密度锁内水力平衡特性分析和实验研究

通过简化的理论模型,分析得出在反应堆正常运行工况下,密度锁处于"关闭"状态时必须满足的水力平衡条件,并对影响该条件的主要参数进行分析.结果表明:密度锁内的水力平衡在一定范围内具有自稳定的特性.同时,建立模拟实验同路,对该特性进行实验验证,针对稳态运行过程中主回路内工质流量改变的工况进行实验研究.实验结果表明:当运行参数的变化打破水力平衡后,依靠自稳定特性,能够很快恢复密度锁内的水力平衡,而不会影响密度锁的封闭性和反应堆的正常运行.

Analysis and Experimental Study on Hydraulic Balance Characteristics in Density Lock

Through the simplified theoretical model, the hydraulic balance condition which should be met in the density lock is obtained, when reactor operates normally and density lock is closed. The main parameters influencing this condition are analyzed, and the results show that the hydraulic balance in the density lock is characterized with self-stability in a certain range. Meantime, a simulating experimental loop is built and experimental verification on the self-stability characteristic is done. Moreover, expe...
