Brayton cycle nuclear reactor

WebFeb 14, 2024 · The space Brayton nuclear reactor system usually adopts the helium–xenon gas mixture (He–Xe) as the working fluid. The flow of He–Xe in the micro channel regenerator of the system is generally laminar. WebThe Brayton cycle has higher thermoelectric conversion efficiency than other conversion methods. It can convert approximately 20% to 35% of the whole thermal energy transported by the reactor part into electrical energy through dynamic mechanical processes [ 2 ].
