Zwentendorf Nuclear Power Plant

The Zwentendorf Nuclear Power Plant was the first commercial nuclear plant for electric power generation built in Austria, of three nuclear plants originally envisioned. Construction of the plant at Zwentendorf was finished but the plant never entered service. The start-up of the Zwentendorf plant, as well as the construction of the other two plants, was prevented by a referendum on 5 November 1978, in which a narrow majority of 50.47% voted against the start-up. Construction of the plant began in April 1972, as a boiling-water reactor rated at 692 megawatts electric power output. It was built by a joint venture of several Austrian electric power companies. The initial cost of the plant was around 5.2 billion Austrian schilling, approximately 1.4 billion euros adjusted for inflation. The ventilation stack chimney of the plant is 110 metres tall. Since the plebiscite, the plant has been partially deconstructed. The Dürnrohr Power Station was built nearby as a replacement thermal power station. Following the 1978 referendum, no commercial nuclear power plant (built for the purpose of producing electricity) ever went into operation in Austria. In 1978, Austria enacted a law prohibiting the construction and operation of fission reactors for electrical power generation, hence the plant nowadays is used for research purposes. Three small nuclear reactors for scientific purposes were
