Company Overview
About X-energy
X-energy is a nuclear energy company developing the Xe-100 pebble-bed high-temperature gas-cooled small modular reactor (SMR), the closest advanced reactor to actual construction groundbreaking in the United States. The company raised $700 million in Series D financing in November 2025 and in April 2026 signed a project management contract with Fluor — one of the world's largest engineering and construction firms — for the Seadrift, Texas facility that will be North America's first grid-scale advanced reactor serving an industrial customer (Dow).
Business Model & Competitive Advantage
The pebble-bed design is inherently walk-away safe: TRISO fuel pebbles are coated in layers of carbon and ceramic that retain fission products even in loss-of-coolant accidents without requiring emergency cooling systems. This passive safety design enables siting closer to industrial facilities than traditional light-water reactors, making X-energy's partnership with Dow for industrial heat and power particularly compelling.
Competitive Landscape 2025–2026
X-energy has executed multiple supply chain contracts in 2026 — including a $100 million+ graphite supply deal with SGL Carbon and a gigawatt-scale deployment letter of intent with Talen Energy — indicating the company is moving from permitting into active build preparation. Fluor's involvement brings tier-1 construction execution capacity, the critical bottleneck for nuclear plant delivery timelines.
