    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.

    Abstract: A cylindrical elongated furnace for treating material at high temperature in a gaseous atmosphere under high pressure includes a vertical cylindrical pressure chamber for confining gas under pressure and a furnace space surrounded by a cylindrical heater formed of electrical resistor elements and insulation surrounding the furnace space and the heater. The insulation is formed by a cylindrical insulating sheath. The heater is built up of ceramic elements which form a cylinder with annular channels for the electrical resistor elements and supporting insulation surrounding and holding the ceramic elements together, such insulation having a low gas permeability and being formed of several layers of a tight felt impregnated with a hardening component. The leads for the heating elements are flat vertical elements arranged on the outside of the ceramic elements and formed with one or more bights projecting into the annular channels to reduce the free hanging length of the leads.
