Deuterium-Deuterium Fusion

2H + 2H → 3He + 1n

概述

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.

日常示例

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

工业重要性

D-D聚变是核聚变研究中的长期目标，其燃料氘可从海水中廉价提取，而无需放射性氚，代表着几乎取之不尽的清洁能源潜力。
