AB - Nuclear power plants are commonly used for baseload power supply due to their high reliability, low variable costs, as well as relatively low thermal efficiencies and limited load-following capabilities; especially, in the case of light water reactors. At the same time, concentrating solar power (CSP) technology is gaining attention, but is still considered an intermittent source of power with a limited availability factor. In an effort to propose a very different performance characteristic for both technologies, a hybrid power system combining nuclear and CSP plants and integrated with a thermal energy storage system is considered in this paper. The integration of the technologies is achieved by adding an indirect solar superheater and a solar reheater to a small modular nuclear reactor (NuScale). The work includes modelling of the integrated hybrid system, thermodynamic performance analysis and operational optimization aimed at maximizing the profitability of such a hybrid power plant in Oman. The results show that the hybrid system has the potential to deliver more efficient and flexible power (operating between 55% and 100% of nominal load) with the nuclear reactor operated continuously at its full rated power. The hybridization concept can potentially produce a competitive levelized cost of electricity, especially with the integration of thermal energy storage. The study concludes that the installation of such a system in Oman is not yet economically viable unless electricity tariffs increase by 70% to UK levels.
