Abstract
A substantially cylindrical canister is oriented in an upright position with its fill hole directed upwardly, and hydraulic cement is loaded into the top of this canister. The canister is then tipped on its side and connected via a swivel coupling to a suction line and to a line through which a radioactive-waste slurry may be fed. The interior of the canister is then evacuated and the canister is rotated about a horizontal axis passing through this swivel coupling. Radioactive waste is then sucked into the canister by the subatomospheric pressure therein and is intimately mixed with cement already inside the canister by inwardly projecting mixing vanes provided inside the canister.
