CEFR物理启动准备工作正在进行。为了验证CEFR堆芯设计的安全性能,在物理启动阶段需要测量其钠空泡反应性效应。CEFR钠空泡反应性效应实验测量方案是采取两端头密封的实验组件替代测量点位置的燃料组件,通过实验组件密封所形成的空腔来测量钠空泡反应性效应。CEFR堆芯的零功率
CEFR physical start-up preparation is in progress. In order to verify the safety of the CEFR core design, it is necessary to measure its sodium cavitation reactivity effect during the physical start-up phase. The CEFR sodium vacuole reactivity experiment was performed by replacing the fuel assembly at the measurement point with a two-end sealed test assembly and sealing the resulting cavity to measure the sodium void reactivity effect. Zero power of CEFR core
