A weapons-grade ring of electrorefined plutonium, typical of the rings refined at Los Alamos and sent to Rocky Flats for fabrication
. Source. The ring has a purity of 99.96%, weighs 5.3 kg, and is approx 11 cm in diameter. It is enough plutonium for one bomb core. Which city shall we blow up today?
Ciro Santilli is mildly obsessed by nuclear reactions, because they are so quirky. How can a little ball destroy a city? How can putting too much of it together produce criticality and kill people like in the Slotin accident or the Tokaimura criticality accident. It is mind blowing really.

The Ultimate Guide to Nuclear Weapons by hypohystericalhistory (2022)
Source. Good overall summary. Some interesting points:
Gun-type fission weapons are the simplest approach and they work with Uranium-235 bombs as you can ignite it with just one explosion.
Gun-type fission weapons don't work with Plutonium-239 because of the presence of Plutonium-240 as an impurity which leads to fizzle.
Good mentions at: youtu.be/dgBDvnqMkT4?t=252
Implosion-type fission weapons are more complicated than gun-type fission weapon because you have to precisely coordinate the detonation of a bunch of explosives.

Oppenheimer's Gamble by Welch Labs
. Source. Fails to mention Plutonium-240 as the source of the problem.
  • youtu.be/W06g7gIfwRE?t=252 cool to learn that the explosive lenses had to be made out of two different types of explosives, slow and fast, to be more symmetrical
Production is fully concentrated at Los Alamos National Laboratory in the United States as of 2020. TODO was it ever made anywhere else?
For nuclear weapons you need a certain level of isotope purity of either plutonium-239 or uranium-235.
And the easiest way by far to achieve this purity is to produce plutonium-239 in a breeder reactor, which allows you to get it out with much cheaper chemical processes rather than costly isotope separation methods.

sgp.fas.org/othergov/doe/pu50yc.html mentions:
The United States Government has used 14 plutonium production reactors at the Hanford and Savannah River sites to produce plutonium for the U.S. nuclear weapons stockpile and DOE research and development programs. From 1944 to 1994, these reactors produced 103.4 metric tons of plutonium; 67.4 MT at Hanford, and 36.1 at Savannah River.
That site also contains a good summary of the closed shutdown reactors in each site. These are publicly disclosed e.g. at: www.hanford.gov/page.cfm/ProjectsFacilities
www.youtube.com/watch?v=qwKhz7BPBLY mentions that before they stopped production at the end of the Cold War, Hanford site produced 2/3 of the total American stockpile, and Savannah River site produced 1/3.
TODO is there any information available on active breeder reactors? Hanford apparently shutdown.

After the closure of the country’s prime plutonium manufacturing plant at Rocky Flats in 1992, where 1,000 to 2,000 pits were produced every year, a highly reinforced 236,000 sq-ft facility built at LANL earlier in 1978 became the first Department of Energy (DoE) facility capable of producing plutonium cores.
Although initially established for plutonium research and development, in 2003 the Plutonium Facility Building 4 (PF-4) within Tech Area 55 at Los Alamos produced the nation’s stockpile quality (first war reserve) plutonium. In 2006, Congress instructed the DoE to focus on producing pits at this facility.
The B Reactor of the facility produced the plutonium used for Trinity and Fat Man, and then for many more thousand bombs during the Cold War. More precisely, this was done at
Located in Washington, in a dry place the middle of the mountainous areas of the Western United States, where basically no one lives. The Columbia river is however nearby, that river is quite large, and provided the water needed by their activities, notably for cooling the nuclear reactors. It is worth it having look on Google Maps to get a feel for the region.
Unlike many other such laboratories, this one did not become a United States Department of Energy national laboratories. It was likely just too polluted.
Reactor of the Hanford site of the produced the plutonium used for Trinity and Fat Man.
This was the first full scale nuclear reactor in the world, and was brought up slowly to test it out.

This was one of the two American plutonium production sites, together with the Hanford site. www.youtube.com/watch?v=qwKhz7BPBLY mentions it produced about 1/3 of the total American plutonium.
www.reuters.com/article/world/americas-nuclear-headache-old-plutonium-with-nowhere-to-go-idUSKBN1HR1JT/ claims that as of 2018 it stored the majority of the plutonium stockpile of the country.
It's where most American nuclear weapons are assembled and disassembled.

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.

Their website, and in particular the recruitment section, are so creepy.
There's not mention of bombs. No photos of atomic explosions. The words "atomic" and "weapon" do not even show up in the front page!!! The acronym AWE is instead used everywhere as an euphemism.
In the recruitment section we can see a bunch of people smiling: web.archive.org/web/20211007213222/https://www.awe.co.uk/careers/working-at-awe/, suggesting:
We make nukes, and we do it with a smile!
There's even children outreach!!!
Ciro Santilli is not against storing a few nukes to be ready against dictatorships. But don't be such a pussy! Just say what the fuck you are doing more clearly! You are making weapons to kill people and destroy things in order to maintain the Balance of power. If the public can't handle such facts, then shut down the fucking program.

Documentary about American ICBM crews working on the Francis. E. Warren Air Force Base. Wiki mentions that there are 3 main sites in the USA, and plainshumanities.unl.edu/encyclopedia/doc/egp.ii.042 suggests all/most of them are in the Great Plains area. They operate a Minuteman system, which as of 2021 is the only nuclear ICBM system in the USA.
Good documentary, shows well the day-to-day life of the operator, including outside of the work site.
