Our approach

Safe by physics and design.

No stored energy to release, nothing that moves in the core, and decay heat that leaves to the outside air with no power and no operator action.

01 / The design

Eight features.
One unit.

What Aegis-1 does, and what it leaves out.

  1. Safety without stored energy

    Low pressure with nothing to release, no water to flash, no sodium to burn, no fuel rods to fail. Decay heat leaves to outside air with no power and no operator action.

  2. Nothing moves, low pressure

    No pumps, no moving parts in the core, no secondary fluid inside the reactor boundary, and a primary system that runs at low pressure.

  3. Continuous refueling

    Refueled while running, with no refueling outages. The sealed unit is replaced at the end of its service, not repaired.

  4. Flexible fuel

    Designed to run on commercial uranium fuel, on recycled used-fuel actinides, or on thorium blends, without ever needing separated plutonium.

  5. Net waste consumer

    Consumes more long-lived waste than the plant produces, by taking recycled actinides as fuel.

  6. Power and heat above 700 °C

    Electricity and industrial process heat from one plant, in any mix, from a quarter of rated power to full power.

  7. No water, no exotic chemistry

    An open-air Brayton cycle needs no cooling water, and the plant contains no sodium, no graphite, no beryllium and no tritium-producing lithium.

  8. Grows in 5 MWe units

    One unit is 5 MWe; twenty make a 100 MWe plant, added as the site grows. Each unit is factory-built and road-transportable.

02 / On site

How a plant fits
a customer site.

Where it sits, what leaves it, and what it does not need.

A plant on a customer site Inside a fenced customer site, a plant of 5 MWe units rejects heat to the air and sends electricity and process heat above 700 °C directly to a data center or industrial building. The utility grid sits outside the fence. CUSTOMER SITE, ON-SITE POWER AND HEAT … 5 MWe units Aegis plant 5 MWe per unit, up to 20 units per plant Heat rejected to the air No cooling water Electricity Process heat above 700 °C Data center or industrial load Served directly, on site Utility grid outside the fence
Swipe sideways to see the whole diagram. Units are added on the customer's site and serve the load directly; heat leaves to the air, and the grid stays outside the fence.
  1. Added as the site grows

    One unit is 5 MWe. Twenty make a 100 MWe plant, and each unit is factory-built and arrives by road.

  2. Heat goes to the air

    An open-air Brayton cycle needs no cooling water, and decay heat leaves to outside air with no power and no operator action.

  3. Two products, any mix

    Electricity and industrial process heat above 700 °C, from a quarter of rated power to full power.

  4. Replaced, not repaired

    Each sealed unit is refueled while running and replaced at the end of its service.

Designed for real demand

Power where
it matters most.

Data centers, industrial heat, remote and critical sites, and waste consumption.
