A modified price-following model was developed to perform annual simulations, and case studies were performed for systems combining Solar power, wind, and SMR with thermal storage. The results show that, when comparing wind power and solar power as heat source, solar power is more effective in applying thermal energy storage technology because it allows for a larger price differential between heat charging and discharging. It was also found that a stable heat source such as SMRs allows a larger amount of electricity to be sold with the same amount of heat storage material.

To assist conceptual studies of various reactor systems conducted by private sectors in nuclear power innovation, development of an innovative design system named ARKADIA (Advanced Reactor Knowledge- and AI-aided Design Integration Approach through the whole plant lifecycle) is undergoing. In this paper, focusing on the ARKADIA-Design, achievements in the development of optimization processes in the fields of the core design, the plant structure design, and the maintenance schedule planning, as major function of ARKADIA-Design, and numerical analysis methods to be used for the detailed analysis to confirm the plant performance after optimization are introduced at this point in time.
