## 🌍 ABOUT US

NPX https://www.npxinnovation.ca partners with nuclear utilities and new reactor projects to unlock performance through innovation. We combine decades of nuclear operation expertise with AI, digital tools, and lean processes to help plants run safer, smarter, and more cost-effectively.
