Deuterium–tritium fusion reaction energy
One D–T fusion reaction releases about 17.6 MeV, or 2.82 × 10⁻¹² J, shared mainly by a neutron and an alpha particle. This is per reaction, not reactor output.

- Comparing
- Energy ↔ Released energy per reaction
- Relative size
- Deuterium–tritium fusion reaction energy is larger on this measurement by a factor of about 17.6.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Deuterium–tritium fusion reaction energy uses a 2.82 × 10⁻¹² J central value within a recorded range of 2.81 × 10⁻¹² J–2.83 × 10⁻¹² J.
