Abstract
The closed Brayton cycle (CBC) is a promising power conversion unit (PCU) to convert heat from the reactor to electric power for high-power space nuclear power system (SNPS) because of its high efficiency, small volume, light weight and stable operation. To ensure system redundancy and eliminate the gyrostatic effect, the SNPS usually uses multiple Brayton loops (SNPS-MBL), with each Brayton loop sharing one reactor. For the SNPS-MBL, the startup characteristic is an essential part. In this study, the simulation model of the startup was established. The startup processes of simultaneous startup and sequential startup for SNPS with dual Brayton loops (SNPS-DBL) were compared and analyzed from the electric perspective, and the effect of mechanical load torque on the startup process was further analyzed. This study provides a reference for the starting process of the SNPS from an electric perspective.
