Fuel materials may be protected from their cooling agents by coextruded claddings. The cladding serves to protect the fuel from rapid corrosions prevent the reaction products from entering the cooling systems and help to prevent extensive irradiation-induced growth of the fuel. The cladding is metallurgically bonded to the fuel by coextrusion. Replacement of the plate-type elements with tubular-type elements in the CP-5 reactor allowed an increase of power output from a previous level of 1 megawatt to the present level of 2 megawatts. CP-5 tubular fuel elements consist of three concentric tubes, of which only two contain fuels presently. The principle physical variables in extrusion are pressure, extrusion '' constants'' of the materials, reductions temperatures lubrication, and flowshape. The principles governing the successful coextrusion manufacture of metallic fuel elements are: comparable component stiffnesses, pre-shaping of components, cleanliness of components, streamlined flows and complete lubrication. The method of manufacture and testing of the tubular-type element is described. (auth)
