On 16 June 2017, the Entsorgungsfondsgesetz (German Act on the Nuclear Waste Management Fund) came into force, establishing the Nuclear Waste Management Fund. On 3 July 2017, the operators of the 25 German nuclear power plants met their legal obligation to pay a total of EUR 24.1 billion into the foundation’s accounts. This is intended to secure the funding of the interim and final storage of radioactive waste. KENFO is the largest foundation under public law in Germany. It was formed with a one-off payment and the Entsorgungsfondsgesetz does not provide for any further additions to the fund’s assets, it is a limited-term endowment. The federal government is currently being reimbursed a three-digit million amount annually for the costs of safe interim and final storage.
