摘要

文章介绍了脉冲加热测量液态铅与 Al2O3 陶瓷和钢在间隙中接触热阻的结果，该间隙是新一代快堆已开发燃料棒中导热液态金属下层的模型。文中介绍了获取和处理实验数据的方法，给出了测量误差的估算结果，并研究了模型间隙中液铅触点的热阻与温度、铅熔化和结晶次数的关系。根据实验结果，对燃料棒中导热液-金属次层的热阻进行了评估。

Investigating the contact thermal resistances of lead in a heat conducting sublayer

The article presents the results of pulse heating measurements for the thermal resistances of contacts of liquid lead with Al₂O₃ ceramics and steel in gaps, modeling a heat conducting liquid-metal sublayer in the developed fuel rods of fast reactors of a new generation. The method of obtaining and processing experimental data is described, the results of estimating the measurement error are presented, and the dependence of thermal resistances of liquid lead contacts in model gaps on temperature and number of melting and crystallization of lead is investigated. Based on the experimental results, the thermal resistance of a heat conducting liquid-metal sublayer in fuel rods is evaluated.
