Radioactive waste is transported by road to Vaalputs in metal containers and concrete containers. Transportation is carried out in terms of the safety and security measures prescribed by the International Atomic Energy Agency (IAEA) transport regulations. Transport vehicles are subject to constant surveillance by means of satellite tracking systems and need to adhere to strict transportation schedules.
At Vaalputs, the drums are carefully inspected and monitored for conformance, before being packed, by type, into 8m deep trenches. Within two months, the drums are covered with a layer of soil from the area followed by a layer of compacted clay. Once the trench is full, a further half meter of soil is overlaid so that the natural vegetation can once again establish itself.
