Data for: Operating scenario of 3GWthClass FFHR power plant with bypass controlled supercritical CO2 gas turbine power generation system
Description
Abstract: In order to achieve high power generation efficiency, facility compactness, high safety, and high coexistence with fuel tritium in the 3GWth class FFHR power plant, optimization, performance and operation scenario of the power generation system of the power plant model using the axial flow type uniaxial supercritical CO2 gas turbine power generation system were examined. As a result, the following conclusions were obtained. The most efficient and compact axial flow uniaxial design supercritical CO2 gas turbine power generation system suitable for 3GWthFFHR power plant has a maximum heat capacity of 1.5MWth×2, and the power generation efficiency at that time was evaluated as 46.2%. Therefore, split connection with two power generation systems is optimal for a 3GWth class FFHR power plant. Here, the operating speed of the turbo equipment was set to 3600 rpm in order to adapt this plant model to the power supply system in Japan.
