Decommissioning Fund

The Decommissioning Fund must cover the costs of decommissioning and dismantling nuclear power plants at the end of their useful life, together with the costs of disposal of the waste generated by those operations. The fund was set up in 1984.

The owners of the Beznau 1 and 2, Mühleberg, Gösgen und Leibstadt nuclear power plants as well as the central intermediate radioactive waste repository in Würenlingen are required to pay contributions.

The latest calculations suggest that the decommissioning costs for the five Swiss nuclear power plants and the central intermediate repository in Würenlingen will amount to around 3.8 billion francs (price basis 2016).

Cost study 2016 – The costs are reviewed every five years
The cost study 2016 was drawn up in the years 2015 and 2016. The independent review of the study was performed by ENSI and international experts in 2017. By comparison with the 2011 cost study, the costs have been reorganised and restructured. The process for review of the cost study has also been redefined: control and coordination of the cost study review have been entrusted to the Administrative Commission of the Decommissioning and Waste Disposal Fund.

At the end of 2017, the Administrative Commission submited a proposal to the Federal Department of the Environment, Transport, Energy and Communications (DETEC) with a view to determination of the decommissioning and waste disposal costs. The annual contributions of the operators to the two funds will be assessed on the basis of the decision taken by DETEC.
