Historic, unique Manhattan Project footage from Los Alamos by Los Alamos National Lab
. Source. Mostly the daily life part of things, but very good, includes subtitles explaining the people and places shown.
Marked with identifier "LA-UR 11-4449".
Getting funding for the Chicago Pile Edward Teller interview by Web of Stories (1996)
Source. - youtu.be/mnScq24BEmc?t=114 the main cost for the reactor was the graphite. Presumably they already had the uranium in hand?. Edit, no, it is because it was a specialized graphite: Video 2. "German graphite from The Genius Behind the Bomb (1992)", i.e. nuclear graphite.
German graphite from The Genius Behind the Bomb (1992)
Source. Graphite was expensive because it had to be boron-free, since boron absorbs neutrons. But a boron process was the main way to make graphite. This type of pure graphite is known as nuclear graphite.The lab that made Chicago Pile-1, located in the University of Chicago. Metallurgical in this context basically as in "working with the metals uranium and plutonium".
Given their experience, they also designed the important X-10 Graphite Reactor and the B Reactor which were built in other locations.
Plutonium-based.
Its plutonium was produced at Hanford site.
Trinity: Getting The Job Done
. Source. Good video, clarifies several interesting technical points:- Gun-type fission weapon were much easier to build as you don't need super synchronized charges as in implosion-type fission weapon. But they are less efficient.
- Plutonium make much more efficient usage of uranium, because you don't need to highly enrich a bunch of Uranium-235 in the first place, but rather just use way less enriched Uranium-235 to produce a bunch of Plutonium by converting Uranium-238

The Manhattan Project was a secret research and development initiative undertaken by the United States during World War II to create the first nuclear weapons. It began in 1942 and involved collaboration between the U.S., the United Kingdom, and Canada. The project was driven by the fear that Nazi Germany was developing its own atomic bomb and aimed to harness the power of nuclear fission. Key figures in the project included physicist J.
