Thanks to @suspended and @deimos for the suggestion!
Hey y’all, I am a basin chemistry engineer for the Department of Energy’s Savannah River Site in South Carolina. Our facility stores spent nuclear fuel from a variety of research and experimental reactors underwater. Our specialty is highly-enriched aluminum-clad fuel, but we have a diverse array of unusual fuels from around the world. A good overview of fuel types can be found here.
My primary responsibility is ensuring the basin water is kept highly pure to minimize corrosion to the fuel, as well as ensure it is free of radionuclides to the extent practicable. I’m happy to answer any questions I can about nuclear fuel, nuclear power, radioactive waste, etc.

According to this guy, societal collapse is imminent because a. entropy and b. the high EROI (energy return on investment) afforded to society by the use of energy dense hydrocarbons such as coal and petroleum will decline dramatically in the near future due to the decreasing economic viability of acquiring them and the lack of a similarly high return alternative (barring nuclear fission, which is VeRy DaNgErOuS (and also practically infeasible politically in most countries that can achieve it), and nuclear fusion, which is, of course, perpetually 20 years away) and because this EROI is (according to him) what makes the complexity of modern civilization possible, it is inevitable that we will soon see a corresponding decline in said complexity (collapse). Now there is a section in the wikipedia article that touches on some of these points (Economic influence) so it's not totally junk science (if you trust Wikipedia, that is). However, I'm still struggling to grasp the significance of this figure. As long as our means of acquiring energy is scalable, why does it matter what the EROI is as long as it is greater than 1? if we need to spend one fifth of the energy we get from solar panels on making more, fixing existing ones, and installation, can't we just make a bunch of them to match our energy needs, even if they're growing? What am I missing here?
