When it came into operation fifty years ago, the Beznau I power station marked the beginning of the commercial exploitation of atomic energy in Switzerland. Today, it is one of the oldest thermonuclear power plants in the world still in use. Only a few plants in India and the United States are a little older than the reactor built in the middle of an Aare islet, next to his brother Beznau II: the official start of its commercial exploitation dates back to 9 December 1969 . At the time, Switzerland had abandoned its attempts to build its own reactor: the serious accident of the Lucens reactor in January of the same year had definitely buried the dreams of self-sufficiency of the country in nuclear matters. The commissioning of the Beznau I reactor, produced in the United States, has opened a new chapter in Swiss energy policy. In the space of 15 years, with the construction of the Beznau II (1972), Mühleberg (1972), Gösgen (1979) and Leibstadt (1984) plants, nuclear energy eventually covered 40% of the country’s energy needs.
