IMPROVEMENTS IN OR RELATING TO NUCLEAR FUEL MATERIALS

Patent ·
OSTI ID:4841201
A ceramic fuel material consisting of a fissile oxidedispersed in a nonfissile oxide is described which has very low permeability to fission product gases at high temperatures. The nonfissile oxide may be Al/sub 2/O/sub 3/, MgO, BeO, or ZrO/sub 2/ to which an additional oxide, such as SiO/sub 2/. is added to cause the formation of a liquid phase during sintering. The preferable oxide, however, is an aluminous porcelain containing Al/sub 2/O/sub 3/, SiO/sub 2/, MgO, and CaO mixed in the proportions 87: 10:2: 1 by weight and melting at 1500 deg C. Several examples of fuel material prepared using such mixtures are described. (D.L.C.)
