- Very-low activity (TFA): 30% of total volume, negligible activity, they are stored in soft containers. - Low- and medium-activity, short-life (FMA-VC): 60% of total volume. They are compacted and poured in concrete, then stored. - Low-actiity, long-life (FA-VL): 6% of total volume, disposal method is under study. The two categories below represent >99% of total radioactivity: - Medium-activity, long-life (MA-VL) 3% of total volume, they are compacted. - High-activity, long-life (HA-VL): 0.2% of total volume, they are vitrified. MA-VL and HA-VL are then stored in stainless steel caskets, to be disposed in deep, geologically stable repositories (Cigéo in France, Onkalo in Finland, ...).
