The Nuclear power station Greifswald (German: Kernkraftwerk Greifswald, KGR), also known as nuclear power station Lubmin, was the largest nuclear power station in East Germany before closure shortly after the German reunification. The plants were of the VVER-440/V-230 type, which was the first generation of Soviet Union designed plants. The site is located in Greifswald in the state of Mecklenburg-Vorpommern.

In the late 1989 nuclear regulatory bodies of countries operating VVER plants did a safety analysis and produced numerous requirements for backfitting old safety systems, which were stated to have been necessary in almost all areas.[1] All reactors were closed soon after the reunification, with restart conditional on conforming to stricter and very different West Germany safety standards. There was a public discussion about the safety of the power station.
Convinced that backfitting to the new safety standards was not economically feasible, the new unified German government decided in early 1991 to decommission the four units, close Unit 5, which was undergoing testing at the time, and halt construction of the rest of the units there plus two VVER-1000s at the Stendal Nuclear Power Plant.[2]
The district heating from the plant was made up by oil imports and in 1995 by a new natural gas plant. Decommissioning of units 1 through 5 began in 1995, making Greifswald one of the first nuclear power stations in Germany to go through the process.
The plant came into focus again in 1996 when it was decided to move 235 unspent fuel assemblies to the Hungarian Paks Nuclear Power Plant, which could be done since it is of the same design.
At the peak of the plants operation, about 10,000 people were employed full time there. Currently, there are still about 1,000 working on decommissioning and other activities at the site.
