Our Path

ArrowArrow

Our path towards a safe, clean, & healthy future.

creating sustainable energy.

Fissionaire's development plan consists of three deliberate phases. Each step is achievable with todays materials and supply chains, commercially valuable, and aligned with our ultimate goal - transforming how the world produces clean sustainable energy.

Phase 1
Validation & Test Reactor
(10 MW) “Weinberg One” Reactor

From laboratory proof to full-scale demonstration of a micro-reactor. We are moving quickly to build and operate a (TS-MSBR) thermal-spectrum molten salt breeder test reactor. Designed to validate engineering and operation. It will be capable of producing half of the world demand for specific medical isotopes.
2030
Animation: Fly-over of test site, zoom into the reactor core to see the first fission happening, zoom out on a horizontal plane to show medical isotopes being pulled and shipped.

Phase 2
Factory Built
Micro-Reactors
(Under 200MW)  FA-5; FA-20

Designed for microgrids such as islands, the Permian Basin, AI datacenters, deployable power for military bases, disaster relief, local desalination, and nuclear waste reduction - all while vertically integrating a highly specialized and valuable nuclear engineering and manufacturing company.

  • Minimal Horizontal infrastructure
  • Off-Grid Applications
  • Desalinate from deep water aquifers
  • Light weight for Space Deployment
2032
Animation: Flip through images of deployed reactors. military, agriculture, hospitals, drinking water, disaster relief, running oil dereks, Permian basin etc.

Phase 3
Clean Power for the World
(300MW; Modular GW)  WFA-300; FAP-4

Grid-capable reactors delivering clean electricity, large-scale desalination for sustainable agriculture for communities across the globe.
2034
Animation: Space view of earth, zoom into powerlines, down the power lines into the small footprint powerplant tied to the grid. Maybe zoom into the glowing core, zoom out to that glow being the sunsetting over the mountains or a lake etc.

Our path towards a safe, clean, healthy, And sustainable future.

3 deliberate phases.

Fissionaire's development plan consists of three deliberate phases. Each step is achievable based on today's materials and supply chains, commercially valuable, and aligned with our ultimate goal—transforming how the world produces clean sustainable energy.

The Fissionaire TS MSBR is designed with safety and efficient licensing as two of the key principles. Using Advanced Reactor Design Criteria standards upfront ensures safety and streamlined licensing are inherent in our design. 

Phase 1
Our Test Reactor
(10 MW) “Weinberg One” Test Reactor

We are moving quickly to build and operate a (TS-MSBR) thermal-spectrum molten salt breeder test reactor. Designed to validate the engineering and operation of our fuel salt processing technology. It will be capable of providing high demand medical isotopes.
2030
Phase 2
Factory Built
Micro-Reactors
SIERRA micro-reactors

Designed for microgrids such as islands, off-grid industry, AI datacenters, deployable power for military bases, disaster relief, and local desalination—all while vertically integrating a highly specialized and valuable nuclear engineering and manufacturing company.

  • Off-Grid Electricity
  • Desalination
  • Direct Heat
  • Transportable
  • Modular & Expandable Power
2032
Phase 3
Clean Power for the World
300MWth Parallel to GW+

Grid-capable reactors delivering clean electricity, industrial process heat, and large-scale desalination for fresh water. Incorporates high temperature ceramic materials and moderator that will last the life of the plant.
