    When you can't see underneath the DELETED stamp, you imagine all sorts of interesting things there. When you can see, it's typically underwhelming, and makes you wonder what the fuss was about. The redacted doc is from 2014, the revealed one is from a microfilm release in 1977.pic.twitter.com/82XKrGB2ky

        Also, amusingly, in 2014 they apparently accidentally released one of the numbers, and a few of the site names/headers, in their attempt to preserve a 1958 "downgrade" stamp...("Site W, Ames, Total Shipped / .00154") I've never seen that particular slip-up before!pic.twitter.com/6F96rCxxYk

        As to the data: graph is of Pu production data for the Manhattan Project BEFORE Hanford was really producing any. So it's small scale (experimental piles, cyclotrons), a total of ~300 grams produced from 1943 to early 1945. The first Pu bombs were 6,190 grams each, by comparison.

        I'm thinking: Site Y: Los Alamos -- Pu239 that's been processed by Hanford and sent to LANL for conversion into bombs. Clinton Labs. : X-10 Reactor at Oak Ridge, generating plutonium to support various R&D efforts, so that all of Hanford's production can go to bombs?

        At this point (this only goes up to January 1945) Hanford was not yet producing plutonium in quantity. These are all just gram-level amounts — useful for research and planning but not for production.

        The fuss was all about automatic process of any military research born top secret. Thus all military research staff were to develop an instinctive handling of all media associated with their work. Smart moved after idiocy of allowing ~100K stolen docs to reach Kurchatov in USSR.
