Abstract
A shielding container for the transport and storage of irradiated nuclear fuel elements has a cast-metal vessel provided with a radiation-shielding cover whose cylindrical flange is bolted to a shoulder of a seat in the mouth of this vessel and has a thickness of two to four times the thickness of a projection of this cover extending into the space of the vessel receiving the radioactive material. A further cover has a projection extending into the seat and a flange overlying and bolted to the vessel wall. The thickness of the latter flange is twice the thickness of the projection of the further cover and both covers define annular control compartments whereby the sealing effectiveness can be monitored.
