Each year, nuclear power generation facilities worldwide produce about 200,000 m 3 of low-and intermediate-level radioactive waste, and about 10,000 m 3 of high-level waste including used fuel designated as waste.he most radioactive form of waste is categorized as high-level waste and whilst accounting for only 3% of the volume of all the radioactive waste produced (equating to around 25 cm 3 per UK citizen per year), it contains 95% of the radioactivity.
