Experimental study of hydrogen formation and recombination under postulated LMFBR accident conditions
The report describes an experimental study of hydrogen jets burning in air, hydrogen formation by sodium in humid air atmospheres, and the effects of nitrogen, water vapor sodium vapor/aerosol, jet velocity, and jet temperature on ignition of hydrogen jets. The results show that hydrogen jets above 1450/sup 0/F (788/sup 0/C) issuing into an air atmosphere need no ignition source for ignition, a hydrogen jet temperature higher than 500/sup 0/F (260/sup 0/C) and containing more than six grams of sodium per cubic meter of jet gas will auto-ignite in an air atmosphere, the burning efficiency of a hydrogen jet decreases rapidly to zero when the oxygen concentration outside the flame region approaches 10 percent, and hydrogen does not form from a sodium-nitrogen jet issuing into a humid air atmosphere until the ratio O/sub 2//(H/sub 2/O + O/sub 2/) is less than 0.5.
