A Primer on Nuclear Safety:2.2 Defense in DepthControlling Nuclear Reactions in Light Water ReactorsEnrico Fermi was the first nuclear scientist to find a solution for controlling chain reactions in a nuclear reactor. Fermi said that his Chicago Pile was a crude pile of black bricks and wooden timbers. Of course natural uranium fuel was added. There was, Fermi realized, something else needed in order to make his reactor safe. That was a means of soaking up the neutrons created by the chain reaction in order to control it. The way Fermi chose to control the Chicago Pile was to insert a n...
