Hinkley Point B nuclear power station was a nuclear power station near Bridgwater, Somerset, on the Bristol Channel coast of south west England. It was the first commercial Advanced Gas Cooled reactor to generate power to the National Grid in 1976 and shares its design with sister station Hunterston B nuclear power station .
The energy group confirmed the plan remains for the Somerset plant to move into the defueling phase by August 1 2022.
On 7 January 2022 Hunterston B reactor 4 was shut down for the last time, ending production after nearly 47 years. Reactor 3 had moved to the defuelling phase in November 2021. [32] On 1 August 2022 Hinkley Point B Reactor 3 was shut down, Reactor 4 was shut down on 6 July 2022. [33]
So that orders could be given to UK manufacturers, and to avoid project risk in dealing with what were at the time newly designed very large turbo-alternator sets, Sizewell B uses two full-speed, 3,000 RPM (50 Hz), nominal 660 MW turbo-alternator sets similar to those used at the AGR power stations Hinkley Point B, Heysham 1, Hartlepool and ...
All seven AGR plants were expected to be shut down in 2022 and in decommissioning by 2028. [30] Hinkley Point B was extended from 40 to 46 years, and closed. The same happened with Hunterston B, also after 46 years. An increasing number of reactors is reaching or crossing their design lifetimes of 30 or 40 years.
The CEGB specified a compact design for the Heysham 1 and Hartlepool power station reactor islands in comparison to the design of the two preceding stations at Hinkley Point B and Hunterston B in order to reduce the capital cost, but this caused expensive construction delays because of restricted access. The Heysham 2 reactor island occupies a ...
Between 2006 and 2013, [130] Hinkley Point B and Hunterston B were restricted to about 70% of normal MWe output because of boiler-related problems requiring that they operate at reduced boiler temperatures. [131] In 2013, these two stations' power increased to about 80% of normal output following some plant modifications. [130]
