Basic Information
The plant's reactor is of the pressurized water reactor type, using four water based coolant cycles, kept under high pressure. The design used for the plant's reactor is the Vor-Konvoi design, which was developed by Kraftwerk Union and used in several other power plants, such as the Brokdorf, Grafenrheinfeld and Philippsburg-2 power plants in Germany, as well as the Angra-2 power plant in Brazil.
The reactor used 193 fuel assemblies and utilized both enriched uranium and MOX fuel. In 1985, 1986, 1987, 1989, 1990 and 1998 the reactor produced more net electricity for the respective year than any other nuclear reactor in the world.

History
Construction of the plant began in 1975. The plant was built by PreussenElektra and Gemeinschaftskraftwerk Weser GmbH, with each company having a 50% share in the project.
Construction was completed in 1984 and the reactor reached first criticality the same year. Commercial electricity generation began on February 1st, 1985.
In 2003, ownership of the plant was transferred to E.ON Energie AG and Stadtwerke Bielefeld.
In 2021 the plant exceeded 400 TWh of total low-carbon electricity output since it was connected to the grid. As such, during its period of operation, the plant has prevented 400 million tons of CO2 emissions.[1]
The plant ceased power operation on 31 December 2021 as part of Germany's phaseout of nuclear power.[2]
The plant is currently undergoing decommissioning, which is expected to be completed around 2036.[2]
