Tricastin nuclear power plant

The Tricastin nuclear facility is a large industrial complex in the Drôme region with four pressurized water reactors spread across an extensive site. The installation was developed and is managed by Électricité de France, consisting of separate operational areas for power generation and support functions.

Construction began in 1974, with the first reactor starting operation in 1980. The facility was built during France's major expansion of nuclear power as a national energy source.

The site's name comes from an ancient people who lived in this region, which led local wine producers to rename their appellation to Grignan-Les Adhémar. This connection between the industrial facility and the wine trade shapes how the area sees itself today.

The site is spread out across a large area, so planning your route is helpful to see different sections without wasting time. Wear sturdy shoes and expect to walk between various sections of the facility.

The complex brings together one of Europe's largest concentrations of nuclear industry companies and research centers in a single location. This gathering of expertise makes the area a major hub for nuclear technology development and advancement.
