About Us
Elemental Nuclear Energy is an advanced nuclear technology company developing the Inherently-Safe Sodium-Cooled Thermal Reactor (“ISTR”) Power System — a compact sodium-cooled small modular reactor (SMR) — together with supercritical CO₂ (sCO₂) power conversion systems and nuclear-powered infrastructure solutions.
Advanced SMR
Development of an advanced small modular reactor (SMR) with integrated power generation unit.
Brayton Cycle Generator
Development of a non-fossil-fuel Brayton Cycle Generator.
Nuclear Isotopes
Production of nuclear isotopes for pharma and medical uses.
Power Generation Services
A power generation services division.
History
Elemental Nuclear was formed in 2025, bringing together a team with deep experience to pursue a development and commercialization pathway.
Near-Term Revenue
Focused on near-term revenue opportunities.
Long-Term View
Developing our technology with a long-term view.
Why We Are Different
Beyond the technology, it's our philosophy, experience, and drive that sets Elemental Nuclear apart.
Experienced Leadership
Unlike many in the SMR space, our team bridges the gap between theory and reality. We have deep, hands-on experience with operating nuclear reactors, developing new technology, turning concepts into working prototypes, and securing project financing. We don't just design; we build and operate.
Operational Focus
Compliance, leadership, and a daily culture focused on the highest operational standards.
Safety Bias
Safety comes first for our employees, contractors, the community, and the environment.
Collaborative Intelligence
We surround ourselves with world-renowned researchers and practitioners. Learning from others is more cost-effective and faster than learning the hard way.
Fast-Paced
"Proceed with urgency, safely." The world needs power for AI and industry now.
Nimble
Quick decisions and course corrections. We adapt to minimize impacts and keep moving.
Results Oriented
Turning ideas into assets. Producing nuclear power is the only acceptable outcome.
Our Solutions
Pioneering the next generation of energy with safety and efficiency at the core.
Simplicity. Safety.
Reliability.
Elemental Nuclear is developing the ISTR Power System, a compact sodium-cooled small modular reactor (SMR). The ISTR pairs uranium zirconium hydride (U-ZrHx) fuel — the proven fuel form used in TRIGA-type research reactors — with sodium cooling similar to the EBR-II reactor at Idaho National Laboratory. It operates at atmospheric pressure, eliminating high-pressure vessels in an inherently, walk-away-safe system.
Walk-Away Safe
Physics-based safety ensures shutdown without human intervention.
Proven Fuel
Uranium zirconium hydride (U-ZrHx) fuel, with 50+ years of global operating history in TRIGA-type research reactors.
