HALEU:
High Assay Low Enriched Uranium, enriched up to 19.75% 235U
HALEU fuel gives Gen IV reactors many advantages over older designs. HALEU enables a range of benefits including compact advanced modular reactor designs and extended refuelling cycles, reduced nuclear waste, and enhanced operational flexibility.

- Current commercial light water reactors use Low Enriched Uranium (LEU) fuel at <5% 235U content.
- Most next-generation 'Gen IV' advanced and micro reactors require HALEU.
- There is currently no commercial supplier of HALEU in the Western world and supply side constraints lag demand projection significantly.
Nuclear Waste Recycling
Depleted tails from other uranium enrichers produce nuclear waste that requires adequate management
We believe that our technology can process this waste into HALEU - potentially providing a solution to this growing environmental problem.
This should allow us to produce HALEU at highly competitive prices.
