Codolet (French pronunciation: [kɔdɔlɛ]) is a commune in the Gard department in southern France.

ASTRID (Advanced Sodium Technological Reactor for Industrial Demonstration) was a proposal for a 600 MW sodium-cooled fast breeder reactor (Generation IV), proposed by the Commissariat à l'énergie atomique (CEA). It was to be built on the Marcoule Nuclear Site in France. It was the successor of the three French fast reactors Rapsodie, Phénix and Superphénix. The main goals of ASTRID were the multi-recycling of plutonium, aiming at preserving natural uranium resources, minor actinide transmutation, aiming at reducing nuclear waste, and an enhanced safety comparable to Generation III reactors, such as the EPR. It was envisaged as a 600 MW industrial prototype connected to the grid. A commercial series of 1500 MW SFR reactors was planned to be deployed around 2050.As of 2012, the project involved 500 people, with almost half among industrial partners. Those included Électricité de France, Areva, Alstom Power Systems, Comex Nucléaire, Jacobs France, Toshiba and Bouygues Construction.In 2014 Japan agreed to cooperate in developing the emergency reactor cooling system, and in a few other areas. As of 2016, France was seeking the full involvement of Japan in ASTRID development. In November 2018 France informed Japan it will halt joint development.In August 2019 France cancelled ASTRID and sodium-breeder in general, with an official statement that “In the current energy market situation, the perspective of industrial development of fourth-generation reactors is not planned before the second half of this century. About €735 million had been spent on the project.

Marcoule Nuclear Site (French: Site nucléaire de Marcoule) is a nuclear facility in the Chusclan and Codolet communes, near Bagnols-sur-Cèze in the Gard department of France, which is in the tourist, wine and agricultural Côtes-du-Rhône region. The plant is around 25 km north west of Avignon, on the banks of the Rhone. Operational since 1956, Marcoule is a gigantic site run by the atomic energy organization Commissariat à l'Énergie Atomique (CEA) and Areva NC and is known as CEA VALRHO Marcoule. The first industrial and military plutonium experiments took place in Marcoule. Diversification of the site was started in the 1970s with the creation of the Phénix prototype fast breeder reactor, which was operational until 2009, and is nowadays an important site for decommissioning nuclear facilities activities. As of 2016 the Phénix reactor was planned to be succeeded by the sodium-cooled fast reactor ASTRID (Advanced Sodium Technical Reactor for Industrial Demonstration), foreseen to become operational in the 2030s. However, in 2019 the ASTRID project was closed.Since 1995, the MELOX factory has been producing MOX from a mix of uranium and plutonium oxides. MOX is used to recycle plutonium from nuclear fuel; this plutonium comes from the COGEMA La Hague site. The ATelier Alpha et Laboratoires pour ANalyses, Transuraniens et Etudes de retraitement (ATALANTE) is a CEA laboratory investigating the issues of nuclear reprocessing of nuclear fuel and of radioactive waste.

Phénix (French for phoenix) was a small-scale (gross 264/net 233 MWe) prototype fast breeder reactor, located at the Marcoule nuclear site, near Orange, France. It was a pool-type liquid-metal fast breeder reactor cooled with liquid sodium. It generated 590 MW of thermal power, and had a breeding ratio of 1.16 (16% more plutonium produced than consumed), but normally had to be stopped for refueling operations every two months. Phénix continued operating after the closure of the subsequent full-scale prototype Superphénix in 1997. After 2004, its main use was investigation of transmutation of nuclear waste while also generating some electricity. Phénix was shut down in 2009.The decommissioning project started in 2005. Between 2009 and 2011, the non-nuclear equipment and turbine hall were dismantled. The decommissioning license was expected for 2015. Finalising of the decommissioning process is expected between 2031 and 2043.

The Aigues (French pronunciation: [ɛɡ]), Aigue, Aygues or Eygues is a French river, a tributary of the Rhône. It runs through the departments of Drôme, Hautes-Alpes and Vaucluse. Its source is in the Baronnies mountains. It flows through Verclause, Sahune, Nyons, and it flows into the Rhône at Caderousse. It is 113.7 km (70.6 mi) long. Its drainage basin is 1,012 km2 (391 sq mi).Several spellings of the name are in use: the French national map service Géoportail shows both "l'Aigues" and "l'Aygues" on maps of the same area near Orange, and the village name of Saint-Maurice-sur-Eygues preserves another variant. Among its tributaries is the Lauzon.
