Atlas Atomics Overview

About Atlas Atomics

Atlas Atomics is a nuclear technology company developing an improved heavy water reactor design that does not rely on enriched uranium and may therefore be cheaper to build and operate than conventional reactors. Its stated goals are reliable power generation, a larger supply of medical and industrial isotopes, and nuclear fuel recycling. The company operated largely in stealth until October 2026, when Bloomberg reported a Series A of about USD 400 million at a valuation of roughly USD 1.9 billion, led by General Catalyst with Andreessen Horowitz participating. Vivek Ramaswamy co-founded and backs the company, which is led by Kevin Gan. A former Oak Ridge National Laboratory chief operating officer serves as chief nuclear officer.
