Nuclear power uprates is a process applied to existing nuclear power plants to increase their licensed thermal or electrical output. This involves technical modifications, safety analyses, and regulatory approval to operate the plant at a higher power level than originally licensed. As a research concept, it investigates the engineering challenges, safety margins, regulatory requirements, and economic benefits associated with enhancing the power generation capacity of operational nuclear reactors. Key characteristics include detailed analysis of core physics, thermal-hydraulics, plant systems, and fuel performance under increased power conditions, demonstrating continued compliance with safety limits, and navigating the necessary licensing amendments. Its significance lies in its potential to increase baseload electricity generation from existing infrastructure, improve plant economic viability, and contribute to energy security and decarbonization goals efficiently.
