【摘要】:中国实验快堆(CEFR)以钠作为冷却剂。事故余热排放系统是CEFR快堆的专设安全设施,在反应堆出现地震、系统供电全部中断、全部蒸汽发生器给水中断的事故工况时,将堆芯余热通过空气冷却器非能动地排放到最终热阱。CEFR事故余热排出系统设计温度为550℃,运行温度最高为516℃,全部为双层管道,管道内运行介质为高温的液态金属钠。通过对事故余热排放系统进行热应变测量和数据分析,掌握系统管道的应力应变情况和监测系统运行状态的应力变化。
[Abstract]:China Experimental Fast reactor (Cefr) uses sodium as the coolant. The accident waste heat discharge system is a special safety facility for the CEFR fast reactor. In the case of an earthquake in the reactor, the power supply of the system is completely interrupted, and the supply water of all steam generators is interrupted. The reactor core waste heat is discharged into the final heat trap. CEFR accident residual heat discharge system inactively through the air cooler. The design temperature is 550 鈩,
