A continuous decanter for processing nuclear materials, comprising:
- a first portion including an Archimedean screw and a decanter bowl surrounding a portion of said screw in an operative condition;
- a second portion including drive means connected to said screw for rotating said screw and said decanter bowl about an axis;
- a bearing assembly disposed between said decanter bowl and said drive means;
- and
- first sealing means for forming a seal between said first and second portions when said decanter bowl and said screw are disconnected from said drive means to place the decanter in a non-operative condition so as to prevent the transfer of nuclear contamination between said first and second portions, and said first sealing means allowing fluid communication between said first and second portions in the operative condition.
