After the Second World War, in 1946, despite the participation of many British scientists in the Manhattan Project, and formal agreement of a joint technology-exchange program, the United States government passed legislation that closed its nuclear weapons program to all other countries. The British government, not wanting to be left behind as a world power in an emerging arms race, then embarked on a programme to build its own atomic bomb as quickly as possible. The Windscale Piles The reactors were built in a short time near the tiny village of Seascale, Cumberland, and were known as Windscale Pile 1 and Windscale Pile 2, housed in large, concrete buildings a few hundred feet from one another. The reactors were graphite-moderated and air-cooled. Because nuclear fission produces large amounts of heat, it was necessary to cool the reactor cores by blowing cold air through channels in the graphite. Hot air was then exhausted out of the back of the core and up the chimney. Filters were added late into construction at the insistence of Sir John Cockcroft and these were housed in galleries at the very top of the discharge stacks. They were deemed unnecessary, a waste of money and time and presented something of an engineering headache, being added very late in construction in large concrete houses at the top of the 400-ft chimneys.
