“…Kai Wang investigated the effect of a high pressure hydrogen leak model with multi-parameters to the distribution of hydrogen flammable area [14]. Zhaolin Wang et al examined the heat and chemical hazard for the integration of nuclear reactors and thermochemical hydrogen plants [15]. Verfondern et al examined the release, dispersive transport, and explosion of a hydrogen cloud in the atmosphere as well as the release of toxic substances from the JAEA design of an HTGR-S-I hydrogen production plant and their transport towards the NPP control room [16] and Sato et al suggested safety requirements and design considerations of such a system [17].…”
