瑞典核电站的乏燃料将在500m深的基岩坑道系统之中进行处置。瑞典政府于1984年原则上接受了代号为KBS—3的处置方案,其基本设想是将乏燃料包容在多重屏障之中,利用这些屏障在甚长时间内把乏燃料与环境隔离。在置于深部处置库之前,乏燃料组件被包容于带有钢质内衬的圆柱形铜罐之中。在处置坑道的底板上开挖一些专门的处置孔用于放置废物罐,而在每个废物罐周围放置压实的膨润土。深部处置库将分阶段建造。预计2008年将建成处置库的首期工程,其容量约为乏燃料总数的5％～10％。当所有乏燃料放置完毕后,处置库的所有巷道将用膨润土和砂回填、封闭。
Spent fuel for the Swedish nuclear power plant will be disposed of in a 500m deep bedrock system. The Swedish government accepted in principle in 1984 the disposal program KBS-3, which basically conceived of containing spent fuel in multiple barriers and using these barriers to isolate spent fuel from the environment for a long time. The spent fuel assembly was housed in a steel lined cylindrical copper canister prior to placement in the deep repository. Some special disposal holes were excavated on the floor of the disposal tunnel for placement of the waste tank, with compacted bentonite placed around each waste tank. Deep repository will be built in stages. The first phase of the repository is expected to be completed in 2008, with a capacity of about 5% to 10% of the total spent fuel. After all the spent fuel has been placed, all the aisles of the repository will be backfilled with bentonite and sand and closed.
