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.
