Interim Storage

After it has been “burnt” in a nuclear reactor to generate electricity, spent nuclear fuel is interim stored pending final disposal (or reprocessing).

How is spent nuclear fuel stored?

What happens in the UK?

Currently, the UK operates an open fuel cycle for its generating nuclear power stations (the AGR and PWR reactors). At the moment, used fuel (known as spent fuel) is being interim stored – either on the same site as the power station or at the Sellafield site in Cumbria. Eventually, England and Wales plan to permanently dispose of all High Level Waste (HLW), including spent fuel, in a Geological Disposal Facility (GDF) – once this has been developed by Nuclear Waste Services.
