TerraPower Names Hyundai E&C as EPC Contractor for Up to Eight Natrium Reactors
TerraPower has selected Hyundai Engineering & Construction as its engineering, procurement and construction contractor for up to eight Natrium reactors, according to Neutron Bytes. The contract carries completion, price and performance guarantees.
The reactors will supply power to Meta data centers, Neutron Bytes reported.
The underlying deal dates to January 2026, when TerraPower and Meta announced an agreement to develop up to eight Natrium reactor and energy storage system plants rated at 345 MW each, per Neutron Bytes.
On the sizing, Neutron Bytes reported that the buildout would give Meta up to 2.8 GW of carbon-free baseload energy, and that the 500 MW energy storage system built into the Natrium design can push total output to 4 GW.
Each unit pairs 345 MW of baseload output with storage that ramps to 500 MW for more than five hours, according to Neutron Bytes. That ramp profile is the commercial pitch behind the design: a reactor sized for steady output, plus a thermal buffer that lets the plant follow a load curve rather than run flat.
Meta is funding the deployment, with delivery of initial units as early as 2032, Neutron Bytes reported. An EPC award with price and completion guarantees shifts schedule and cost risk onto the contractor, a structure rarely secured by first-of-a-kind reactor developers.
