Elemental Nuclear Energy

What Elemental Nuclear Energy does

Elemental Nuclear Energy is a privately held, Omaha-headquartered nuclear technology company formed in 2025 that is developing three revenue lines: the TSR (TRIGA-fueled Sodium Cooled Reactor), a 25 MWth/10 MWe atmospheric-pressure small modular reactor targeting commercial availability in 2031-2032; the BCG, a non-nuclear compact Brayton Cycle Generator that uses helium as a working fluid to convert thermal energy into electricity and currently produces a demonstrated 2-3 kW electrical output; and NuCore Isotopes, a majority-owned subsidiary commercializing medical and pharmaceutical nuclear isotopes. The reactor combines TRIGA fuel (50+ years of operational history) with sodium cooling and is designed to be walk-away-safe through physics-based inherent shutdown, eliminating the high-pressure vessels typical of light-water reactors.

The company's go-to-market is enterprise-direct, with stated focus on AI data center hyperscalers, heavy industrial buyers (chemicals, petrochemicals, aluminum smelting, cement), and medical/pharmaceutical institutions via NuCore. Pricing is not publicly disclosed and is custom/quote-based. The BCG and isotope operations are positioned as nearer-term revenue pathways while the TSR advances toward NRC licensing and first-of-a-kind deployment. The April 2026 partnership with the University of Utah, covering the first-ever electricity generation from a TRIGA reactor powering a live GPU workload, is the company's primary public demonstration of the BCG/TSR technical stack and involves collaborators from 12 universities across the U.S. and internationally.

Elemental Nuclear is led by CEO David R. Blythe (23 years commercial nuclear operations and regulatory experience, founded Monte Cristo Engineering & Development in 2005), Founder/Chair Michael S. Luther (40+ years of PE/VC and special-situations finance at Deutsche Bank and others), and Chief Nuclear Officer Dr. Junaid Razvi (decades at General Atomics, former director of the global TRIGA research reactor program). The company has no disclosed funding rounds, no disclosed headcount, and no disclosed revenue. Operating geographies are reported as North America; commercial SMR delivery is targeted for 2030-2031, with full TSR commercial availability in 2031-2032.

Core offering

Elemental Nuclear Energy develops the TSR (TRIGA-fueled Sodium Cooled Reactor), an advanced small modular reactor (25 MWth / 10 MWe) that operates at atmospheric pressure with physics-based inherent safety, targeting commercial availability in 2031-2032. The company also produces the BCG (Brayton Cycle Generator), a non-nuclear closed-cycle helium power conversion system, and operates NuCore Isotopes, a majority-owned subsidiary that produces and supplies nuclear isotopes for medical, pharmaceutical, and research institutions.

Product overview

Elemental Nuclear Energy is a multi-dimensional company offering a portfolio of nuclear and non-nuclear power solutions. The core product portfolio consists of the TSR (TRIGA-fueled Sodium Cooled Reactor), an advanced small modular reactor design targeting commercial availability in 2031–2032 with 25 MWth/10 MWe capacity, and the BCG (Brayton Cycle Generator), a non-nuclear Brayton cycle power system that can operate with or without nuclear heat sources. The company also operates NuCore Isotopes as a majority-owned subsidiary focused on medical isotope production, and maintains a power generation services division. The company was formed in 2025 and targets delivery of commercially viable nuclear microreactors by 2030–2031.

One partnership is on record.

• University of UtahcoreStrategic or Co-development Partner · 28 April 2026Elemental Nuclear partnered with the University of Utah's Price College of Engineering for a landmark proof-of-concept demonstration. The collaboration involves connecting Elemental Nuclear's compact cold-helium Brayton Cycle generator to the university's TRIGA reactor, enabling it to generate electricity for the first time in its 50-year history to power a live GPU node running real AI workloads. The project brings together students and faculty from 12 universities across the U.S. and internationally. This represents the first time any university reactor has generated electricity for computing.
