Evaluation of Fire Models for Nuclear Power Plant Applications: Cable Tray Fires



M K. Dey


This technical reference document was developed in the International Collaborative Project to Evaluate Fire Models for Nuclear Power Plant Applications. The objective of the collaborative project is to share the knowledge and resources of various organizations to evaluate and improve the state of the art of fire models for use in nuclear power plant fire safety analysis. This volume reports on the results of the first task in the international collaborative project. The objective of the first task was to evaluate the capability of fire models to analyze cable tray fires of redundant safety systems in nuclear power plants. The evaluation of the capability of fire models to analyze these scenarios was conducted through an international benchmark exercise. Consideration of appropriate input parameters and assumptions, interpretation of the results, and determination of the adequacy of the physical sub-models established useful technical information regarding the capabilities and limitations of the fire models. The participants in the benchmark exercise determined that the results indicate that the models provide a comprehensive treatment of most physical phenomena of interest in the scenarios analyzed. The predicted trends from the models were found to be similar and reasonable for their intended use. These fire models can provide useful results for nuclear power plant fire safety analysis for the types of scenarios analyzed.
