they did a whoopsie, lead 210 comes from uranium 238. every 220 years radioactivity drops 1000x which means that 200-300 year old lead is mostly fine. copper notably doesn’t have this problem, is dense and is refined to high degree, at scale. it’s good enough to shield most of relatively low energy radiation from that isotope (less than 50kev gammas). couple mm of copper should be plenty for many applications

different tool for a different purpose. water has a large heat of evaporation which is something that allows for more compact turbines

big advantage is that molten salt allows for energy storage for nighttime

it also happened with tramadol before (different plant)

Adding to that, logistics are such that direct impact will be felt strongest in places like India that rely heavily on Qatari LNG to make fertilizer, but many places have other sources of both gas and fertilizer. Americas, EU, Russia and China will get by because they have their own supply and will be only affected by price increase

without synthetic nitrogen fertilizer there’s only enough reactive nitrogen going around for something like 1-1.5B people. yea mate very sustainable to retvrn to traditional farming and starve 80% of the planet in the process
