Sizewell is the name of a place on the coast of Suffolk, in eastern England, and of the nuclear power stations built there — huge works that make electricity by splitting atoms. When people say Sizewell they usually mean those stations. There are two: Sizewell A, the older one, and Sizewell B, the newer one. Sizewell A has been shut down and is being taken apart; Sizewell B still makes electricity. For years the news has also talked about a planned Sizewell C. The name is a proper noun — a place, not a kind of thing — so it takes a capital letter. English speakers use it the way they use other plant names in the news: the place and the works have become one idea. It is an ordinary British coastal site, not a disaster name. You will meet it in news about energy and British politics more than in novels. Learners do not need it for daily chat; it is a geography-and-news word.
