This is probably the primary project related to this at present in the US, a liquid-metal cooled design coupled to a molten salt storage system (also used in solar thermal systems, mirror-field collectors): https://www.nextbigfuture.com/2024/06/natrium-soduim-cooled-fast-reactor-starts-construction.html https://www.nextbigfuture.com/2024/06/natrium-soduim-cooled-... The bill itself requires some reports from the DOE to Congress. Any guesses on how big this number will be? > "Not later than January 1, 2026, and biennially thereafter, the Secretary of Energy shall submit to Congress a report that describes... the projected lifecycle costs to store, manage, transport, and dispose of the projected inventory of spent nuclear fuel and high-level radioactive waste in the United States, including spent nuclear fuel and high-level radioactive waste expected to be generated from existing reactors through 2050." The Chinese have introduced pebble-bed reactors with helium and graphite, and they're apparently capable of going into cool shutdown under a complete loss-of-power incident without melting down, and can produce high-temperature steam for industrial processes as well as electricity. https://en.wikipedia.org/wiki/HTR-PM https://en.wikipedia.org/wiki/HTR-PM https://www.modernpowersystems.com/news/chinas-htr-pm-reactors-achieve-full-power-11406071/ https://www.modernpowersystems.com/news/chinas-htr-pm-reacto...
