The Niederaichbach nuclear power plant ( KKN , not to be confused with the also abbreviated, unrealized Niederamt nuclear power plant in Switzerland) was a pressure tube reactor and was located in the area of ​​the Niederaichbach community near Landshut (Lower Bavaria). The power plant was in operation from 1973 to 1974.

Technical data and operation

The gross electrical output of the nuclear power plant was 106  MW , the net electrical output was 100 MW.

The pressure tube reactor planned as a test power plant should enable operation with non-enriched uranium (natural uranium ). It was cooled with carbon dioxide (CO 2 ) and moderated with heavy water (D 2 O).

Construction of the nuclear power plant began in 1966. Although it was already foreseeable a year later that the concept of the heavy water reactor had relevant disadvantages compared to the light water reactor , the reactor was nevertheless completed. The construction costs were 230 million DM.

A year and a half after commissioning, the reactor had to be taken off the grid again in 1974 due to technical problems with the steam generators. The energy provided during this time only corresponded to around 18 days of full load. After the Niederaichbach reactor was shut down, the heavy water reactor line in Germany was no longer continued.

Dismantling the reactor

The reactor was first transferred to a safe enclosure , the fuel elements were transported to the CEA (Cadarache, France) for reprocessing.

1987 to 1995 the dismantling and removal took place; this was the first complete dismantling of a nuclear power plant in Europe to the point of "green field". It cost 280 million marks (corresponds to 201 million euros today). The activated steel parts of the plant were first transferred to the Karlsruhe Nuclear Research Center and in February 2011 to the interim storage facility in the north near Lubmin. From January 1995, waste was stored in the ERAM repository (Morsleben).

The site is currently part of the Isar nuclear power plant , which was built later. A memorial plaque has been installed on the site of the former nuclear power plant.
