An assessment has been performed of the scale dependencies of technologies and features of S-CO2 Brayton cycle power converters. Each feature or technology is considered over a range of cycle electrical power output from the current small scale up to 300 MWe. It is found that for a system size of about 10 MWe that nearly all of the features and technologies prototypical of a full-size system could be incorporated into a next-step demonstration of the S-CO2 Brayton cycle.
