WikiZero - Gas turbine modular helium reactor

The Gas Turbine Modular Helium Reactor utilizes the Brayton cycle turbine arrangement, which gives it an efficiency of up to 48% – higher than any other reactor, as of 1995. Commercial light water reactors (LWRs) generally use the Rankine cycle, which is what coal-fired power plants use. Commercial LWRs average 32% efficiency, again as of 1995.

Why can't helium be made artificially? - Quora

The helium that is available commercially is extracted from oil and gas wells. Helium can be extracted from underground because it is trapped by the same sorts of impermeable rock layers that trap petrochemicals. That helium has had thousands or millions of years to accumulate in those rock formations, but we can empty them in a few decades.
