Supercritical CO2 Brayton Cycle Development Gary E. Rochau, Technical Area Lead Advanced SMR Energy Conversion Supercritical CO2 (sCO2) Brayton Cycle sCO2 Brayton Cycle remains in a single-phase throughout the process and does not require added energy to convert from liquid to gas phases or condense gas to liquid like traditional the Rankine Steam Cycle , leading to greater energy conversion efficiency At operating temperatures, sCO2. has high enthalpies (energy/mass). and physical densities greater than steam which minimizes the volume of working fluid and system size Critical Point required for an equivalent energy 304 K = 31 C. bar = MPa conversion reduces capital cost June 5, 2014 Nuclear Energy Advisory Committee Briefing 2.
