	<onlyinclude>The '''Brayton cycle''' is a [[thermodynamic cycle]] used in some [[heat engine]]s. Notably, it is used for [[gas turbine ~~engine~~]]s and some jet engines. </onlyinclude>The cycle consists of compressing ambient air, mixing the air with fuel, then igniting the mixture, which expands, doing work. In many Brayton cycle engines, the hot air can then be recycled, heating the fresh air coming through. This increases efficiency, because less fuel is needed to heat the fresh air. In physics terms, the cycle consists of [[adiabatic]] compression and expansion paired with [[isobar (pressure)\|isobaric]] heating and cooling, and allows for increased [[efficiency]] over some other cycles.<ref>D.

Some designs for [[nuclear power plant]]s have toyed with the idea of using a Brayton cycle, such as the South African [[Pebble-bed modular reactor]].<ref>A. Koster, R. Matzie and D. Matzner, "Pebble-bed modular reactor: A generation IV high-temperature gas-cooled reactor," ''Proceedings of the Institustion of Mechanical Engineers, Part A: Journal of Power and Energy,'' vol. 218, no. 1, pp. 309-318, 2004.</ref> and certain [[molten salt reactor]]s. This would require using heated gas from the reactor core to power the [[turbine]]s. However, the large amount of research and development needed to implement this has so far been a barrier preventing success. The majority of nuclear reactors instead use a [[Rankine cycle]] steam engine, so current gas-cooled models must use this heated gas to heat water in turn for the steam engine turbines.
