The analysis of the worlds energy needs shows them in historical growth, with the highest per capita demand concentrated in the developed countries. Nuclear Fusion is a candidate as a long-term energy solution, for developed countries. The recent stress on safety by the world community has stimulated the research on other fuel cycles than the Deuterium-Tritium (DT) one, based on 'advanced' reactions, such as Deuterium-Helium-3 (D-He-3). With these cycles, it is not necessary to breed and fuel tritium. The D-He-3 cycle has also a very low presence of fusion neutrons. The plasma confinement requirements for a D-He-3 reactor are more challenging than those for a DT reactor, and He-3 is not currently available on earth. As an important step towards the study of a D-He-3 reactor, a feasibility study of a high-field D-He-3 experiment of relatively large dimensions and high fusion power, however based on present technologies, has brought to the proposal of the Candor fusion experiment. Terrestrial sources of He-3 are very small. However, a major deposit of He-3, originally discovered in lunar samples in 1970 was considered by the fusion program in 1986. The He-3 of the moon is contained in the regolith, roughly a million t. A cost and energy balance assessment to feed the Candor experiment has been performed, based upon available data. It turns out that He-3 feed for a large experiment such as Candor can be a good demonstration technological step for lunar D-He-3 mining. The D-Ve fusion cycle offers strong safety advantages and could be the ultimate response to the environmental requirements for future nuclear power plants.
