Stade Nuclear Power Plant
F1
Decommissioned Reactors ( gross ):
The nuclear power plant Stade ( KKS ) was operated from 1972 to 2003 in Stader sand near the rocker mouth of the Elbe. It is the first decommissioned after the nuclear phase-out nuclear power station and is currently under restoration ( Phase 4: Degradation of the remaining contaminated plants, proof of freedom from contamination, dismissal of the remaining structures from nuclear regulatory control ). The PPS is 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 also next to the disused and already decommissioned power plant Schilling. It was equipped with a leichtwassermoderierten pressurized water reactor.
History
In July 1967, the North West German power stations AG applied for the construction and operation of the nuclear power plant Stade. In October 1967, award of the contract to Siemens AG for the turnkey construction. November 1967 start of construction after the authorization for earthworks. March 1968 establishing the nuclear power plant Stade GmbH. June 1971 implementation of non- nuclear commissioning. January 1972 approval for nuclear commissioning.
The power plant was built by Siemens, the construction cost the equivalent of 150 million euros. It took on May 19, 1972 commercial operation after the first criticality was done on 8 January 1972. From March 1972 to the end of the power operation on 14 November 2003, the nuclear power plant generated a gross electrical output of 662 MW and 630 MW net electrical capacity of 1892 MW thermal power. On Friday 14 November 2003 at 8.31 clock the Stade nuclear power plant was officially shut down. The operator E.ON stated economic reasons for the shutdown.
By 7 September 2005, the power plant was in the night operation, then the rest of operation. A total of 157 fuel elements were used in the power plant, including fuel with up to 4% uranium -235 ( since 15 December 1988). Since 1984, the adjacent saline was powered by a steam extraction process steam. This was the first deployment of district heating by a nuclear power plant.
Dismantling
The decommissioning of the power plant is divided into 5 phases, to be completed by 2015; the operator E.ON earmarks 500 million euros (as of March 2011).
- Phase 1: Degradation no longer needed for the rest of the operating system installation parts, preparation of further dismantling steps, creation of necessary infrastructure
- Phase 2: reduction of the major components in the reactor containment vessel, in particular the four steam generators
- Phase 3: dismantling of the reactor pressure vessel ( with lid ), the core internals, the biological shield and other systems and components
- Phase 4: Degradation of the remaining contaminated plants, proof of freedom from contamination, dismissal of the remaining structures from nuclear regulatory control
- Phase 5: Conventional demolition of buildings
On 27 April 2005, the last fuel elements were delivered from the nuclear power plant. The Lower Saxony Ministry of Environment has approved a warehouse with a capacity of 4,000 cubic meters of low and intermediate level radioactive waste at the power plant up to 2046.
Consequences for the region
With the decommissioning of the nuclear power plant Stade also the operation of the adjacent saline was set, which had been previously obtained in the 20 years the hot steam from the power plant.
It is now scheduled to take the nuclear power plant to build a coal-fired power plant with about the same performance, for which the state of Lower Saxony but still would have to expand the port Stade- Bützfleth a coal feeder, where the annual 1.7 million tonnes of coal can be handled.
