What these terms mean
Every classification on this page, defined. These are controlled-vocabulary terms, so the same word means the same thing on every profile.
- Reactor developer
- Develops a fission reactor design. Carries no implication that anything is licensed, funded or built.
- Fission
- Advanced and small modular fission reactor developers, plus established reactor vendors.
- Pressurised water reactor › › Pressurised water reactor
- Water kept under high pressure so it heats without boiling, transferring heat to a separate steam loop. The most common reactor type in service worldwide.
- Low-enriched uranium
- Below 5% U-235.
In Last Energy’s own words
Quoted from the organisation’s own site as we archived it. Their description of themselves, not ours, and not a claim this site has checked.
Our reactor uses only off-the-shelf LEU fuel with existing licenses, the same fuel that supplies nearly 10% of global electricity.
Our proprietary steel containment design features a double-hermetic seal and maintenance-free components, enabling permanent isolation of nuclear material.
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.
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.
Last Energy designs a mass-production pressurized water reactor, utilizing advanced manufacturing technologies to deploy next generation nuclear power at scale.
Our goal is to decarbonize global energy production, increase access to dependable power, and create a scalable clean energy future for humanity by significantly reducing the time and cost to deploy nuclear power plants.
Last Energy has taken a first-principles approach to what we believe is the defining challenge of our time: how to deliver abundant, reliable energy fast enough to support modern industry and economic growth.
Last Energy radically simplifies nuclear deployment by building, owning, and operating power plants for customers. Our full-service model combines proven reactor technology with proprietary steel containment to deliver reliable on-site power without requiring customers to develop, finance, or operate the asset.
Last Energy aims to provide reliable, affordable nuclear power at scale by combining its technology with a power purchase agreement business model, serving as the designer, owner, operator, and behind-the-meter independent power producer.
Last Energy aims to provide on-premises baseload power for energy intensive industries and utilities.
Our full-service delivery model, paired with a factory produced, fully modular building approach, and proven technology accelerates time to operation.
