A bit off subject, but now you've stepped into my former playpen with nuclear weapons design. Untrue. The two WWII bombs were single stage fission bombs; one using Uranium 235 and the other using Plutonium. Lithium in modern thermonuclear weapons is Lithium Deuteride (made by mixing Lithium and Deuterium at high temperature), and is used, not because it burns readily, but because when bombarded with Neutrons from fissioning Uranium, releases large quantities of Tritium, which is a reactive form of Hydrogen used to boost a Hydrogen bomb a.k.a. thermonuclear bomb. Lithium Deuteride can be stored as part of a weapon without significant short term deterioration. Previously, Tritium gas was used, but tritium has a short half life and is also highly corrosive, creating both short and long term maintenance and reliability problems with nuclear arsenals. > > For our professional or volunteer fire fighters, what is being taught to > fight lithium fires now days? Graphite extinguishers are used to suppress metal fires, including Lithium. Yeah, I had to stay current on fire suppression with these materials when I used to work with them.
