Nope, and you don't source. In fact the first man-made nuclear reactor was the 'Chicago Pile-1' ( 'https://en.wikipedia.org/wiki/Chicago_Pile-1 https://en.wikipedia.org/wiki/Chicago_Pile-1 ), which was built by the Project Manhattan, exclusively aiming at building a nuclearbomb. In WP's article please don't miss this: "Emilio Segrè later recalled that: I thought for a while that this term was used to refer to a source of nuclear energy in analogy with Volta's use of the Italian term pila to denote his own great invention of a source of electrical energy. I was disillusioned by Fermi himself, who told me that he simply used the common English word pile as synonymous with heap. To my surprise, Fermi never seemed to have thought of the relationship between his pile and Volta's." The world's first reactor used to generate electricity (another one generated some during an experiment in 1948), albeit it wasn't its main purpose, was the 4th reactor, and it started nearly 10 years after: https://en.wikipedia.org/wiki/Experimental_Breeder_Reactor_I https://en.wikipedia.org/wiki/Experimental_Breeder_Reactor_I
