Overt Intelligence on Atomic Energy

It cannot be too greatly emphasised that any such programme showing even the possibility of success must of necessity be tremendous, calling for a scientific, technical, industrial and administrative effort of the first magnitude, and an enormous expenditure of wealth and man-power hours. Nuclear Energy, as we at present know it, is derived from, or inaugurated by, the fission of an isotope of the metal Uranium, of which there is 0.7% present in normal Uranium. There is as yet no known method of releasing Atomic Power, nor yet of manufacturing an Atomic Bomb, to which Uranium is not essential.
