10MW高温堆燃料元件输送速度分析与实测结果

Transport speed analysis and measurement for HTR-10 fuel elements

依据燃料元件循环系统设计安全限值，利用气力输送理论，使用反应堆运行工况下参数，对燃料元件输送速度进行了分析，并采用声强分析方法进行了实际输送速度的测量。结果表明，燃料元件通过弯管时最大速度不大于7．36m／s，对垂直钢表面最大撞击速度不大于1．08m／s，均符合设计安全限值的规定。

According to the design safety limits of the fuel elements handling system, the fuel elements transport speed was analyzed with the pneumatic transport theory by using all the real parameters in the reactor operation state, and the transport speed was measured with the sound intensity analysis method. The research results indicate that the maximum speed of the fuel elements passing the bending pipe is no more than 7.36m/s, the maximum vertical impact speed to the steel surface is no more than 1.08m/s, and all the results are in the design safety limits.
