The HyRAM toolkit is the first-ever software toolkit that integrates deterministic and probabilistic models for quantifying accident scenarios, predicting physical effects, and characterizing hydrogen hazards’ impact on people and structures. HyRAM incorporates generic probabilities for equipment failures and probabilistic models for heat-flux impact on humans and structures, with computationally and experimentally validated models of hydrogen release and flame physics.
The initial modules can be used to quantify the likelihood and thermal consequences associated with gaseous hydrogen releases from user-defined hydrogen installations. Future development activities will integrate additional consequence models and develop user interfaces for additional audiences. When completed, the toolkit will enable industry-, SDOs (standards development organizations)-, and CDO (code development organizations)-led quantitative risk assessment and performance-based engineering with state-of-the-art, validated science and engineering models.
The HyRAM software is available under an open source license. The source code for HyRAM is available here. The most recent build of the Windows-only installer is available here.
