR-PM)的燃料元件、运行方式、换料方式等与压水堆核电站差别很大,其核材料管制方案不同于传统压水堆;为此在分析HTR-PM球形燃料元件特点、贮存、平衡区设置、盘存、衡算等的基础上,提出了球床式高温气冷堆核材料管制方案,并进一步提出了该类新型核设施的核材料管制技术优化构想。High temperature gas-cooled reactor(HTR-PM)nuclear power plant demonstration project is a representative reactor type in the fourth generation nuclear power system.It uses a large number of spherical coated particle fuel elements.The fuel elements,operation mode and refueling mode of HTR-PM are quite different from those of PWR.These characteristics determine that the nuclear material control scheme is different from the traditional PWR.In this paper,the characteristics of HTR-PM spherical fuel elements,storage,balance area setting,inventory and calculation are introduced.On this basis,the nuclear material control scheme of HTR-PM ball bed type high temperature gas cooled reactor is proposed,and the optimization idea of nuclear material control technology for this new type of nuclear facility is further proposed.
