Yeah it reminds me of the Smyth report, published in August 1945 about atomic bombs, commissioned by the director of the real Manhattan Project. It’s fine to reveal knowledge in detail, if it doesn’t reveal anything related to constructing the apparatuses (the chemistry and the metallurgy) needed.

The press release following the bombing of Hiroshima specifically stated which method of refining Uranium was used. The U.S. spent a great deal of time, effort, and money on researching and testing four different enrichment systems. Just that one detail saved the Soviets 3/4s of a sizeable chunk of the A-bomb effort. Sometimes you don't need to leak much detail to give away a great deal.

		Do you have the press release in question? I'd be very curious to see it. All I found at a glance was Truman's well-known one (https://www.atomicarchive.com/resources/documents/hiroshima-...) which was followed by the Secretary of War's (https://www.ibiblio.org/pha/policy/1945/450806b.html) and neither seem to mention anything about enrichment methods or even the concept of isotope separation.
