TRITIUM CONTENT OF A DT PELLET IN INERTIAL CONFINEMENT FUSION

A numerical and analytical estimation and a one-dimensional hydrodynamic simulation show that a 30% reduction of the tritium content in a D-T pellet still gives sufficient energy output in a D-T inertial confinement fusion reactor. In other words, the tritium content can be reduced significantly without a significant reduction in the D-T fusion energy output. This new result also means that the tritium inventory can be reduced significantly before and during the reactor operation in the D-T inertial confinement fusion. This result comes from the contribution of a D-D reaction to the D-T reaction.
