Enrico Fermi relocates to the Chicago Met Lab. He builds an experimental pile in the Stagg Field squash courts with a projected k value of 0.995, then begins planning the construction of the world's first man-made critical pile, to be called CP-1. Fermi's efforts now shifts from demonstrating feasibility to securing graphite and uranium of adequate purity and in sufficient quantity to build the reactor.
