ABSTRACT:
The invention relates to a container (1) for radioactive materials comprising a main hollow body (2) as well as a cover (6) made of at least one first metallic material, the cover being capable of being fixed on the main hollow body by means of sealing means (26) made of a second metallic material poured into a groove (24) defined by the cover and the main hollow body of the container. According to the invention, the cover (6) and the main hollow body (2) are made solid with the sealing means (26) by means of a bonding zone (28), formed by chemical reaction between the first and second metallic materials.The invention likewise concerns a process for closing of such a container (1).
