Abstract

Abstract

To solve the problem that traditional PWR nuclear power units cannot meet the need to participate in grid peak regulation in the future, an Solar-Nuclear-Storage Hybrid System that couples solar energy and nuclear energy was put forward. A system model was built with thermal system simulation software EBSILON, where exergy analysis of the system under different operation strategies was carried out to study the thermodynamic performance of the system under design conditions. The exergy analysis and research under different operation strategies show that the three equipment with the highest exergy losses in the system are steam generator, solar field and steam turbine high pressure cylinder first stage, and the exergy loss of the three equipment in total is close to 50% of the total exergy loss. At the same time, the exergic efficiency of solar field is mainly affected by the change of direct normal irradiance. The exergic efficiency of electric heater is basically unchanged with the maximum change of 2% under different operation strategies.
