Dampierre-1
Status: Operating critical since March 15, 1980 Reactor status full glossary → Announced Publicly announced — a site and design are proposed, but construction has not begun. Site preparation Early site and civil works are under way; the first safety-related ("nuclear") concrete has not yet been poured. Under construction Formal construction has begun, marked by the first nuclear concrete. Fuel loaded Nuclear fuel has been loaded into the core. The reactor is fuelled but has not yet gone critical. Critical Has reached first criticality — a self-sustaining chain reaction, usually at low power — but is not yet connected to the grid. Grid connected Synchronised to the electrical grid and exporting power for the first time, but still in commissioning and power-ascension testing — not yet in commercial service. In commercial operation — the operator has formally declared the unit in regular commercial service. Shut down Permanently shut down and no longer generating; may be defuelled, undergoing decommissioning, or preserved in place. Canceled Abandoned before completion.
Site: Dampierre-en-Burly, Loiret
First of four CP1-series 900 MWe pressurized water reactors at the Dampierre plant on the Loire, and among the earliest units of France's standardized CP1 fleet built by Framatome for EDF. Part of the rapid nuclear buildout that made France one of the most nuclearized grids in the world.
