Abstract
1,137,939. Moulding nuclear fuel elements. NUKEM NUKLEAR-CHEMIE UND-METALLURGIE G.m.b.H. 13 Dec., 1966 [18 Dec., 1965], No. 55678/66. Heading B5A. Spherical graphite fuel elements for use in high-temperature nuclear reactors and comprising fuel particles mixed with graphite mass and an amount of binder, are cold pressed in a silicone rubber mould within a steel pressing die, which mould is cylindrical in exterior shape and divided into two symmetrical halves axially or radially and is provided with an ellipsoidal cavity which is deformed to spherical shape during cold pressing at high pressures of up to 7 tons/cm.2 The powder is consolidated to three to five times its original density and occluded air is removed by vent grooves provided in the rubber mould and steel die or by pressing in vacuo. To protect the fuel particles on the surface from damage, the fuel particle containing element is surrounded by a thin, particle free shell of the same graphite as the matrix of the fuel containing core which is initially pre-pressed semi.hydrostatically in rubber moulds at a low pressure of 20/kg./cm.
