In February 2009, NuGeneration (NuGen), a consortium of GDF Suez, Iberdrola and Scottish and Southern Energy (SSE), announced plans to build a new nuclear power station of up to 3.6GW capacity at Sellafield.

In March 2012 five of the 310-tonne boilers were moved from the station to Sweden for decontamination and recycling. In December 2013 the Nuclear Decommissioning Authority selected Berkeley as the preferred interim store for Intermediate-level waste from the decommissioned Oldbury nuclear power station. This became operational in 2014. Berkeley is one of four nuclear power stations located close to the mouth of the River Severn and the Bristol Channel, the others being Oldbury, Hinkley Point A and Hinkley Point B.
