摘　　要：为减少放射性废物的产生量,日本六个所后处理厂在建造过程中吸收了乏燃料后处理技术发展的最新成果,对原设计进行了改进,降低了废物产生量,减少了高放废液贮存罐的数目。日本核燃料有限公司和三菱重工长崎研发中心等提出了NOx回收利用工艺,也大大减少了低放射性硝酸钠废物和非放射性硝酸钠废物的产生量。本文叙述了日本六个所后处理厂减少放射性废物产生量方面的情况。The reduction of radioactive waste arising from Rokkasho reprocessing plant is introduced in this paper. Major changes have been made during the construction of the plant to adopt the latest achievement made in the spent fuel reprocessing industry. Change in the design may reduce the volum of radioactive waste generated during the operation of the plant and the number of high-level radioactive liquid waste （HLLW） tanks needed. A variety of technologies, including ones for the management of waste, have been developed for the Rokkasho reprocessing plant. A process for NO. recycling proposed by Japan Nuclear Ltd., and Nagasaki Research and Development Center of Mitsubishi Heavy Industries, Ltd., etc. would greatly reduce the formation of radioactive sodium nitrate waste and non-radioactive waste.
