The Stade nuclear power plant (PPS) between 1972 and 2003 Stadersand near the rocker mouth at the same run. It was the first nuclear power plant in Germany to be decommissioned after the nuclear phase-out and is currently in the process of being dismantled (phase 4: dismantling of the remaining contaminated parts of the plant, proof of freedom from contamination, releasing the remaining structures from monitoring under nuclear law). The KKS is located on the southern bank of the Lower Elbe in the district of the Hanseatic city of Stade in Lower Saxony , about 30 km west of Hamburg and next to the Schilling oil-powered power plant, which has also been closed and has already been dismantled . It was equipped with a light water moderated pressurized water reactor .

history

In July 1967, Nordwestdeutsche Kraftwerke AG applied for the construction and operation of the Stade nuclear power plant. In October 1967 the order was placed with Siemens AG for turnkey construction. November 1967 Start of construction after approval for earthworks has been granted. March 1968 Foundation of Kernkraftwerk Stade GmbH. June 1971 Implementation of the non-nuclear commissioning. January 1972 Approval for nuclear commissioning.

The power plant was built by Siemens or Kraftwerk Union , the construction cost the equivalent of 150 million euros. It went into commercial operation on May 19, 1972 after the first criticality had occurred on January 8, 1972. From March 1972 until the end of power operation on November 14, 2003, the nuclear power plant generated a gross electrical output of 662  MW or 630  MW electrical net output from 1892  MW of thermal output. On Friday, November 14, 2003 at 8.31 a.m., the Stade nuclear power plant was officially shut down. The operator E.ON gave economic reasons for the shutdown.

The power plant ran in post-operation until September 7, 2005 , then in residual operation . A total of 157 fuel elements were used in the power plant, including fuel elements with up to 4% uranium-235 (since December 15, 1988). From 1984 until it was closed, the neighboring saltworks was supplied with process steam via a steam extraction system.

architecture

The associated administration building was completed by the architect Gustav Burmester in 1971.

Data of the reactor block

The Stade nuclear power plant had one reactor block :

Dismantling

method

The dismantling of the power plant since October 2005 was divided into 5 phases, which should have been completed by 2015; the operator E.ON initially estimated 500 million euros for this in March 2011.

  • Phase 1: Dismantling of parts of the plant that are no longer required for the remaining operation of the plant, preparation of further deconstruction steps, creation of the necessary infrastructure
  • Phase 2: Dismantling the large components in the reactor containment, especially the four steam generators
  • Phase 3: Dismantling the reactor pressure vessel (with cover), the core internals, the biological shield and other systems and components
  • Phase 4: Dismantling of the remaining contaminated parts of the facility, proof of freedom from contamination, release of the remaining structures from monitoring under nuclear law
  • Phase 5: Conventional demolition of the building

As of March 2017, it is assumed that the dismantling will take until 2023. The dismantling costs at that time were put at one billion euros.

procedure

On April 27, 2005, the last fuel elements were removed from the nuclear power plant. The Lower Saxony Ministry of the Environment has approved a storage facility with a capacity of 4,000 cubic meters for low-level and medium-level radioactive waste on the power plant site until a maximum of 2046.

The dismantling was supposed to be completed by the end of 2014, but new problems emerged in the same year: radioactively contaminated condensation was detected in the base area of ​​the reactor building, which presumably came from leaks in the primary water circuit during operation. Values ​​of up to 164 Bq / g were measured in the floor area. The Ministry of the Environment in Hanover announced that dismantling might take three or four years longer.

In December 2016, the operator PreussenElektra estimated that around one billion euros would have to be spent on the dismantling. The dismantling should take until 2023 Template: future / in 3 years.

Consequences for the region

With the shutdown of the Stade nuclear power plant, the neighboring saltworks , which had drawn hot steam from the power plant for around 20 years , also stopped operating .

In the meantime, there were plans to replace the nuclear power plant, a coal-fired power plant with about the same power to build, for the country Lower Saxony still the seaport Stade would expand -Bützfleth a coal feeder, where the annual 1.7 million tons of coal handled can be.
