SHIELDING CONTAINER FOR CARRYING FUEL ELEMENT FOR RADIOACTIVE NUCLEAR REACTOR AND METHOD OF FORMING SEALED LAYER IN SAID SHIELDING CONTAINER

摘要

A shielded transport container for irradiated nuclear reactor fuel elements with a container body consisting of spherolytic cast iron and having a cover seat and a cover fitting into the cover seat. At least the cast body (1) of the container body has a surface (2) with open pores (3) and a sealing layer (4). The sealing layer (4) has the texture of a layer (5) which has solidified from a particle melt and whose particles have a diameter which is smaller than that of the open pores (3). It also fills the open pores (3). A process for producing a sealing layer (4) is also indicated. The invention also relates to the particular use of a layer, solidified from a particle melt, as a sealing layer.
