The owners of Swiss nuclear facilities are legally obliged to dismantle their facilities after decommissioning and to dispose of all radioactive waste safely. They bear all costs associated with decommissioning and disposal. Decommissioning includes all activities until the nuclear facilities are released from the Nuclear Energy Act (KEG). The disposal obligation ends when the waste has been emplaced in the deep geological repository and the financial resources for the subsequent monitoring phase and any closure of the repository have been secured.
