Curio Advances NuCycle Facility Design with Sargent & Lundy to Accelerate Nuclear Fuel Recycling
Curio, a company specializing in advanced nuclear recycling technologies, has taken a major step toward commercializing its NuCycle nuclear fuel recycling platform by appointing engineering firm Sargent & Lundy to begin the design and engineering phase of the facility that will house the technology. The engagement marks an important transition for the company, moving NuCycle from years of scientific research and technology development into the engineering execution stage needed to support large-scale deployment.
The collaboration represents a defining milestone for Curio’s long-term strategy to establish a domestic nuclear fuel recycling capability in the United States. By initiating formal facility design work, the company is laying the groundwork for future licensing, construction, and operation of a commercial-scale plant capable of recycling used nuclear fuel and strengthening the nation’s nuclear energy supply chain.
Moving from Research to Industrial Deployment
For several years, Curio has focused on developing technologies that can safely and efficiently recover valuable materials from spent nuclear fuel. With the science and process development phase progressing successfully, the company is now entering a new chapter centered on engineering implementation.
Sargent & Lundy’s multidisciplinary engineering teams will work to transform Curio’s proprietary process systems into a practical, integrated, and licensable industrial facility. Their responsibilities will include designing the process building, supporting infrastructure, and engineering systems required for future commercial operations.
The engineering work will establish the technical foundation needed for regulatory approval, particularly the licensing process with the U.S. Nuclear Regulatory Commission (NRC). Developing a facility design that satisfies stringent safety and operational standards is considered a critical requirement before construction activities can begin.
The process building itself is being designed with a strong emphasis on operational readiness, maintainability, worker safety, and scalability. These elements are essential for ensuring that NuCycle technology can eventually be deployed at larger capacities and potentially replicated at additional facilities in the future.
Strengthening America’s Nuclear Fuel Cycle
The United States currently stores significant quantities of used nuclear fuel generated from decades of commercial nuclear power production. While this material still contains valuable energy resources, the country has historically lacked a comprehensive commercial recycling infrastructure capable of recovering these materials and reintroducing them into the nuclear fuel cycle.
Curio believes its NuCycle technology can help address this challenge by enabling the recycling and reuse of spent nuclear fuel. Such an approach could reduce long-term waste inventories, improve fuel resource utilization, and support energy security objectives.
Edward McGinnis, President and Chief Executive Officer of Curio, emphasized that the company has reached a pivotal moment in its development journey.
According to McGinnis, Curio has already demonstrated the scientific basis of the NuCycle technology and is now focused on designing a facility that can recycle nuclear fuel at industrial scale. He noted that the project has the potential to strengthen U.S. energy security while contributing to the establishment of a closed domestic nuclear fuel cycle.
Industry analysts increasingly view fuel recycling as a strategic capability as global interest in nuclear power continues to grow. The expansion of advanced reactor technologies, including small modular reactors and next-generation nuclear systems, is expected to increase demand for secure and reliable fuel supplies.
By recovering valuable materials from existing spent fuel inventories, nuclear recycling technologies could provide an additional source of fuel while reducing dependence on newly mined resources.
Leveraging More Than a Century of Engineering Expertise
Sargent & Lundy brings extensive experience to the partnership. The engineering company has played a significant role in numerous nuclear, power generation, and energy infrastructure projects throughout its history.
The company’s expertise in plant design, regulatory compliance, and large-scale energy projects is expected to be instrumental in translating Curio’s innovative technology into a commercially deployable facility.
Shiven Sulkar, Executive Vice President and Chief Nuclear Officer at Sargent & Lundy, described innovation as a central element of the company’s legacy and future growth strategy.
He stated that the partnership with Curio provides an opportunity to combine established engineering methodologies with advanced technologies to create a facility that delivers safety, scalability, and sustainability for the next generation of nuclear power systems.
Sulkar further highlighted that the collaboration reinforces Sargent & Lundy’s role in supporting advanced nuclear solutions that can enhance grid reliability, improve long-term fuel cycle resilience, and expand clean energy capacity across the U.S. electricity market.
Focus on Safety and Regulatory Readiness
One of the most important aspects of the current design phase is ensuring that the future NuCycle facility will satisfy the stringent requirements of nuclear regulators.
The engineering effort will establish a detailed basis for licensing discussions with the NRC, including facility architecture, operational processes, safety systems, and supporting infrastructure.
Regulatory approval processes for advanced nuclear facilities require extensive technical documentation and demonstration that proposed technologies can operate safely under a wide range of conditions.
By beginning engineering activities early, Curio aims to streamline future licensing efforts and position the project for efficient progression toward construction and operation.
The company also intends to ensure that the facility is designed with long-term operational flexibility in mind, allowing future expansion and adaptation as market conditions evolve and additional nuclear recycling opportunities emerge.
Site Evaluation and Concept Development Underway
The initial scope of work includes comprehensive site evaluations and the development of facility design criteria. Engineers will also begin conceptual designs for both the process building and associated support facilities.
These activities are expected to define the layout, infrastructure requirements, utility systems, and operational framework necessary to support the NuCycle technology platform.
The conceptual design phase represents an important precursor to detailed engineering activities, which will eventually include equipment specifications, construction planning, and licensing documentation.
As the project progresses, the engineering studies will help determine how the facility can be integrated into the broader nuclear fuel supply chain while maintaining high standards of efficiency and environmental stewardship.
Supporting the Future of Clean Energy
Nuclear energy is increasingly being recognized as a critical component of global decarbonization strategies because of its ability to provide reliable, carbon-free electricity around the clock.
However, long-term sustainability of nuclear power depends in part on developing more resilient and efficient fuel cycle solutions. Technologies that can recycle used nuclear fuel may play an important role in extending fuel resources, reducing waste burdens, and supporting future reactor deployments.
Curio’s partnership with Sargent & Lundy represents a significant advancement toward these objectives. By moving NuCycle into the engineering and facility design stage, the company is taking a meaningful step toward establishing commercial-scale nuclear fuel recycling capabilities in the United States.
The project also aligns with broader efforts to strengthen domestic energy security, enhance grid reliability, and build a more sustainable nuclear energy ecosystem capable of supporting growing electricity demand in the decades ahead.
With engineering activities now officially underway, Curio and Sargent & Lundy are positioning the NuCycle facility as a potentially transformative project for the future of advanced nuclear energy and the development of a closed and resilient U.S. nuclear fuel cycle.
