Fusion and Nuclear grants

Grants and milestone-based programmes for fusion, advanced fission and small modular reactors. Led by the US DOE (Milestone-Based Fusion Development, ARPA-E), the UK Atomic Energy Authority and STEP, ARIA, and EU Horizon Euratom calls. Listed below are the open fusion and nuclear grant calls in that landscape, taken from each funder's own notice and re-checked on every refresh.

Energy grants divide into two families that rarely share a form. Deployment pots such as the EU Innovation Fund, the US Department of Energy and the UK Net Zero Innovation Portfolio back kit that already works, usually at 30 to 50 per cent intervention rates against matched private capital. Earlier research calls, Horizon Europe and ARPA-E and Innovate UK among them, fund lower technology readiness at far smaller cheques. Applying to the wrong family is the most common reason a strong project scores badly.

This page lists open fusion and nuclear grants currently tracked by Raise Lens — 5 of them right now, sorted with the soonest deadline first. Every listing has been classified against the sustainability taxonomy rather than matched on keywords, so what appears here is fusion and nuclear work rather than anything whose description happens to mention it.

4 distinct funders are publishing the fusion and nuclear grants on this page. Who is funding matters as much as what: eligibility, reporting burden and the realistic timeline to a decision vary far more between funders than between individual calls, which is why the listing names the funder on every opportunity it opens.

2 of these close within the next 30 days. Deadlines are taken from the source listing and re-checked on every refresh, but the originating funder remains the authority — always confirm against the official notice before you submit.
