About this calculator
The D-T fusion reaction, or deuterium-tritium, is one of the most studied and promising reactions for obtaining nuclear energy. It occurs when a deuterium nucleus (a hydrogen isotope with one proton and one neutron) fuses with a tritium nucleus (a hydrogen isotope with one proton and two neutrons), resulting in a helium nucleus and a neutron, releasing 17.6 MeV of energy per reaction.
This reaction is particularly interesting for practical applications because it occurs at a relatively low temperature, about 150 million degrees Celsius, which is lower than the temperatures required for other fusion reactions. The energy released can be efficiently converted into electricity with low emissions of greenhouse gases.
However, nuclear fusion still faces significant challenges to become a viable energy source. One of the main challenges is to confine and heat the plasma (the state of matter in which fusion reactions occur) in a stable and controlled manner. Furthermore, obtaining tritium, which is a rare isotope, is a logistical and economic obstacle.
Despite these challenges, D-T fusion remains an active area of research and development, with the potential to provide a clean, safe, and virtually inexhaustible source of energy in the future.
