As #KansasCity prepares to welcome fans from around the world, it's a reminder that hosting a global event takes more than what happens on the field. It takes reliable infrastructure, dependable power, and communities that know how to get big things done. Just down the road in Parsons, Kansas, @DeepFission is applying that same spirit of ingenuity and practical problem-solving that has long defined the region. We're working to expand access to reliable, affordable electricity through a new approach to proven #nuclear technology. The goals may happen on the field, but dependable infrastructure helps keep everything moving. ⚽ Learn more: deepfission.com/about-us #KansasCity #NuclearEnergy #WorldCup

Can a #nuclear reactor operate more than a mile underground without affecting groundwater? 🤔 When it comes to our plans to place our pressurized water reactors one-mile underground, protecting groundwater is a top priority. Learn more: deepfission.com/faq #NuclearEnergy

For 7 decades, LEU has been used in commercial #nuclear power generation and remains the most common fuel used in pressurized water reactors. We aim to utilize PWR tech LEU fuel as part of our approach to underground nuclear deployment @DeepFission. ⚛️ deepfission.com/technology
