Abstract
The invention is directed to a method for making a glass block containing dioactive fission products in a metal vessel. The method includes the steps of placing the radioactive glass melt in the metal vessel and cooling the same therein. To minimize the formation of fissures in the glass block which is formed, the inner wall surfaces of the metal vessel are coated with a carbon material. The metal vessel is then placed in a thermally-insulating receptacle. The metal vessel is then filled with a radioactive glass melt emanating from a glass melting furnace and, after the filling step, is cooled slowly in the heat insulating receptacle. A container assembly for use in performing the method of the invention is also disclosed.
