According to current legislation, Doel 3 is the first nuclear power station which will finally stop producing electricity, specifically in 2022. Tihange 2 will follow in 2023.
After the cessation of electricity production, first the final decommissioning phase will follow. All fuel is removed from the power stations, the radioactive systems are decontaminated, and after cooling, the used fuel which comes from the reactor is stored in specially protected containers, in specially designed docks with water. This phase lasts about 3 to 5 years, depending on the unit. Only after this does the actual dismantling follow. It is estimated to take 15 years, from the dismantling of the installations and the removal of all components from the installations until the decontamination of the radioactive areas to release the buildings and the site.
Nuclear dismantling means that the area in which the nuclear power stations are located is fully released and can be used for a different industrial purpose.
