摘要
在1/10的比例模型上完成了反应堆压力容器下降环腔在有安全注入流动时的瞬态温度变化,实验考察了有一回路流动和无一回路流动对瞬态温度变化的影响。实验证明:无一回路流动时,下降环腔内瞬态温度的变化速度和幅值随安全注入流速的增加而增加;有一回路流动时,下降环腔内瞬态温度的变化幅值比同安全注入流速时无一回路流动的变化幅值要小。
An experiment focused on transient temperature in downcomer of RPV during safety injection was performed on a 1/10-scaled model under two conditions: With or without loop flow. It is proved that the progress of transient temperature in downcomer is mainly decided by safety injection flow rate; without loop flow magnitude of temperature drop is larger than that with loop flow.
