Deuterium-Tritium Fusion

2H + 3H → 4He + 1n

概述

Deuterium and tritium fuse at temperatures exceeding 100 million degrees to form helium-4 and a neutron, releasing 17.6 MeV of energy. This is the most feasible fusion reaction for power generation because it has the lowest ignition temperature and highest cross-section. The neutron carries 80% of the energy.

日常示例

The sun's energy comes from fusion reactions, though it primarily uses the proton-proton chain rather than D-T fusion.

工业重要性

D-T聚变是ITER国际热核实验堆及众多国家核聚变研究的核心反应。每千克氘氚混合物所释放的能量相当于1000万千克化石燃料。
