Abstract

Molded block fuel elements having an isotropic structure useful for gas cooled high temperature power reactors are prepared by first producing an isotropic graphite granulate of high density with a definite porosity from a molding powder and then hot pressing this isotropic granulate together with coated fuel particles at low pressure to isotropic fuel element. The molding powder for making the granulate is made from a mixture of natural graphite and binder resin, synthetic graphite and binder resin or a mixture of both types of graphite powder with binder resin.
