To improve a hydrogen safety management technology for long term storage of radioactive wastes such as fuel debris retrieved in the decommissioning of Fukushima Daiichi Nuclear Power Station, a hydrogen behavior simulation code for analyzing its dispersion and combustion has been developing with considering inert gas atmosphere containing steam assumed in a storage container. Trial simulation results of hydrogen dispersion and combustion are reported to understand its steam effects.
