摘要：
A performance analysis is carried out for a 60 MWth Advanced Atomic Cogenerator for Industrial Applications that is a pebble bed high-temperature gas cooled reactor with an indirect Brayton power conversion system. Four different gases viz. air, CO2, N-2 and He were studied as secondary cycle working fluids. Specific work output and power generation efficiency are calculated. In addition, the total thermal efficiency for the steam production process is estimated. Our results indicate that over a wide range of some operating conditions, helium gives the highest power generation efficiency, while N-2 and air provide a better specific power output. Finally, the highest cogeneration-steaming rate was noticed for the CO2 cycle. (C) 2018 Elsevier Ltd. All rights reserved.
