Saint-Paul-Trois-Châteaux Cathedral (French: Cathédrale Notre-Dame-et-Saint-Paul de Saint-Paul-Trois-Châteaux or Cathédrale Notre-Dame de Saint-Paul-Trois-Châteaux) is a former Roman Catholic church located in the town of Saint-Paul-Trois-Châteaux, France. It was a national monument. It was formerly the seat of the Bishop of Saint-Paul-Trois-Châteaux. The diocese (sometimes, like the town, also known as Saint-Paul-en-Tricastin) was created in either the 4th or the 6th century and was abolished under the Concordat of 1801, when its territory was divided between the Diocese of Avignon and the Diocese of Valence, known since 1911 as the Diocese of Valence (–Die–Saint-Paul-Trois-Châteaux).

Saint-Paul-Trois-Châteaux (French pronunciation: [sɛ̃ pɔl tʁwɑ ʃɑto]; Vivaro-Alpine: Sant Pau de Tricastin), sometimes known as St-Paul-en-Tricastin, is a commune, an administrative region, in the Drôme department in southeastern France.

The former French Roman Catholic Diocese of Saint-Paul-Trois-Châteaux (Latin: Dioecesis Sancti Pauli Tricastinorum; French: Diocèse de Saint-Paul-Trois-Châteaux), sometimes, just like the town, also known as the Diocese of Saint-Paul-en-Tricastin (Latin: Dioecesis Sancti Pauli Tricastinorum; French: Diocèse de Saint-Paul-en-Tricastin), existed from the sixth century to the French Revolution. Its see was at Saint-Paul-Trois-Châteaux, in the modern department of Drôme, southern France. Its territory was included in the expanded Diocese of Valence, by the Napoleonic Concordat of 1801.

The canton of Le Tricastin is an administrative division of the Drôme department, southeastern France. It was created at the French canton reorganisation which came into effect in March 2015. Its seat is in Pierrelatte. It consists of the following communes:

Pierrelatte (French pronunciation: [pjɛʁlat]; Occitan: Pèiralata) is a commune in the Drôme department in southeastern France. Since the 1980s it hosts one of the biggest production plants of the enriched uranium existing in the world, used both for civil and military purposes.

Roussas is a commune in the Drôme department in southeastern France.

The Tricastin Nuclear Power Plant (French: Centrale Nucléaire du Tricastin) is a nuclear power plant consisting of 4 pressurized water reactors (PWRs) of CP1 type with 915 MW electrical power output each. The power plant is located in the south of France (Drôme and Vaucluse Department) at the Canal de Donzère-Mondragon near the Donzère-Mondragon Dam and the commune Pierrelatte. The power plant is part of the widespread Tricastin Nuclear Site (see below), which was named after the historic Tricastin region. Three out of the four reactors on the site had been used until 2012 to power the Eurodif Uranium enrichment plant, which had been located on the site.

The Georges-Besse plant, known as the Eurodif plant from 1978 to 1988 (for European Gaseous Diffusion Uranium Enrichment Consortium), was a nuclear facility specializing in uranium enrichment by gaseous diffusion. The plant, now in the nuclear dismantling phase, is located on the Tricastin nuclear site at Pierrelatte in the Drôme region. On the initiative of French President Georges Pompidou in late 1969, an agreement was signed between France, Belgium, Italy, and Spain in 1972 to give France complete autonomy over the nuclear fuel cycle. The plant was inaugurated in 1979 and operated for 33 years by Eurodif SA, a subsidiary of Areva NC. Along with Urenco, which operates based on an agreement between Germany, the UK, and the Netherlands, it was the only uranium enrichment plant operating based on a multinational agreement. The Tricastin nuclear site comprises several nuclear facilities, the largest of which are the Tricastin nuclear power plant, the former Georges-Besse plant, and the new Georges-Besse II centrifuge enrichment plant. The enriched uranium produced was used as fuel by French nuclear power plants and many foreign power plants. The enriched uranium produced by this plant supplied around 90 pressurized water reactors, the most widely used nuclear technology in the world, including the 58 French reactors. Eurodif SA's customers included EDF and over 30 electricity companies worldwide, and its main competitors were the United States and Russia.
