Licensees responsible for nuclear waste management

Nuclear waste management means all measures necessary to recover, store, handle and permanently dispose of nuclear waste, including measures associated with the decommissioning of a nuclear facility.

An operator holding a licence to run a nuclear facility is responsible for the management of nuclear waste and all the related costs. To guarantee that outstanding nuclear waste management interventions can be carried out in all circumstances, licensees under a waste management obligation make payments to the Nuclear Waste Management Fund, as necessary.

The licence holders’ nuclear waste management plans are approved by the Ministry of Economic Affairs and Employment. The Radiation and Nuclear Safety Authority (STUK) monitors the implementation of the plans.

Disposal facilities for operational waste

There are underground final disposal facilities for low and intermediate level waste at the plant sites in Loviisa and Olkiluoto. The sites also include intermediate storages for spent nuclear fuel. At a later date, the spent fuel is transferred from these storages to Posiva Oy’s final disposal facility in Olkiluoto. The repository should be functional in around 2023. The construction licence was granted by the Government on 12 November 2015.

Fennovoima must further specify its plans for nuclear waste management. In terms of spent nuclear fuel, Fennovoima must either make an agreement on nuclear waste management cooperation with Posiva Oy’s owners or present an environmental impact assessment programme for its own final disposal facility.
