<5% Enrichment

Standard Low-Enriched Uranium

Our reactor uses only off-the-shelf LEU fuel with existing licenses, the same fuel that supplies nearly 10% of global electricity.

300+

Operating Reactors

Proven PWR Technology

The PWR-20 leverages decades of operational experience, based on the pressurized water reactor platform in 300+ plants worldwide operating at over 90% utilization rate.

1,000-Ton Vault

Hermetically Sealed Containment

Our proprietary steel containment design features a double-hermetic seal and maintenance-free components, enabling permanent isolation of nuclear material.

114 Sq. Ft.

Ultra-Compact Nuclear Island

Our fully-integrated reactor module would occupy a single parking space. The design is optimized for minimal land use, enabling siting at or near industrial facilities and data centers.

Factory-Built

Modular Steam Plant

When paired with Last Energy's modular power plant, the PWR-20 occupies less than 0.5 acres. This combination enables full factory fabrication and accelerated power delivery.

20 MW Electrical

Scalable in Clusters

Each reactor delivers 80 MW thermal at 300°C or 20 MW electrical at medium voltage power. Additional units can be deployed in parallel or sequence, scaling capacity or duration as needed.

PWR-20

Engineered for modular, factory production.

Last Energy designs a mass-production pressurized water reactor, utilizing advanced manufacturing technologies to deploy next generation nuclear power at scale.

PWR-20

Flexible Power Delivery, Predictable Price

The PWR-20 delivers secure, 24/7 baseload energy with stable, long-term pricing through Power Purchase Agreements. Customers, such as data centers and industrial facilities, can connect "behind-the-meter."
