Morland eventually concluded that the "secret" was that the "primary" and "secondary" were kept separate and that radiation pressure from the "primary" compressed the "secondary" before igniting it. When an early draft of the article, to be published in "The Progressive" magazine, was sent to the DOE after falling into the hands of a professor who was opposed to Morland's goal, the DOE requested that the article not be published, and pressed for a temporary injunction. The DOE argued that Morland's information was (1) likely derived from classified sources, (2) if not derived from classified sources, itself counted as "secret" information under the "born secret" clause of the 1954 Atomic Energy Act, and (3) was dangerous and would encourage nuclear proliferation.
