After 44 years of service, the world's oldest operating nuclear power plant - the UK's Oldbury - has been shut down.
Back in 2008, the plant - which is operated by Magnox Ltd, which is owned by Energy Solutions - had its life extended to the end of 2012, but its managers have opted to switch it off early.
Reactor two was turned off last year and now reactor one was shut down at 11:00 GMT on Wednesday, ending the Bristol-based plant's operations.The site now must undergo a series of decommissioning procedure which involve removal of spent fuel, management of waste and demolition of the buildings - a delicate process that will take decades to complete.
The removal of spent fuel should take about 15 years, but the longest procedure will letting the site drain its remaining radioactivity - a process that involves little human intervention and could take approximately 80 years.
However, while the site is being shut down, plans for a neighboring plant are already in the works. Horizon Nuclear Power - a conglomerate formed by E.On and RWE - is looking to build a new station in the same area by 2025.
According to the UKPA, Oldbury was one of the first nuclear power stations in the world to generate electricity of a commercial scale.
"Oldbury has a long and proud history of safely generating electricity. Our thanks go to the Magnox workforce, who have been extremely committed to maximizing the plant's generating life, ensuring it was safely able to continue past its original planned closure date," said Dr Brian Burnett, NDA head of programs.
