摘　　要：吸收球停堆系统是 10MW高温气冷实验堆 (HTR- 10)的第二停堆系统，本系统利用负压输送过程，将在紧急停堆时进入堆芯反射层孔道内的 B4C小球输送到位于堆顶的贮球罐内，实现正常开堆或反应堆再临界。气力输送技术应用于反应堆工程是一种新的尝试与探索，由此带来了一些新的课题有待进一步的理论和实验研究。本文运用密相输送理论计算了气力输送过程中氦气与 B4C球的气固两相流阻力，并对该系统的最大可信故障进行了理论分析，为该系统的参数设计及设备选型提供了理论依据。： The absorption sphere shutdown system is the second shutdown system of the 10MW High Temperature Gas- cooled Test Reactor (HTR- 10).When the B4C spheres are transported from the reflector columns of the reactor core to the sphere storage pitcher on the reactor pressure shell top by the pneumatic suction conveying process,the reactor can be re- opened safely.The application of pneumatic conveying to the reactor is a new attempt and probe,and some new problems are brought to be studied further by the theory and experiments.The dense- phase conveying theory is used to calculate the pressure lost of the helium- B4C sphere two- phase flow.The most creditable trouble of the system is analyzed by the theory.This paper provide the theoretic foundation for the system parameter design and equipment options.
