Abstract
A transport or storage canister for radioactive wastes has an upright one-piece cast iron or steel vessel with an upwardly open mouth adapted to receive a complementary, stepped plug-type cover which is overlain by a safety cover which peripherally overhangs the plug cover and is likewise recessed in the top of the body. Seals are provided between the several steps so that respective gaps or compartments are formed, the compartments communicating with a fitting in the body which enables monitoring or control units to be connected to the compartments to determine whether leakage may have occurred.
