Pellet fueling of helium-3 enclosed in Li and Be shells

The proposed design of a fuel pellet containing liquid /sup 3/He enclosed in a spherical Be shell of 300 mu m thickness and overcoated with D/sub 2/ solid is described. The pellet appears to be adequate for fueling large-size d//sup 3/He tokamaks. Smaller pellets of this design could be used for near-term experiments. The pellet fabrication should be simple and the components are nonradioactive.<>
