New buildings – including a £10m store – could be located on the Sizewell A site on the north Suffolk coast to help deal with the power station's legacy of radioactive waste.

The Nuclear Decommissioning Authority (NDA) has begun a public consultation over the options for processing and storing 'intermediate level' waste created during the station's 40 years of operation, which ended in 2006. The option most likely to be adopted is the creation of a plant which uses acid to part-dissolve debris from the station's uranium fuel elements and the building of a store capable of holding the residue from this process and tonnes of other radioactive waste. However, the options also include the transport of fuel element debris to another power station site or the use of the Sizewell site for the processing of debris from other stations, as well as its own.
