The compact sodium-cooled nuclear reactor facility in Karlsruhe (abbr. KNK ) was a breeder reactor on the premises of the Karlsruhe Research Center with a gross electrical output of 21 MW.
history
In 1971 the power plant was commissioned as a so-called thermal reactor and was in operation until 1974. This system was designated as KNK-I. The plant was then converted into a prototype of a fast breeder reactor power plant based on the basic model of the Russian BOR-60 and then referred to as KNK-II. This went into operation in 1977 and was finally shut down on August 23, 1991. The reactor served as a test facility for the Kalkar nuclear power plant , a project that ended in the same year.
Decommissioning and dismantling
The dismantling work for the total removal of the facility has been underway since 1993, and was originally planned to be completed by 2019 (“green field” status). In December 2019, however, according to the website of the commissioned company KTE , the last step was missing , the dismantling of the biological shield with a remote-controlled excavator. According to statements from the Federal Ministry of Research, the disposal of the reactor will cost 309 million euros, 100 million euros more than planned. The reason for this is, among other things, technical problems when removing the reactor tank.
Nuclear fuel
The spent fuel was transported to Cadarache between 1989 and 1994 , where it was reprocessed. The fuel rods were placed in containers of the Castor KNK type .
