Physics of Nuclear Reactors: Gas-Cooled Reactors

This lecture covers the basic principles of nuclear power plants, including nuclear fission, reactor concepts, neutron diffusion, multigroup theory, and advanced technologies like gas-cooled reactors. It discusses the advantages and disadvantages of gas-cooled reactors, focusing on the Magnox and AGR fuel types. The presentation delves into early Magnox reactors, their components, and the evolution towards AGR designs. It explores the improvements in gas ducts, the largest Magnox reactor at Wylfa, and the development of AGR technology. The lecture also touches on high-temperature gas-cooled reactors, their efficiency, combined cycle plants, and the production of fuel kernels. It concludes with a detailed look at TRISO fuel particles, fuel element designs, and HTGR prototype plants worldwide.
