Track SMR companies, designs, and deployment projects
SMRMap is an independent, source-linked directory of small modular reactor and labeled microreactor deployment projects, the organizations behind them, and their designs. It is curated coverage — not a complete global inventory, and not investment advice.
First release covers a curated cohort of well-evidenced SMR and labeled microreactor deployment projects across several countries. It is NOT a complete global inventory of every announced SMR concept, vendor brochure, or large-reactor site. Detailed inclusion rules live on the Methodology page. Project counts mean this dataset's coverage — “no projects tracked here” is not “no projects exist.”
