After more than 46 years generating home grown zero-carbon electricity, Somerset powerhouse Hinkley Point B has switched off its second reactor. The station first produced power when Abba’s Mamma Mia was at the top of the charts in 1976. Hinkley Point B Station Director Mr Mike Davies said “This is a day of mixed emotions for all of us. We are justifiably proud of everything this station and its workforce have given to Somerset, and indeed the country, over decades of operations. The huge amount of electricity we’ve produced could have met the needs of every home in the South West for 33 years.”Over the coming weeks and months, teams at Hinkley Point B will undertake major maintenance and improvement projects across the plant to get it ready for the next stage of its life, defueling. This process, expected to last around three to four years, involves removing the remaining nuclear fuel from the reactors and transporting it to Sellafield for storage. Once that work is complete EDF will hand the station to the Nuclear Decommissioning Authority for the next step of its life, decommissioning.
