Great British Energy – Nuclear (GBE-N) have announced the site of the UK’s first three Small Modular Reactors (SMRs). The SMRs are due to be sited at Wylfa on the coast of Ynys Môn (Anglesey) in North Wales, which already boasts a proud history of nuclear power generation and a skilled workforce already in place. The new SMRs at Wylfa will support around 8,000 highly skilled, well-paid jobs across the UK during the build programme.
The SMR designs have been developed by TWI Industrial Member company, Rolls-Royce SMR, now selected as the preferred bidder for the next generation of nuclear power stations in the UK. TWI was also involved in the early development of the SMRs, as Rolls-Royce SMR called upon our technical excellence in welding engineering and non-destructive testing to assist them in their assessment of the SMR design for manufacture.
The Rolls-Royce SMR power stations have a footprint the size of two football pitches and are capable of powering one million homes. Each SMR can support both on-grid electricity and a range of off-grid clean energy solutions, enabling the decarbonisation of industrial processes and the production of clean fuels, such as sustainable aviation fuels (SAF) and green hydrogen.
Nine-tenths of each SMR power plant can be built or assembled in factory conditions before final installation and assembly on site. This means there is less on-site construction, greater nuclear security and improved containment efficiency.
Capable of overcoming the financial barriers associated with the creation of conventional nuclear reactors, SMRs offer a carbon free, clean energy alternative to fossil fuels.
