Dismantling a nuclear power plant, illustration. First the fuel rods are removed from the reactor and transported by special ship to an interim storage facility to cool down for 40 years (left). The reactor vessel is then removed, enclosed in a radiation-safe concrete casing, and stored deep underground. In the third step (right), the rest of the power plant is dismantled. The radioactive parts are stored with the reactor core. This procedure is being followed in the dismantling of the two boiling water reactors at Barseback in southern Sweden, which shut down in 1999 and 2005.
