摘要
研究了球床堆燃料元件输送的关键子系统——循环系统。针对循环系统的"近等径"球流管路气力输送的动力特性,建立了气动推力表达式以及竖直弯管提升、直管提升等典型管段球流运动模型;在分析系统任务可靠性框图的基础之上,结合管路球流运动分析,建立了循环系统的任务剖面。
The critical system,i.e.,the fuel element cycling system,in pebble bed reactors was analyzed,and the dynamic characteristics of pneumatic transportation of near-diameter sphere was investigated.The expression of pneumatic force on sphere and the equation of sphere velocity in elbow and straight pipes were derived.Mission profile of cycling system was established based on the motion analysis and the reliability block diagram of cycling system.
