The construction of the power station, which was undertaken by a consortium of AEI and John Thompson,[1] began in 1956.

[2] It had two Magnox reactors producing 276 megawatts (MW) in total – enough electricity on a typical day to serve an urban area the size of Bristol.

[4] Nuclear fuel for Berkeley power station was delivered and removed via the nearest railhead, a loading facility on the Sharpness single railway line.

So far the nuclear decommissioning process has involved the removal of all fuel from the site in 1992, and the demolition of structures such as the turbine hall in 1995 and cooling ponds in 2001.

[7] The next step of decommissioning will be the care and maintenance stage of the nuclear reactor structures, scheduled to commence in 2026, until radioactive decay means that they can be demolished and the site completely cleared between 2070 and 2080.

[8] In March 2012, five of the 310 long tons (310 t) boilers were moved from the station to Sweden for decontamination and recycling.
