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).

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.

The Fort de Châtillon was a fortification located about 5 kilometres (3.1 mi) south of Paris in the communes of Châtillon-sous-Bagneux and Fontenay-aux-Roses. It was built in 1874 and was razed beginning in 1957, making way for expansion of the French nuclear research facility at Fontenay-aux-Roses. The fort was named for the town it was designed to protect, Châtillon-sous-Bagneux, but the greater portion of the site is actually within Fontenay-aux-Roses. The main entry and the portions in Châtillon were destroyed at the end of the Second World War.
