Since we often in Lubmin, that lies on the Greifswalder Bodden, We had already planned to go on vacation to visit the Greifswald nuclear power plant. Once we were standing in front of the visitor's entrance. However, you have to register in advance and then you will be informed of the viewing date.
We did it that way, that we have given the period of our vacation by email. Within a few days we received the answer with the viewing appointment.
The Greifswald nuclear power plant is located between Lubmin and Freest. From Lubmin it is really only a short hop. We left right after breakfast on the day of the visit.
The dismantling of the nuclear power plant
The former Greifwald nuclear power plant has been virtually dismantled since German reunification. The EWN Entsorgungswerk für Nuklearanlagen GmbH is responsible for this. It operates the dismantling and disposal of the radioactive contaminated system components.
The larger, only slightly contaminated system parts, like big valves etc. are temporarily stored in specially shielded buildings. Fuel assemblies, Control rods and parts of the reactor are transported to the repository by castor transport. The employee of the company. EWN said in his lecture, that it will take decades, until the nuclear power plant will be completely dismantled.
The block open for inspection 6 of the former Greifswald nuclear power plant 1990 shortly before completion. After the turnaround and German reunification it was decided, shut down the entire facility. That's why the block 6 never loaded with nuclear fuel.
The entire tour lasted approx. 2h. At the beginning there is a ca. 30 minute presentation about the history of the Greifswald nuclear power plant. In addition, basic knowledge about the civilian use of nuclear energy is obtained. Of course, the risks are also discussed, that can occur during the operation of such a power plant.

If you stand outside in front of the system, the whole thing looks like a huge block of concrete. When entering the power plant block, the thickness of the outer wall is immediately apparent, we estimate that it is at least one meter thick. In general, the amounts of material used are like steel, Concrete and copper cables enormous.
As our guide told us, the nuclear reactor is a pressurized water reactor, where the cooling circuit with approx. 300 bar is under pressure. One of the advantages is that, that if a technical defect occurs, the reactor still up to 7 h is cooled passively. This is also the difference to the disaster reactor in Fukushima, which was a boiling water reactor, which can no longer be cooled by circulating pumps without an active cooling circuit. Which then led to the accident with the known consequences.
For those interested in technology there is a visit to the block 6 of the former Greifswald nuclear power plant is definitely worthwhile. Therefore recommendable. Please pay attention to our notice regarding the pre-registration.
