Rheinsberg Nuclear Power Plant

Decommissioned Reactors ( gross ):

The nuclear power plant Rheinberg (KKR ) was the first commercially used nuclear power plant in the GDR. It was built in 1960 near the town of Rheinberg on an isthmus between the Nehmitzsee and the Great Stechlinsee, was commissioned in 1966 and was decommissioned in 1990. Since 1995 it is located in the demolition.

Historical classification

The power plant was the world's first generation of research and testing power plants for electricity generation. It was also used in the first exported by the Soviet Union nuclear reactor.

The Rheinberger reactor was the third nuclear reactor in the GDR. Previously, the Forschungszentrum Dresden -Rossendorf had taken two research reactors in operation.

The original plan envisaged a second reactor block and an attached factory for fuel assemblies. Among other things, the increase in construction costs of the planned 90 million Deutsche Mark Fed has (MDN ) to 400 million marks prevents the plans.

2012, the history of the nuclear power plant Rheinberg has been scientifically studied. A study to be published in January 2013 and opened an exhibition in Rheinberg.

Commissioning

First reflections on the project, which initially has the designation "Contract 903 " bore and were drawn for the nine possible locations into consideration, it was already 1955. The project was approved in 1956. Construction began on 1 January 1960 and the reactor was on March 11, 1966 for the first time critical ( still open reactor). The commissioning ceremony took place on May 9, 1966. The commercial continuous operation began on 11 October 1966.

Alternative location

As an alternative location of the nuclear power plant in the surroundings of the lake was considered. The better ground conditions and the low colonization were the deciding factors for the site in Rheinberg.

Accompanying construction

From the Rhine Bergbahnhof a ten kilometer long railway siding with a breakpoint in berry bush was built for the power plant. On 19 May 1958, the regular train operation began.

For the approximately 650 workers in the nuclear power plant, a new settlement was built.

Operation

The KKR was equipped with a pressurized water reactor of Soviet design VVER -210. The gross electrical power of this reactor was 70 MW. The net electrical capacity was 62 MW, thermal power 265 MW. Since 1 September 1967, the reactor was in trial operation at 75 MW, and soon after this performance was achieved in continuous operation. In October 1968 a trial basis, the electrical power was increased to 80 MW and then run from 25 November 1968, the power plant in continuous operation with 80 MW. The first transshipment of fuel assemblies took place in late 1967 to early 1968.

The cooling water was removed from the Nehmitzsee and introduced through the outlet channel of the nuclear power plant in the Stechlinsee. Both lakes are connected by the Polzowkanal, so that a cycle was.

The heaviest announced incident in Rheinberg (INES Level 2) was a crack pipe in the cooling circuit, which was noticed quickly and was able to be repaired.

It was planned an operation time of 20 years. In 1986 it was extended after renovations to five years. The " turn" led to a shortening of the operating time of approximately two years.

Decommissioning and Dismantling

Overall, the nuclear power plant made ​​130,000 hours of operation.

Shortly before the German reunification, the nuclear power plant was commissioned on 1 June 1990 due to significant security concerns from service. The regular shutdown had been planned for 1992.

Since 1995, the energy Nord GmbH operate the decommissioning of the power plant. The radioactively radiating materials are transported to the Interim Storage North at Greifswald nuclear power plant near Lubmin.

One of the required Castor transports served in 2001 as a backdrop for the movie " Fear" from the series " Police 110 " of the ORB.

On 30 October 2007, the entire reactor pressure vessel including the 15 -cm-thick shield weighed 169 tons, transported with the help of a 24 -axle heavy-duty transport vehicle in the Interim Storage North. It had then locked on the rail line Herzberg Rheinberg two dilapidated, making it particularly secure bridges in Lindow (Mark) to be crossed at a walking pace.

It is unclear the reuse of lying in the middle of a nature reserve area. Both the complete dismantling of the " green field" as well as an industrial re-use of existing infrastructure should be considered. The original plans have assumed that the state of a "green field ", the complete elimination of the plant is reached in 2012. However, the reactor building is heavily contaminated with Cobalt 60 and is expected only after 30 years ( the multiple half-life, less than 2% residual ) when the radiation levels have subsided, a reuse available or can only be demolished.

According to current (November 2011 ) the main dismantling and decommissioning works should be completed by 2014 at the NPP, the building decontamination should last until 2018. The 2019 beginning, fifty years Verwahrzeit to be completed in the year 2069, after which the main building can be demolished. The estimate of the total cost of the NPP decommissioning currently stand at 600 million euros, after they had been in 1995 initially stated, by 420 million euros.

In the area of ​​nuclear power plant groundwater is radioactively contaminated. In stock for low-and intermediate -level radioactive waste, which was simply built of concrete occurred in the seventies for cracks, could escape through the contaminated water. The camp was also dismantled under the NPP decommissioning and removed the material.
