Reactors

A Proven Technology

High Temperature Gas-Cooled Reactor (HTGR)

X-energy is innovating and building upon decades of research, testing and demonstration of HTGR projects worldwide. We incorporate innovative design features into our reactors that adapt to a variety of markets and customer needs.

Proven technology through more than 30-years of test and operational history.

Each reactor will generate 200MWt and approximately 75MWe. The standard X-energy Reactor “four-pack” plant generates approximately 300MWe and will fit on as few as 13 acres. All of the components for the X-energy Reactor will be road-transportable, and will be installed, rather than constructed, at the project site to streamline construction.

The X-energy Reactor is a 200MWth helium cooled nuclear reactor that features the LEU fuel cycle. The heat source is based on pebble bed technology which has a proven meltdown proof core. Heat transfer is via a proven helical coil steam generator. Small size and modular construction result in relatively low cost. On-line fueling allows for continuous operations.
