First Nuclear Power to a Grid

ob-NEENSK
Mid-Century Power Transformations

On 26 June 1954 the reactor at Obninsk, southwest of Moscow, delivered electricity to a public grid, the first nuclear power station in the world. Its output was small, about five megawatts, but it opened the era of civilian nuclear energy, followed by Calder Hall in England in 1956 and Shippingport in the United States in 1957.
