Feasibility of lunar Helium-3 mining
It was found that the most critical element is the lunar mining operation itself. To supply 10% of the global energy demand in 2040, 200 tons of Helium-3 would be required per year. The resulting regolith mining rate would be 630 tons per second, based on an optimistic concentration of 20 ppb Helium-3 in lunar regolith.

Helium Supply, Present and Future
In the United States the lowest practical helium concentration that can economically justify extraction is typically around 0.3 percent by volume. Sometimes, however, the helium is not extracted from high-concentration natural gases and is simply vented to the atmosphere when the natural gas is burned as fuel.

Studies on helium-3 separation at Cernavoda nuclear power plant
A theoretical calculation of the amount of helium-3 produced so far is presented. The production rate of helium-3 is related to the concentration of tritium in the heavy water from the moderator circuit. The solubility of helium-3 in water is very low, therefore almost all of it will be found in the moderator cover gas.
