Company Profile

X-energy, headquartered in Rockville, Maryland, is developing the Xe-100 — a pebble bed high temperature gas reactor using TRISO fuel particles that cannot melt down by design. Each unit generates 80 MWe, and plants can be built in four-unit clusters of 320 MWe. X-energy was selected alongside TerraPower for the DOE Advanced Reactor Demonstration Program in 2020, receiving up to $1.2 billion in federal cost-sharing. Amazon has signed a power purchase agreement targeting deployment by 2039. Dow Chemical is partnering with X-energy to deploy the Xe-100 for industrial process heat — the first nuclear plant designed to decarbonize heavy industry. Their design certification application is under active NRC review.

Reactor Specs
REACTOR DESIGN
Xe-100 · High-Temp Gas Reactor

Uses helium gas as coolant instead of water. Operates at higher temperature for greater thermal efficiency.

POWER OUTPUT
80 MWe

Powers ~65,040 average US homes. A standard large nuclear plant produces ~1,000 MWe.

COOLANT
Helium

Inert gas that cannot become radioactive. Allows very high outlet temperatures for industrial heat applications.

FUEL TYPE
TRISO Pebbles

Tristructural isotropic fuel: uranium encased in ceramic layers that cannot melt. Each particle acts as its own micro containment vessel.

TARGET OPERATION
2030

US nuclear projects historically require 7–10 years from construction permit to first power. The 2030 target assumes factory-built modular components and no major regulatory delays.

SITE LOCATION
Dow Chemical, TX

Dow Chemical industrial complex. Reactor heat will directly decarbonize Dow's manufacturing processes — the first nuclear-industrial heat application in the US.

Corium Assessment
Independent analysis · Not investment advice
✓ STRENGTH
Industrial heat market is underserved
Dow Chemical partnership targets process heat — a market nuclear has never penetrated. If successful, opens an entirely new demand category beyond electricity generation.
~ WATCH
TRISO fuel supply chain
BWXT is the only commercial TRISO manufacturer in the US. X-energy and Kairos are competing for the same limited supply. Capacity expansion is underway but timeline uncertain.
⚠ RISK
No construction permit application yet
Still at design certification stage. TerraPower and Kairos are 2–3 regulatory stages ahead. The 2039 Amazon target assumes significant acceleration.
