The UK has a large variety of different intermediate- and high-level radioactive wastes, coming from national programmes to develop nuclear weapons and nuclear power. It is a national responsibility to pay for the management of these. In addition, new nuclear power stations could be built, the waste management from which would be the private sector's financial responsibility, although all would be stored in a single facility. Most of the UK's higher-activity radioactive waste is currently held in temporary storage at Sellafield. As of 2019 the 60-years long nuclear programme produced 2,150 m3 of high-level waste.
