Now, reports Reuters, high-level radioactive waste storage, handling, and even experimentation facilities at Idaho National Lab (INL) are in harm's way, amidst fast-spreading wildfires. INL is a catch-all "interim storage site" for irradiated nuclear fuel, including from U.S. Navy nuclear submarines and aircraft carriers; "Atoms for Peace" high-enriched uranium (HEU) foreign research reactor fuel, originally supplied by to the U.S. to 41 countries overseas, but returned here as a nuclear weapons non-proliferation precaution; and even melted down nuclear fuel from the U.S. commercial nuclear power industry, including from the 1966 "We Almost Lost Detroit" Fermi 1 partial meltdown, and the 1979 Three Mile Island 50% meltdown. INL has published a map and emergency updates on the wildfire; the map contains links with more detailed information about what risky activities take place where on the INL site. As MSNBC reported, a July 2010 wildfire at INL (photo, left) burned power lines, forcing radioactive waste facilities to rely on emergency diesel generators.
