The recent study funded by the U.S. Department of Energy under the Gateway for Accelerated Innovation in Nuclear (GAIN) initiative marks a significant advancement in the evaluation of small modular reactors (SMRs) for chemical manufacturing applications. Collaborating engineers from NuScale and Oak Ridge National Laboratory (ORNL) conducted a comprehensive techno-economic assessment (TEA) using real-world chemical plant conditions and historical data. This assessment builds upon a previous analysis from 2020, where ORNL explored the potential of advanced SMRs, particularly NuScale’s 50 MWe reactor design, in meeting energy demands at the Eastman Chemical Plant.
Focus on Advanced Reactor Design
The current study shifts attention to NuScale’s enhanced 77 MWe reactor design, which gained regulatory approval in May 2025. This design incorporates several key features, including a high-temperature, high-pressure steam heat-augmentation system, updated capital cost estimates, a streamlined 10-day refueling process, reduced staffing requirements, and improved capacity factors. Additionally, it employs a new methodology for defining the Emergency Planning Zone at the site boundary.
The introduction of these enhancements resulted in “significantly more positive results” compared to the earlier 2020 findings. The analysis concluded that the combination of NuScale’s steam heat-augmentation capabilities allows it to effectively meet the power and steam demands of large chemical facilities while providing additional capacity in a manner that is reliable, cost-efficient, and flexible.
Profitability and Flexibility of Modular Designs
Modeling outcomes from the study revealed that a scalable configuration consisting of 12 NuScale modules offers the optimal blend of profitability, availability, and operational flexibility. However, even a minimum configuration of four modules, paired with traditional boilers, can fulfill the comprehensive energy needs of a chemical plant.
This flexibility allows chemical plants to adapt their energy sources to meet varying demands, ensuring a steady supply of energy while optimizing operational costs. The integrated energy system proposed can deliver 1.3 million kg/h of process steam at a temperature of 400°C and a pressure of 4.1 MPa, alongside generating 73 MW of electric power. Notably, any surplus electricity can be sold back to the grid, enhancing overall profitability.
Industry Implications and Expert Insights
José Reyes, co-founder and Chief Technology Officer of NuScale, highlighted the company’s pioneering role in advancing new technologies for industrial heat and electricity production. He emphasized that the ability to deliver high-temperature steam through NuScale’s scalable architecture grants industrial users unmatched flexibility, enabling seamless integration into existing processes. This innovation opens avenues for chemical plants to explore more sustainable and efficient energy solutions.
The NuScale Power Module, operating as a pressurized water reactor, consolidates all necessary components for steam generation and heat exchange into a compact 77 MWe unit, utilizing standard light water reactor fuel. A full-scale plant comprising 12 modules can achieve a remarkable output of up to 924 MWe of electricity, underscoring the system’s capacity to significantly contribute to industrial energy needs.
Future Directions in Energy Production
The findings from this study not only validate the application of SMR technology within the chemical sector but also suggest a broader potential for decarbonization efforts across various industries. By leveraging advanced nuclear technologies, facilities can reduce their carbon footprint while maintaining energy reliability.
As industries increasingly prioritize sustainability, the insights gained from this research underscore the potential for innovative energy solutions to transform traditional manufacturing processes. The integration of SMRs could play a pivotal role in achieving energy independence and resilience for chemical plants and beyond.
