The Obrigheim Nuclear Power Plant (KWO) is a mothballed nuclear power plant in Obrigheim, Neckar-Odenwald-Kreis, at the river Neckar. It operated one pressurized water reactor unit.
History 1959-2005

On May 5, 1955 the Federal Republic of Germany, with the French occupation force, started to work seriously towards peaceful use of nuclear energy. the district of Bavaria and Baden-Württemberg were particularly interested in this development. In 1957 the Arbeitsgemeinschaft Kernkraft Stuttgart (AKS) group had already been created in Baden-Württemberg. The president and minister of economics of Baden-Württemberg at the time, Hermann Veit took over the project of establishing a nuclear power plant, and looked towards the Calder Hall Gas cooled reactor in England for a design.[citation needed]
In the spring 1959, AKS chose an unusual reactor design, the organically moderated and cooled reactor (OMR). When the much smaller AEC demonstration facility at Piqua, Ohio reported severe problems, they switched to a light water reactor in 1962. [citation needed]
The reactor went online in 1969 and was shut down in 2005.[1]
Decomissioning, 2005-present
Since 2005 the EnBW power plant has been in the process of dismantlement; the spent fuel rods have been in wet storage since 2007. The salient barrier is a missing final repository for the 342 highly radioactive fuel rods. Obrigheim does not have an interim storage facility. For EnBW not to have to build one, the fuel rods need to be shipped to the nuclear power plant in Neckarwestheim, which still has space in its temporary storage. The move has already been approved, but it is still unclear by what means. EnBW has considered transport by road, by rail and by barge. The former 2 do not apply absent a nearby train connection, and road transport is complicated by single lane roads through a densely populated area, where large-scale barriers would have to be made.[1]
Since both nuclear plants were built on the banks of the Neckar, barge transport is the preferred way to go. The distance from Obrigheim to Neckarwestheim is about 40 kilometers and a ramp has already been built. To test the process, EnBW had shipped empty nuclear waste containers over the Neckar in early March 2017. Even the green environment ministry in Baden-Württemberg thinks the waterway is the best solution, but the Bundesministerium für Umwelt/ Federal Ministry of the Environment approval is yet to come. For the first time in Germany´s history, highly radioactive waste would be transported on a river.[1]
Protest against the castor transports on the river has been building. About 650 people followed a call for the "Neckar castorfrei" campaign to protest and march as "a sign before the anniversary of the Fukushima disaster of March 11, 2011".[1]
Power line
The electric power was transported by a single powerline to Hüffenhardt substation. The powerline carried 4 circuits, 2 for 220 kV and 2 for 110 kV. The circuits for 110 kV were mounted on the lowest of the three crossbars of the pylons, and the circuits for 220 kV on the middle and the upper crossbar of the pylons.[jargon]
An interesting feature of the powerline between the pylons is that insulators are mounted between the conductors to prevent short circuits by too close a conductor clearance with strong winds.[according to whom?]
Meteorological towers
For radioactivity monitoring there were two meteorological towers, which were both built as guyed lattice steel mast. One of them was built in 1977/78 between Asbach and Kirstätter Hof at 49 20 30 N and 9 02 47 E. In 2001 this 169 metres tall guyed mast was demolished by explosives. On its site afterwards a free-standing mobile phone transmission tower consisting of prefabricated concrete was built. The other meteorological tower erected in 1962 is 99 metres tall, located close to the power plant, and is still in use.[citation needed]
