The key design features of commercial gas-cooled reactors are presented. The majority of gas-cooled reactors were built in the UK and in France, with the former country progressing their development into the 1980s and beyond whilst France concentrated on water-cooled reactors. The progression from uranium metal fuelled reactors (known as ‘Magnox’ in the UK) to Advanced Gas-Cooled Reactors is discussed, with further discussion of high-temperature gas-cooled reactors and proposed Generation IV plant. The topics discussed include: design of pressure vessels; design of fuel; refuelling; ...
