Wylfa Nuclear Power Station spent fuel reprocessing plant at Sellafield. Springfields Fuels Limited ended production of Magnox fuel elements in 2008 due to these plans. However, in 2010 the NDA announced an extension to 2012, beyond Wylfa's 40th anniversary as a generating power station in January 2011, due to schedule slippage at Sellafield which would allow Wylfa additional time before final defuelling. At this time, a strategy was also devised to maximise the generation from the remaining fuel stock given that new fuel could no longer be manufactured. This required a change in the distribution of fuel within the reactors, as well as the
Hartlepool Nuclear Power Station for a prototype fluidised bed combustion (FBC) coal station at Grimethorpe in Yorkshire. Because of this, the UK missed out on pioneering FBC technology, before it became internationally recognised as the best way of burning coal. Sited from Seaton Carew, and in the middle of the industrial complex of Teesside, the station was to be built closer to any major urban area than any nuclear power station site had been. To make this acceptable, the station's reactors were to be housed in prestressed concrete pressure vessels. The construction of the power station which was undertaken by Nuclear Design & Construction
