Abstract
A rotary contactor (10) suitable for liquid/liquid extraction processes in a nuclear fuel reprocessing plant includes a rotor (14) with a contacting chamber (16) defined within it, the chamber being of annular shape with its radial width considerably less than its inner radius. Neutron absorbing material (22) inhibits neutron transmission between different parts of the contactor. Where the rotation axis is upright, liquids may be fed into the contactor via open-topped annular feed channels (30, 32) at the upper surface of the rotor (14). The chamber (16) includes a packing material (42) such as wire mesh, random or structured packing. The contactor also includes an arrangement to control the radial position of the liquid/liquid coalescing interface, or to control the radial position at which one of the liquids is taken off, which may be operated by gas pressure.
