List of nuclear reactors in Austria

Ballot for the commissioning of the Zwentendorf nuclear power plant

The list of nuclear reactors in Austria includes all nuclear power plants and all research reactors. Nuclear reactors have been in operation in Austria since 1960. The nuclear power plants, however, never went into operation, and in two cases their planning and construction were also abandoned.

Austria was prohibited from any activity in the field of nuclear energy until the State Treaty of 1955 . In 1956, the Federal Government founded the “Austrian Study Society for Nuclear Energy GmbH” and commissioned the construction of a “power reactor as a learning model”. With the support of the US Nuclear Energy Commission , the nuclear reactor center near Seibersdorf, southeast of Vienna, was built by 1960 .

From 1972 to 1977 the Zwentendorf nuclear power plant was built with a planned output of 730 MW. The energy plan of 1976 provided for the construction of a total of three nuclear power plants with an output of 3,300 MW in Austria. The second nuclear power plant was planned for St. Pantaleon-Erla in Lower Austria. St. Andrä in Carinthia was planned as the location of the third power plant .

A referendum held on November 5, 1978 , with a wafer-thin majority of 50.47% against operations, prevented the already completed Zwentendorf nuclear power plant from going into operation.

Since December 5th, 1978 the Atomic Lockdown Act excluded the use of nuclear energy in Austria. Subsequent efforts to commission Zwentendorf were discontinued after the Chernobyl reactor disaster (April 26, 1986); In 1999 the Atomic Lockdown Act was raised to constitutional status. Since then it has been called the Federal Constitutional Law for a Nuclear-Free Austria .

Nuclear power plants without starting operations

Performance data

The grouping of nuclear power plants without starting operations includes all power reactors and prototype systems that were to be used for commercial electricity generation but have not yet been completed or whose planning and construction have finally been discontinued, as well as all power reactors that are not yet under construction but are firmly planned .

Research reactors

The research reactor grouping includes nuclear reactors that are not used to generate electricity, but are primarily used for research purposes (nuclear and material research, isotope production for medicine and technology ). The TRIGA reactor in Vienna is the only still in operation nuclear reactor in Austria today.
