The plant was built to produce 692 megawatts of electricity before the 1978 referendum stopped it.
Over 1,000 employees worked on the construction of the plant before it was mothballed.
The facility is powered by a large-scale photovoltaic system installed on its exterior walls and grounds.
It is frequently used as a backdrop for high-budget film productions and television series.
The plant remains largely in its original 1970s configuration, including analog control panels and safety systems.
Despite never operating, the plant required constant maintenance to remain safe and functional for tours.
It has become a global destination for 'lost-place' photographers and industrial heritage enthusiasts.
The site includes a training center for safety and fire protection professionals.
AKW Zwentendorf is the world's only fully built nuclear power plant that never went into operation. Construction concluded in 1978, but a national referendum resulted in a permanent ban on nuclear energy in Austria. The facility is currently owned by EVN AG and serves as a training center, film set, and site for industrial events. Visitors can explore the reactor building, turbine hall, and cooling towers. The site is a primary example of industrial architecture preserved in a state of suspended animation. It functions as a unique time capsule of 1970s nuclear engineering technology.

Book guided tours well in advance as the facility is not open for independent exploration.
Dress in layers, as the massive concrete structures can be significantly cooler than the outdoor temperature.
Wear comfortable, closed-toe walking shoes as the tour covers extensive industrial terrain and staircases.
Do not attempt to arrive without a pre-booked guided tour, as site access is strictly controlled for security reasons.
Tours are available by appointment only; the site is occasionally closed for private industrial events or film shoots.
Strict safety protocols apply; visitors must wear provided safety gear in certain zones and stay with the guide at all times.
