Deuterium-Deuterium Fusion

2H + 2H → 3He + 1n

Visão geral

Two deuterium nuclei fuse to produce helium-3 and a neutron, releasing 3.27 MeV. An alternative D-D reaction produces tritium and a proton. D-D fusion requires higher temperatures than D-T fusion (about 400 million K) but uses only deuterium, which is abundant in seawater.

Exemplo do cotidiano

Deuterium in one gallon of seawater contains enough fusion fuel energy to equal 300 gallons of gasoline.

Importância industrial

A fusão D-D é um objetivo a longo prazo para a energia de fusão porque o deutério é virtualmente ilimitado na água do mar. Contudo, as temperaturas de ignição necessárias são superiores às da fusão D-T, representando um maior desafio tecnológico.
