atomic pile
nounEtymology
From the fact that the first nuclear reactor, at the University of Chicago in 1942-1943, was literally constituted by a tall pile (heap) of graphite moderator blocks. Compare also charcoal pile, a traditional improvised kiln used in charcoal making, which uses a similar basic design to contain a volatile process. The fact that English pile also is related to French pile (“battery”) (with senses of a collection of components and a power source, often both coinstantiated) has also been noted as an interesting nexus of word roots and semantic themes.
