Abstract

A method of containing spent nuclear fuel or high-level nuclear fuel waste in a resistant material for isolating the fuel or the waste from the environment, includes the provision of an open container and a cover fitting the container opening, with both the container and cover being made of a ceramic material which is given a high density by isostatic hot pressing. The nuclear fuel or the waste is placed in the container, the cover is placed over the opening of the container, and the container with the cover is contained in a gas-tight casing, whereupon the opened container and the cover are joined by isostatic hot pressing into a homogeneous monolithic body within a completely closed space.
