TECHNOLOGY EXPLORER
A definition before a comparison.
Selected educational profiles. Scale and source stage are separate dimensions, not a ranking.
| Profile | Scale label | Evidence stage | What to keep in view |
|---|---|---|---|
| AP1000Pressurised-water reactor | Large | Operating examples | Established design with operating projects; a new site still needs its own approvals. |
| BWRX-300 — DarlingtonBoiling-water SMR | Modular | Construction | The Canadian regulator records one unit under construction. Operating permission is a separate step. |
| AP300 — US engagementPressurised-water SMR | Modular | Development / review | The US NRC describes pre-application engagement for a future design-certification application. |
| EPR — Flamanville examplePressurised-water reactor | Large | Dated grid milestone | First grid connection reported on 21 December 2024. This is a dated milestone, not a current availability claim. |
| EPR2 programmeNew-build programme | Large | Development / review | EDF describes its EPR2 programme. Programme plans do not establish operation at a proposed site. |
| NUWARD platformDeveloping electricity and heat platform | Modular | Development / review | Vendor terminology and configuration are evolving. Verify current project and licensing evidence. |
These six examples are not a technology shortlist or a database of approved designs. Stage labels refer to the cited context, not every project using that name. “Modular” follows vendor terminology; not every marketed SMR platform uses the same module definition.
