摘要

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.
