One objective of the hydrogen behavior program is to develop the technical data and scientific understanding necessary to defensibly revise safety codes and standards. This includes the behaviors of a hydrogen release, dispersion, accumulation, ignition, flame radiation, and overpressure. The team develops models to describe these phenomena and generates high-fidelity data that can be used to validate and verify these models. This work provides the physics necessary to inform quantitative risk assessment (QRA)
and the HyRAM tool being developed in DOE’s Safety, Codes and Standards Program.
