The Karlstein research reactor is the name given to two research reactors that were operated in the 1960s and 1970s first by AEG and later by Kraftwerk Union in Karlstein am Main .

history

The RWE started together with Bayernwerk in 1958 in Großwelzheim (today Karl Stein), the construction of the nuclear power station Kahl , Germany's first nuclear power plant . The AEG decided to promote the independent development of its boiling water reactor , then to build its own nuclear energy test facility. The AEG research institute in Frankfurt-Niederrad was originally intended to be the site of the plant , but no permit was obtained there for the construction of a nuclear reactor . For example, a site near the Kahl nuclear power plant, which is still under construction, was sought and finally acquired by RWE.

Construction of the "Großwelzheim nuclear energy test facility" began in January 1960. The establishment of the nuclear energy test facility - just like the nuclear power plant - met with great approval from the citizens of Großwelzheim at the time. The municipality even included the atomic symbol in its coat of arms in 1965. After the merger of Großwelzheim with Dettingen in 1975 to form the new municipality of Karlstein am Main , the symbol can also be found in the new coat of arms.

The two research reactors PR-10 and TKA were built at the site and maintained for a total of 15 years. In addition to the two research reactors, AEG also operated the Großwelzheim experimental nuclear power plant there in the early 1970s .

On April 1, 1973, Siemens and AEG merged their reactor development and research departments and incorporated them into the joint venture Kraftwerk Union, founded in 1969 . The AEG nuclear energy test facility thus became the development, service and training center of Kraftwerk Union. The location has belonged to AREVA since the beginning of 2001 .

Reactors

AEG test reactor

The AEG test reactor (PR-10) was an Argonaut reactor that was in operation from January 27, 1961 to 1976. The reactor was moderated with light water, the neutron reflectors were made of graphite . The fuel elements made of highly enriched uranium were plate-shaped and coated with aluminum . The reactor had a nominal output of initially 10, later 180  watts . The maximum thermal neutron flux density was 2.5 × 10 ¹⁰ n / (cm ² s). The decommissioning of the reactor began on July 27, 1976 and was completed on February 22, 1978.

AEG zero energy reactor

The AEG Zero Energy Reactor (TKA) was a tank-type zero power reactor that was in operation from June 23, 1967 to 1973. It had an output of 100 watts and the neutron flux density was less than 10 ⁸ n / (cm ² s). Its decommissioning began on September 28, 1981 and was completed on December 21, 1981.
