Fusion & Spent Fuel
Nuclear fusion: a different mission
Fusion is often presented as the long-term “holy grail” of clean energy. ReCore does not compete with fusion research; it asks a different systems question: what can be done with existing nuclear materials and high-maturity fission building blocks in the nearer term? See Why?.
Technology readiness (contrast)
Fusion remains largely experimental and prototype-scale; commercial deployment is generally estimated for the late 21st century (projects such as ITER and private ventures still address Q, sustained plasma, and materials).
- SFR and metal-fuel building blocks used in ReCore sit at much higher component TRLs than commercial fusion — see ReCore-Reactor.
- Integrated FOAK (Na–N₂ plant + industrial recycle hub) is still engineering and licensing work, not a commercial commodity.
Waste reality
A common misconception is that fusion “solves nuclear waste.”
- Fusion produces new energy from light isotopes (e.g. D–T pathways); it does not fission legacy actinides in LWR spent fuel.
- Legacy spent fuel remains if society switches only to fusion: tens of thousands of tonnes of LWR SNF and long-lived actinides still need a management strategy (Fuel Science.
- Activation waste: fusion structures can become activated by neutrons, creating volumes of radioactive material that still need management — different from TRU waste, not “zero waste.”
Why a fission closed-cycle concept still matters
Even in a future where fusion is abundant, society still needs a strategy for the long-lived waste legacy and for firm low-carbon power on multi-decade horizons.
- Remediation pathway: multi-recycle of actinides in a fast reactor is intended to convert recovered materials into energy and reduce long-term radiotoxic inventory — a fuel-cycle goal, not a claim that ReCore is the “only” technology that can help.
- Bridge in time: fusion commercialisation timelines are long; modular SFR + recycle concepts explore what can be engineered from existing technology classes in the meantime.
