Section: claims

1. A method for making fuel particles having metal carbides dispersed in a spherical graphite skeleton comprising: a) adding aqua-mesophase to an alkaline solution to form a first solution,  b) adding a metal salt to said first solution to form a fuel solution,  c) adding said fuel solution to an oil bath to form an emulsion of aqueous spheres in oil and heating and stirring same until said spheres with said metal salts dispersed therein, dry to form solid spheres,  d) filtering said solid spheres out of said oil bath and rinsing and drying same,  e) heating said solid spheres to between 700.degree.-1100.degree. C. for 1-24 hours to carbonize them to amorphous carbon and convert said metal salts to metal oxides,  f) heating said solid spheres to between 2000-3000 C. for 1-8 hours to graphitize said carbon and to convert said metal oxides to metal carbides to form said fuel particles and  g) depositing a carbon-based coating on said fuel particles. 2. The method of claim 1 wherein said metal salt is a fertile or fissle metal salt, which salt has a metal selected from the group consisting of uranium, plutonium and thorium. 3. The method of claim 1 wherein said oil is one selected from the group consisting of coconut oil, vegetable oil, linseed oil, olive oil, and silicone oil. 4. The method of claim 1 wherein before adding said fuel solution to said oil bath, a surfactant is added to said oil bath and stirred therein. 5. The method of claim 4 wherein said surfactant is one selected from the group consisting of PVA, stearic scid, sodium alkyl sulfate, trisodium phosphate and sodium aryl sulfonate. 6. The method of claim 4 wherein sufficient surfactant is added to said oil bath to size the spheres so formed, to between 100-500 microns.
