反应堆主回路管系的甩振分析

Pipe Whip Analysis of the Primary System of a Reactor

文中确定了某反应堆主管道发生中破口时流体喷射推力函数;并对管系在此推力函数作用下的甩动进行了理论分析。然后就该响应对反应堆出口接管的影响进行了评价。结果表明:主管道系统在发生中破口时不会产生严重的甩振现象;振动的管道传递给接管的荷载不大。

In this paper,the thrust force function induced when the primary pipe system breaks under the middle break condition is determinated,and theory anlalysis is conducted for the whip of the breaken pipe system by the action of the thrust force.Then,the assesment for the effect of the whip on the nozzle of vessel is presented.It is shown that there is no serious whip of the pipe,and the forces induced by the pipe vibration which are applied on the transition are smaller.
