Recent research conducted by Roger Lew from the Virtual Technology and Design at the University of Idaho has introduced a new approach to optimizing the operation of nuclear power plants, specifically focusing on the thermal power dispatch (TPD) from pressurized water reactors (PWRs). This innovative work, published in the journal ‘Energies,’ explores how nuclear plants can provide thermal energy to nearby industrial processes, thereby enhancing their role in reducing carbon emissions.
The study presents a reduced-order model that simulates the essential dynamics of a PWR while allowing for the extraction of steam to supply industrial applications, such as clean hydrogen production. By enabling the use of nuclear heat in industrial processes, this model not only contributes to lowering greenhouse gas emissions but also opens new revenue streams for nuclear operators. Lew emphasizes the transformative potential of this approach, stating, “The reduced-order simulator can reliably calculate the steady-state and transient response of a PWR plant for thermal power dispatch.”
As the energy market becomes increasingly competitive, particularly with the rise of low-cost renewable sources like wind and solar, traditional nuclear power faces challenges. The operational costs of nuclear plants remain relatively high, especially when they need to curtail power production, which can lead to significant financial losses. The flexibility offered by TPD systems allows nuclear plants to adapt more readily to market demands, potentially allowing them to operate more efficiently and economically.
This research holds significant implications for the energy sector. By integrating TPD capabilities, nuclear power plants can provide not only electricity but also high-quality thermal energy to industrial processes, effectively acting as a combined heat and power source. This dual functionality can enhance the viability of nuclear energy in a landscape increasingly dominated by renewables. As Lew notes, “The relative simplicity of the RO-PWR simulator provides key benefits in understanding and providing approximate validation of the results from higher-fidelity models.”
Moreover, the ability of the RO-PWR simulator to run in real time and connect with physical systems for hardware-in-the-loop testing paves the way for practical applications in the field. This could lead to improved operational strategies that optimize the dispatch of both thermal and electrical power, ultimately benefiting energy producers and consumers alike.
The findings of this research suggest that nuclear power can play a crucial role in the transition to a low-carbon energy future, particularly as industries seek sustainable solutions. By leveraging nuclear heat, companies can reduce their reliance on fossil fuels and lower their carbon footprints, contributing to broader climate goals.
As the energy sector continues to evolve, the integration of advanced modeling techniques like the RO-PWR simulator could help nuclear power maintain its relevance and competitiveness in a rapidly changing landscape. The potential for commercial partnerships and innovative applications in industrial settings highlights the importance of ongoing research in this area.
