Sellafield Vitrification should ensure safe storage of waste in the UK for the middle to long term. Construction of the Sellafield MOX Plant (SMP) was completed in 1997, though justification for the operation of the plant was not achieved until October 2001. Mixed oxide, or MOX fuel, is a blend of plutonium and natural uranium or depleted uranium which behaves similarly (though not identically) to the enriched uranium feed for which most nuclear reactors were designed. MOX fuel is an alternative to low enriched uranium (LEU) fuel used in the light water reactors which predominate in nuclear power generation. MOX also
Greifswald Nuclear Power Plant Greifswald Nuclear Power Plant Greifswald nuclear power station (German: "Kernkraftwerk Greifswald", KKW Greifswald), also known as Lubmin nuclear power station, 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 second generation of Soviet-designed plants. The plant is in Lubmin near Greifswald, in the state of Mecklenburg-Vorpommern. In late 1989, nuclear regulatory bodies of countries operating VVER plants found the need to fit many new safety systems, which were stated to have been necessary in almost all areas. All East German reactors were closed
