Conference Article: Influence Of Htgr Parameters On The Configuration And Characteristics Of Power Conversion Unit With Direct Gas-Turbine Cycle

Abstract

A high-temperature gas-cooled reactor has a large potential to be used as a heat source in different production processes because it coolant temperature at the reactor outlet is higher than that in reactors of other types. Besides, the concept of HTGR with a closed gas-turbine cycle for electric power generation with efficiency to 50 % is very interesting. But the inclusion of power conversion unit (PCU) with gas-turbine cycle in the primary circuit of a reactor plant stipulates strict interindependency of a large number of the main plant parameters (reactor capacity, helium temperature and flow rate, turbomachine rotation speed, turbocompressor efficiency, hydraulic losses, etc.). The distinctive feature of such plants is the volume flow rate through a reactor and a turbine strictly determined by designed speed of turbomachine and a generator as a part of it. The primary circuit parameters, in turn, detmine design requirements for equipment and production processes. Thus, the complex analysis for selection of optimal cycle parameters is required to obtain high efficiency of a gas-turbine. This report considers the key parameters influenced the configuration and efficiency characteristics of a power conversion unit (PCU) with direct gas-turbine cycle.
