   - EIB says it is making its first investment in small modular reactor technology.
   - Financing is up to €40 million to Finland-based Steady Energy.
   - The money is InvestEU-backed and supports R&D, testing and licensing in Finland between 2026 and 2028.
   - Steady Energy’s concept is a 50 MW heat-only reactor for low-carbon district heating.
   - EIB says Steady Energy was spun out from VTT in 2023 and is building a non-nuclear pilot facility in Helsinki to test safety systems and support licensing.

## Editorial cautions
- Do not state that Europe has an operating EIB-backed SMR. This is a financing, R&D, testing and licensing development.
- Do not state that LDR-50 will generate electricity for AI data centres; Steady Energy and EIB frame this design as heat-only district heating.
- Do not treat the financing as proof of final regulatory approval, construction start, commercial deployment, cost certainty or subsidy-free economics.
- Not investment advice: any mention of European nuclear policy, SMR suppliers, uranium/fuel markets or listed entities is infrastructure research only.
