Abstract: Fuel pellets for use as targets in a device employing thermonuclear fusion by inertial confinement (Laser fusion) are manufactured from high polymer hydrocarbons in which bound hydrogen has been replaced with tritium. The required polymer is prepared by polymerizing monomer(s) which contain carbon and tritium. The hollow pellets are filled with thermonuclear fuel, e.g., a mixture of deuterium-tritium. To improve the sphericity of the pellets and the uniformity of their wall thickness, manufacture of the pellets is contemplated in the near-zero gravity of space.
