DIA Launches $1.25M Study for Nuclear Reactor at Airport

Exploring New Frontiers in Sustainable Energy

Denver International Airport (DIA) is taking a bold step towards a greener future by seeking proposals for a feasibility study on the potential implementation of small modular reactors (SMRs). These reactors represent a new generation of nuclear technology that could significantly contribute to DIA's goal of becoming the world’s greenest airport and achieving energy independence.

The proposed study, which could cost up to $1.25 million, is expected to take over a year to complete. It aims to evaluate whether SMRs can be a viable solution for meeting the airport's growing energy demands while supporting its long-term sustainability goals.

A Vision for the Future

Mayor Mike Johnston emphasized the importance of exploring innovative solutions as Denver continues to grow and face the challenges of climate change. “As we work to make DEN the greenest airport in the world, we must explore every innovative solution available,” he stated. “Studying the potential of small modular nuclear reactors is a forward-looking step in understanding how we can deliver reliable, clean energy at scale.”

According to the International Atomic Energy Agency, small modular reactors have a power capacity of up to 300 MW(e) per unit, making them a more compact alternative to traditional nuclear reactors. Their modular design allows for factory assembly and on-site installation, offering flexibility and potentially reducing costs.

Advantages of Small Modular Reactors

Small modular reactors are gaining attention in the clean energy sector for their potential to provide safe, scalable, and cost-effective nuclear power. Unlike fossil fuels, these reactors operate 24/7, making them an ideal complement to renewable energy sources like solar and wind. This reliability could help DIA maintain a consistent energy supply even during periods of low renewable output.

DIA CEO Phil Washington highlighted the airport’s current efforts in sustainability, including solar arrays on 100 acres of land, an expanded electric vehicle fleet, and achieving energy certification for new construction projects. However, with projections indicating that 120 million passengers will pass through the airport annually by 2045, the need for additional energy solutions is becoming increasingly urgent.

The Feasibility Study

The feasibility study will address several key questions, including whether SMRs are practical for the airport, what technologies are available, and what potential costs and risks might be involved. The study will also assess how SMRs could support DIA’s energy demand and clean energy goals while considering the complexities of implementing such advanced technology.

Elizabeth Babcock, executive director of Denver’s Office of Climate Action, Sustainability, and Resiliency, noted that the study is an important step in evaluating different energy options. “As we plan for a growing population and a changing climate, we must carefully assess all zero-emission options that can deliver reliable power,” she said. “We need to weigh potential costs and environmental impacts to ensure a sustainable future.”

A Unique Opportunity

If implemented, this project would mark the first nuclear reactor operating in Colorado, as another reactor in Fort St. Vrain closed in the early 1990s. This initiative represents a significant shift in how the airport approaches energy production and sustainability.

While the technology is still relatively new, DIA is committed to responsible planning and thorough research. The airport recognizes the need for substantial investment and acknowledges the complexity of integrating SMRs into its existing infrastructure. However, by keeping an open mind and continuing to explore all possibilities, DIA is positioning itself as a leader in sustainable aviation and energy innovation.
