If today is 20 December 2019 at 12.30 PM NPP Ostermundigen is stopped, then this will not happen for security reasons, and for reasons political and economic. A few hours before deciding to shut off the operating company BKWВнешняя link sure that she had everything under control.
Dismantling a nuclear power plant (NPP)? In Switzerland so no one has ever encountered. However, the fear of a possible nuclear accident, and no one experiencing. No additional measures for the protection of the population was taken.
Not only the operating company, the BKW group, but also the state body for supervision in the field of nuclear energy, media, and even the most ardent opponents of the NPP Ostermundigen sure that everything goes according to plan, as always in Switzerland. How would it look? Details in our video:
Switzerland’s first NPP will be closed in the city of Ostermundigen near Bern. How will it look in practice?
And when it comes to the risks that refers to any financial costs, to be funded from the pockets of taxpayers and shareholders of the company-operator or possible bottlenecks in energy supply, or refers to the still unresolved problem of final disposal of plant elements and nuclear fuel. Let’s look at all the frequently asked questions:
Will there be a shortage of electricity?
The end settiamana power station Ostermundigen, located a few kilometers West of Berne, worked a total of 47 years. Per year on average, it produced about 3 000 gigawatt-hours of electricity, which corresponds to approximately 5% of the total domestic demand. To ensure a reliable mode of energy supply company BKW will be able after stopping the nuclear power plant to purchase additional electricity on the European market.
Today’s headlines Swiss newspaper is sustained in tones almost poetic: “the Death of Ostermundigen has an effect akin to doping”, “the team noticed …
Author: Christian Raaflaub (Christian Raaflaub)furthermore, since at present the conditions for increased domestic energy production through hydropower and wind power in Switzerland is not, BKW is investing heavily, primarily in wind farms in neighbouring countries, i.e. in Germany and in Scandinavia. These investments are also designed to prevent the occurrence of deficiency of energy in Switzerland
Is it true that a death sentence for nuclear power plants Ostermundigen was the accident at the nuclear power plant in Fukushima?
Citysquare the end, her sentence was signed by the Chernobyl disaster, after which the opponents of nuclear energy in Switzerland organized themselves and began to demand to stop one of the oldest in Switzerland NPP, i.e. reactor in Ostermundigen. Of course, after the disaster at the nuclear power plant complex in Fukushima this demand gained momentum, winning significant public support.
Ultimately, however, as the BKW group, the most significant were for economic reasons: to stop the antiquated station was cheaper than constantly patching it and brought in line with the latest regulations in the field of safety of nuclear energy.
What happens with the fuel rods?
The end cittapala team to stop the reactor will begin to “wind down”, as it has happened regularly during the annual technical audits. Dismantling of turbines, generators and condensers can be started immediately without delay.
Cover of the reactor vessel under pressure, remains closed for another three months. During this time the radioactivity will be reduced by about three orders of magnitude in comparison with the standard working mode.
After that, fuel cells will be extracted and placed in a separate special pool where they will be stored for several years until, until the level of radioactivity decreases even more. The dismantling of elements of the reactor building will be performed remotely, all the elements and technical units will be dealt with under the water to avoid contact with residual radiation in the atmosphere.
Why the dismantling of nuclear power plants will take as much as 15 years?
Cytotec the end of 2024, all fuel elements are moved to the Central interim storage high-level nuclear waste in Wuerenlingen (Wurenlingen) in the Canton of Aargau, which means, according to the company statement, that by the time the NPP will lose 98% of its radioactivity remains. Where in Switzerland will be built permanent (eternal) storage of spent nuclear fuel — that no one knows yet. One thing is clear: in Russia the Swiss fuel as it was before, no luck.
The objects and elements that make up the “nuclear part” of the station, eventually will be dismantled by 2030. For deep geological disposal will be a total of 6,000 tons of radioactive materials, equivalent to 2% of the total volume of all nuclear power plants. The remaining 98% used in the construction of nuclear power plant materials (approximately 200,000 tons) will be recycled or disposed of as construction debris.
Only in the period until 2030 on the dismantling of nuclear power plants will operate an average of about 200 people. In the period between 2030 and 2034 years of the building, which will no longer be necessary, will be permanently demolished. Starting in 2034, the platform on which once stood NPP will be ready for use for other purposes. The construction of a nuclear power plant in Ostermundigen in the 1960-ies took five years and a cost of 302 million Swiss francs. The withdrawal process of decommissioning, dismantling and disposal will take 15 years and will cost 2.1 billion Swiss francs.
