核临界安全一直是后处理厂重点关注的问题之一。溶解器是其中的关键设备,属于固液多相混合非均匀系统,影响其临界安全的因素很多,其中一个关键参数是温度系数。本实验在非均匀临界安全实验装置上进行了温度实验,测量了高浓硝酸铀酰溶液和燃料元件棒混合堆芯的温度系数。通过实验获得非均匀堆芯的温度系数,可为乏燃料溶
Nuclear criticality has always been one of the key concerns of reprocessing plants. Dissolver is one of the key equipment, belonging to solid-liquid heterogeneous mixed heterogeneous system, many factors affect its critical safety, one of the key parameters is the temperature coefficient. In this experiment, the temperature experiment was carried out on the non-uniform critical safety experimental device, and the temperature coefficient of mixed core of highly concentrated uranyl nitrate solution and fuel element rod was measured. The temperature coefficient of the inhomogeneous core obtained experimentally can be spent fuel
