Our Path

ArrowArrow

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.
