{wiki=Category:Nuclear_fusion_fuels}
Nuclear fusion fuels are materials used in the process of nuclear fusion, where two light atomic nuclei combine to form a heavier nucleus, releasing a significant amount of energy in the process. The most commonly researched fuels for nuclear fusion include: 1. **Deuterium (D)**: This is an isotope of hydrogen that contains one proton and one neutron in its nucleus. Deuterium is abundant in seawater, making it a widely accessible fuel source.
