- Abstract
- This document is a panel report on the results and findings of the second benchmark exercise of the International Collaborative Project to Evaluate Fire Models for Nuclear Power Plant Applications. It forms part of an on-going international activity to assess the capability of current fire models for inclusion in fire risk assessments for nuclear power plants. Benchmark exercise # 2 was designed to challenge fire models in respect to their application to large enclosures, and to address complexities introduced by features such as horizontal (hatch) flows between compartments. The exercise was divided into Part I and Part II, each consisting of three separate scenario cases. Simulations were performed with zone, lumped parameter and CFD models. In Part I reasonable agreement between prediction and measurement was achieved with all class of fire model once the controlling mechanisms had been 'correctly' accounted for. Although for Part II there were no experimental measurements, the spread in the predicted values indicated that the modelling of large complex spaces such a turbine hall warrants further investigation.The objective of the International Collaborative Project to Evaluate Fire Models for Nuclear Power Plant Applications is to share the knowledge and resources of various organisations to evaluate and improve the state of the art of fire models for use in nuclear power plant fire safety and fire hazard analysis. The project is divided into two phases. The purpose of the first phase is to evaluate the capabilities of current fire models for fire safety analysis in nuclear power plants. The second phase will extend the validation database of those models, and implement beneficial improvements to the models that are identified in the first phase.
