Apparatus for the continuous treatment of fragmented fuel elements |
摘要 |
Apparatus for treating radioactive comminuted fuel elements with hot nitric acid comprising an endless conveyor which carries the fuel fragments through a U-shaped jacketed tube counter to the flow of acid. The conveyor travels in a conduit which connects to the ends of the U-shaped tube to form a continuous loop. Downstream of the U-shaped tube associated with the conduit is a washing unit, a drying unit, and a discharge unit. Upstream of the U-shaped tube is a feed unit which joins the conduit. A radioactive fission material sensor is located just ahead of the discharge unit and serves to actuate a switch to recycle treated fragments that may still be radioactive. Drive apparatus for the conveyor comprises permanent magnets mounted at spaced intervals on the conveyor and exciter windings surrounding said U-shaped tube to direct forward movement.
