About The Nuclear Company

The Nuclear Company (TNC) is transforming the nuclear energy sector by streamlining execution, leveraging advanced technology, and fostering a strong culture of safety, quality, and operational excellence.

TNC operates as a fleet-scale nuclear power developer, bringing a disciplined, execution-focused approach to an industry that has historically struggled with cost overruns and schedule delays. By leveraging proven technologies and innovative digital solutions, we're building nuclear plants faster, cheaper, and safer than ever before.

We believe that detailed, executable plans—constantly evaluated and refined—are central to achieving long-term success. Our dedicated teams work in parallel across all phases, ensuring the readiness and smooth execution of the entire project.

About Nuclear OS

In partnership with Palantir Technologies, TNC is developing Nuclear OS - a secure, AI-native digital platform that serves as an integrated operating system for managing every aspect of nuclear plant construction and commissioning. Nuclear OS consolidates formerly siloed data (engineering plans, project schedules, supply chain information, and more) into a unified digital twin, enabling real-time visibility, predictive analytics, and AI-driven decision support.

This is the first AI-driven, real-time software system built for nuclear construction, transforming nuclear project delivery from a high-risk endeavor into a data-driven, predictable process.
