* High-energy neutrons can produce [[tritium]] from [[lithium-7]] in an endothermic process, consuming 2.466 [[MeV]]. This was discovered when the 1954 [[Castle Bravo#High yield|Castle Bravo]] nuclear test produced an unexpectedly high yield.<ref name="ieer">{{Cite web|url=http://www.ieer.org/reports/tritium.html#(11)|title=Tritium: The environmental, health, budgetary, and strategic effects of the Department of Energy's decision to produce tritium|last=Austin|first=Patrick|date=January 1996|publisher=[[Institute for Energy and Environmental Research]]|access-date=2010-09-15}}</ref>
