Deuterium–tritium fusion

In DTF, one deuteron fuses with one tritium, yielding one helium nucleus, a free neutron, and 17.6 MeV, which is derived from about 0.02 AMU.

[6] A 'breeding blanket', made of lithium, is often placed along the walls of fusion reactors so that free neutrons created by DTF react with it to produce more 3H.

[9] Spin-polarized D-T fuel can increase tritium burn efficiency (TBE) by an order of magnitude or more without compromising output.

In a 481 MW ARC-like tokamak with unpolarized 53:47 D-T fuel, the minimum tritium inventory was 0.69 kg.

With advancements in helium divertor pumping efficiency, TBE values of approximately 10%–40% could be achieved using low-tritium-fraction spin-polarized fuel with minimal power loss.
