Formation of flammable hydrogen–air clouds from hydrogen leakage

International Journal of Hydrogen Energy, 2009
Abstract The possibilities of the formation of a flammable cloud over the ground in an open atmosphere from the leakage of hydrogen stored at different temperatures are studied. The dispersion of hydrogen in the stable and unstable atmospheric conditions is determined using the Gaussian dispersion model. The efflux of hydrogen from the storage vessel

Analyzing effective factors on leakage-induced hydrogen fires

Journal of Loss Prevention in the Process Industries, 2016
Abstract Currently, novel energy resources are receiving increasing attention as a response to the limitation in fossil fuels as well as their adverse effects on human health. Hydrogen, one of the most abundant elements on the earth, can be regarded as a new energy source to replace fossil fuels. Therefore, safety assessment of the relating processes

Analysis on Hydrogen Risk Induced by Containment Leakage

Volume 7: Fuel Cycle, Decontamination and Decommissioning, Radiation Protection, Shielding, and Waste Management; Mitigation Strategies for Beyond Design Basis Events, 2017
In-containment hydrogen, produced during severe accident, can largely challenge the integrity of containment, which has been studied for many years. However, Fukushima Dachii accident has shown the possibility of explosion outside containment due to leaked hydrogen, which was never considered before.
