Isar 2 nuclear power plant closed for a short period


The Isar 2 nuclear power plant between Landshut and Dingolfing was closed short-term on Sunday due to an outage. The reason is a leak in a control valve in the water supply system of the secondary water-steam cycle, explains operator PreussenElektra.

The escaping water vapor contains no radioactivity. For industrial and technical safety reasons, the leak can be made when the system is depressurized, announced PreussenElektra. The length of time the Isar 2 will remain off can only be estimated after the location of the leak has been inspected and repairs determined. This will happen sometime on Monday today.

The leak was discovered during a routine visit to the facility, reports the Bavarian Broadcasting Corporation. Water is currently drained into the affected area and the system is cooled. The power supply is guaranteed despite the disturbance, and appropriate arrangements are made for such cases. There is no danger for the population.

The pressurized water reactor of the Konvoi Isar 2 construction line with 193 fuel elements is one of three reactors still in operation in Germany; according to the atomic energy law amended in 2011, it will have to be withdrawn from the grid with the nuclear power stations of Neckarwestheim 2 and Emsland by the end of this year at the latest. Boiling water reactor block 1 was shut down along with seven other reactors in 2011; it has been dismantled since April 2017.

Unit C at the Gundremmingen nuclear power plant in Bavaria has been in service since March 1984. Block A operated from 1967 to 1977. Unit B, commissioned in 1984, was closed on December 31, 2017, unit C – also commissioned in 1984 – monitoring end of 2021. (Image:

Isar 1 was connected to the grid in 1979, Isar 2 with its thermal power of 3,950 MW and electrical power of 1,485 MW followed on April 9, 1988, and since then, according to PreussenElektra, it has been a ten-time production world champion. annual electricity. The last revision of the Isar 2 for the last 14 month production run took place from the end of September to October 14 of last year. The reactor was equipped with 48 new fuel elements.
