采用水蒸气－氮气、水雾－氮气、真空蒸馏、有机溶剂等清洗方法，对从意大利拆迁的２条钠回路ＥＳＰＲＥＳＳＯ和ＣＥＤＩ的管道和某些设备、部件进行了清洗除钠。管道形状各异、管径不一、长度不等，管径从１．２７ｃｍ到２５．４ｃｍ，长度从０．５ｍ到９．１ｍ。被清洗的设备有电磁泵、冷阱，部件有钠蒸汽捕集器、不锈钢烧结陶瓷过滤器等。清洗除钠过程安全可靠，达到了预期效果。
The pipelines and some equipment and components of two sodium circuits ESPRESSO and CEDI demolished from Italy were cleaned by sodium hydroxide using water vapor-nitrogen, water mist-nitrogen, vacuum distillation and organic solvents. Pipelines vary in shape, diameter and length ranging from 1.27cm to 25.4cm diameter, length from 0.5m to 9.1m. Was cleaned equipment electromagnetic pump, cold trap, sodium vapor trap parts, stainless steel sintered ceramic filters. Cleaning sodium removal process is safe and reliable, reaching the desired results.
