Obrigheim Nuclear Power Plant
Template:Infobox NPP The shut down Nuclear power station Obrigheim (KWO) lies in Obrigheim in Neckar-Odenwald-Kreis (a part of Neckar). It operated one pressurized water reactor unit.
History
Planning
On May 5, 1955 the Federal Republic of Germany, with the French occupation force, started to work seriously towards peaceful use of nuclear energy. Particularly the district of Bavaria and Baden-Württemberg were interested in such development. In 1957 the Arbeitsgemeinschaft Kernkraft Stuttgart (AKS) group had already been created in Baden-Württemberg. The president and minister of economics of Baden-Wuerttenberg at the time, Hermann Veit took over the project of establishing a nuclear power plant, and looked towards the Calder Gas cooled reactor in England for a design.
In spring 1959, AKS chose an exotic 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.
Power line to the plant
The electric power generated by Obrigheim Nuclear Power Station was transported by a single powerline to Hüffenhardt substation. This powerline carries 4 circuits, 2 for 220 kV and 2 for 110 V. Hereby the circuits for 110 kV are mounted on the lowest of the three crossbars of the pylons, whereby the circuits for 220 kV are mounted on the middle and the upper crossbar of the pylons.
An interesting feature of the powerline is, that between the pylons insulators are monted between the conductors in order to prevent short circuits by too close conductor clearance when strong wind occurs.
Meteorological towers
For radioactivity monitoring there were two meteorological towers, which were both built as guyed lattice steel mast. One of them was 169 metres tall and situated at 49 20 30 N and 9 02 47 E between Asbach and Kirstätter Hof. It is now dismantled and replaced by a free-standing mobile phone transmission tower consisting of prefabricated concrete. The other meteorological tower, which is 99 metres tall and situated close to the power plant, is still in use.
