RESEARCH QUESTIONS • What's the optimal capacity for a Nuclear-Thermal Energy Storage (TES) plant to maximize revenue? • What's a reasonable dispatch window for the optimization process? • How do market signals affect TES plant size and operations? Workflow for HERON optimization: HERON uses trained electricity price signals as the main economic drivers, implementing cost functions to minimize the expenses related to three TES-coupled High Temperature Gascooled Reactor (HTGR) modules: charger, discharger (including Balance of Power (BOP)), and TES
