Title:

Tritium Content of a DT Pellet in Inertial Confinement Fusion

Date of publication:

Oct. 1991

Key words:

tritium content, inertial confinement fusion, tritium reduction, DT fusion, fusion reaction, pellet study

Abstract:

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