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,主要设备包括低温液氮贮槽、电热蒸汽发生器、清洗罐、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,发现了回路存在的问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。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 cleaning system of China Experimental Fast Reactor （CEFR）.
