Canton of Châtenay-Malabry

The Arboretum de la Vallée-aux-Loups (13.5 hectares) is a notable arboretum located at 102 rue de Chateaubriand, near the Maison de Chateaubriand, in Châtenay-Malabry, Hauts-de-Seine, Île-de-France, France. It is open daily except Monday, but closed in January; an admission fee is charged. The park was created circa 1777 by the Chevalier François-Louis Durant du Bignon. It was confiscated during the French Revolution, changed hands several times, and then acquired in 1804 by Louis Cadet de Gassicourt, pharmacist to Napoleon, who collected and maintained rare plants on the property. (In 1807 an adjacent house was purchased by François-René de Chateaubriand, which he christened La Vallée aux Loups, "Valley of the Wolves", and where he subsequently dwelled with his wife until 1818.) The park was sold in 1890 to Louis-Gustave Croux who created today's arboretum. In 1986 it was sold once more to the Conseil Général des Hauts-de-Seine, its current owner. Today the garden is laid out as a landscaped park with a pond, island, and bridges, and contains about 2500 plants representing more than 500 woody species, including 165 species of trees. It is organized into a dozen gardens, including an English garden, fruit garden, chestnut garden, and Convolvulaceae collection. The hydrangea garden contains more than 300 cultivars, and is nationally designated one of the Conservatoire des Collections Végétales Spécialisées (CCVS).

Châtenay-Malabry (French pronunciation: [ʃatnɛ malabʁi] ) is a commune in the southwestern suburbs of Paris. It is located 10.8 km (6.7 mi) from the center of Paris. The French writer Chateaubriand lived in the estate Vallée-aux-Loups at Châtenay-Malabry. The Garden City in the Butte Rouge, the Cité Jardins, is one of the earliest examples of housing at moderated rents (HLM). Châtenay is the location of École Centrale Paris, of the Faculty of Pharmacy of the University of Paris-Sud and of French national laboratory of doping detection. It is also the home of the Arboretum de la Vallée-aux-Loups. The high-speed LGV Atlantique crosses the city through a tunnel covered by a park called Coulée verte (greenway). From 31 December 2002, it was part of the Agglomeration community of Hauts de Bièvre, which merged into the Métropole du Grand Paris in January 2016.

Le Plessis-Robinson (French pronunciation: [lə plɛsi ʁɔbɛ̃sɔ̃] (listen)) is a commune in the southwestern suburbs of Paris, France. It is located 10.5 km (6.5 mi) from the center of Paris. As of 2017, it has 29,100 inhabitants.

The Arboretum municipal de Verrières-le-Buisson (1.5 hectares), more formally the Arboretum municipal de Verrières-le-Buisson, Réserve naturelle volontaire Roger de Vilmorin, Maison des Arbres et des Oiseaux, is a municipal arboretum located at 1, voie de l'Aulne, Verrières-le-Buisson, Essonne, Île-de-France, France. It is open weekends without charge. The arboretum was established in 1910 as part of the Arboretum Vilmorin, acquired in 1975 by the municipality, and is now tended by young people 14–25 years in age. It contains more than 200 species of trees from the northern hemisphere, as well as several from the southern hemisphere. The arboretum is organized as a wooded area, orchard, prairie, pond, and nursery.

The Arboretum Vilmorin (4 hectares) is a private arboretum located at 2 rue d'Estienne d'Orves, Verrières-le-Buisson, Essonne, Île-de-France, France. It is open by appointment only. A newer portion of the family arboretum was acquired by the municipality in 1975, and is now open to the public as the Arboretum municipal de Verrières-le-Buisson. The arboretum is located on the site of a former hunting lodge of Louis XIV of France, acquired in 1815 by Philippe-André de Vilmorin (1776-1862), who also began today's Arboretum national des Barres in 1821. He transformed the lodge's grounds into a collection of trees and shrubs from around the world as missionaries and explorers sent specimens from the Far East, America, North Africa, Siberia, and the Caucasus. Plans for the arboretum walls are attributed to André Le Nôtre. Today's arboretum has been tended by seven generations of the Vilmorin family, assisted in recent years by a scientific committee. At present the arboretum contains some 2,280 identified species, with major collections of Acer, Berberis, Deutzia, Euonymus, Malus, Lonicera, Philadelphus, Quercus, and Rhododendron. Specimens of interest include Carya buckleyi, Cedrus libani, Chionanthus retusus, Halesia diptera, Juglans x intermedia, Parrotia persica, Pinus bungeana, Pseudolarix amabilis, Quercus persica, Sorbus torminalis, Taxodium ascendens, and Torreya grandis.

École Centrale Paris (ECP; also known as École Centrale or Centrale) was a French grande école in engineering and science. It was also known by its official name École Centrale des Arts et Manufactures. In 2015, École Centrale Paris merged with Supélec to form CentraleSupélec, a constituent college of the University of Paris-Saclay.Founded in 1829, it was among the most prestigious and selective grandes écoles. Rooted in rich entrepreneurial tradition since the industrial revolution era, it served as the cradle for top-level engineers and executives who continue to constitute a major part of the industry leadership in France. Since the 19th century, its model of education for training generalist engineers inspired the establishment of several engineering institutes around the world, such as the École Polytechnique Fédérale de Lausanne in Switzerland, Faculté polytechnique de Mons in Belgium, as well as other member schools of the Ecole Centrales Group alliance in France, Morocco, China, and India.

The Zoé reactor, or EL-1, was the first French atomic reactor. It was built in 1947 at the Fort de Châtillon in Fontenay-aux-Roses, a suburb of Paris. Design work for the heavy-water reactor was started in 1947 by Frédéric Joliot-Curie, who was at the time director of the French Commission for Atomic Energy (Commissariat à l'énergie atomique (CEA)). The project manager was Lew Kowarski, who had just returned from Canada, where he had supervised the construction of the Canadian ZEEP heavy-water reactor. Zoé was activated on 15 December 1948, reaching a power of 150 kW by 1953. The nuclear fuel was provided by Bouchet of Ballancourt-sur-Essonne, which reprocessed the irradiated fuel and extracted the first milligrams of French-produced plutonium. The reactor was shut down in March 1976 and containment of the reactor was completed in 1977. The choice of moderator and fuel was dictated by the undeveloped state of the French nuclear industry at the time, which could not manufacture the corrosion-proof equipment needed for a more advanced unit. The reactor was a pool-type design, with five tons of heavy water moderator surrounded by a two-meter-thick concrete wall. The core, immersed in the pool, consisted of 60 aluminum-cased vertical rods containing three tons of uranium oxide pellets, controlled by cadmium rods. The heavy water was purchased from Norsk Hydro. A cooling system was added after the reactor had operated for a time, allowing it to run at a heat release rate of 200 kilowatts.The name Zoé was an acronym, from Zéro de puissance (zero power, that is, very little capacity to produce electricity, which made it easier and faster to build); Oxyde d'uranium (uranium oxide), Eau lourde (heavy water). The Châtillon site was superseded for later nuclear research by a new site at Saclay. The reactor was also known as EL-1 (Eau Lourde); its successor at Saclay was EL-2.The building that formerly housed Zoé is now an exhibit space, the Museum of the Atom.
