摘要：为了研究快堆粘钠设备的清洗技术，建造了粘钠设备清洗回路。该回路基于水蒸气-氮气清洗方法，主要设备包括低溢液氮贮槽、电热蒸汽发生器、清洗端、废液收集罐、水蒸气冷凝器、水环真空泵、氢分析仪等。通过调试试验，发现了回路存在的间题和采取了相应的改进措施，使清洗回路的功能得到了完善，并确定了清洗回路的操作步骤，为后续的粘钠设备清洗技术的研究提供了保证，同时获得了很多
可直接用于中国实验快堆(CEFR)设备清洗系统的经验。关键词：粘钠设备；水蒸气-氮气清洗；回路调试

Abstract: The water vapor-nitrogen test loop was constructed to study the cleaning technology of sodium contaminated equipment in sodium-cooled fast reactor. The main components of the loop include a liquid nitrogen storage tank, an electric heating steam generator, a cleaning tank, an effluent storage tank, a condenser, a vacuum pump and a hydrogen meter. After a series of commissioning tests, some problems were found and the corresponding improvement measures were taken. The experiment procedure of the loop which was confirmed by the commissioning tests provided a guarantee for the following studies on the cleaning technology of sodium contaminated equipment.A number of experiences gained from the commissioning tests could be used in the equipment eleaning system of China Experimental Fast Reactor (CEFR).
