Fun fact: you can see they "No photography" signs on GCHQ's gates from Google Street View, but super low resolution, making them unreadable. They must have made a deal: Google gives its Street View data with uncensored plate numbers/faces, and GCGQ allows them to film in front of their building at low resolution! The sign actually shows up on their first Instagram post when they created one in 2018 www.gchq.gov.uk/news/gchq-joins-instagram | inews.co.uk/news/uk/gchq-instagram-puzzles-photography-hobbies-216444 Just passing in front of the damn place with Google Maps on must increase your "interest score"!
Production is fully concentrated at Los Alamos National Laboratory in the United States as of 2020. TODO was it ever made anywhere else?

By taking government funding (directly or indirectly through subsiding enrolment fees?), they have to follow some government rules, and all major ones do it seems: academia.stackexchange.com/questions/49187/in-what-sense-are-uk-universities-public/49188
In the University of Cambridge for example, all MA degree holders or higher appear to have some voting power: www.cam.ac.uk/about-the-university/how-the-university-and-colleges-work/governance (archive)
This adds an extra layer of difficulty for the average taxpayer to make changes to university policy, e.g. making universities publish all material with Creative Commons licenses. At most, voters could require this indirectly through the government funding requisites. It is a mess.
Not even the Open University seems to be very open!
Ciro Santilli once attended a round table in the early 2020s where a University of Oxford official from the IP licensing department. The University of Oxford took a 20% equity on spin-off companies, not an uncommon University IP ownership policy at the time. At one point, the officer clearly justified this along the following very official sounding lines (paraphrased):While noble sounding, this immediately reminded Ciro of instrumental convergence, in the field of AGI philosophy. Or in other words, of course the best approach to maximize education and research outcomes of society is to first take over the world, and then implement those goals from there!

The university is a charity with the goal of promoting education and research. All money obtained is reinvested in furthering education and research.
Notably, the University of Oxford was extremely protective of its learning material at that time, which was highly paywalled behind university logins, presumably with the rationale of having unique learning materials to enroll more paying undergrads. How can giving out free information to all not be the optimal way to "promoting education and research" is very hard to envision.

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.
