- Abstract
- As the use of fire modeling tools increases in support of day-to-day nuclear power plant applications the importance of verification and validation (V&V) studies for these tools also increases. V&V studies afford fire modeling analysts confidence in applying analytical tools by quantifying and discussing the performance of the given model in predicting the fire conditions measured in a particular experiment. The underlying assumptions, capabilities, and limitations of the model are discussed and evaluated as part of the V&V study. The main objective of this report is to document a V&V study for the MAGIC zone model, in accordance with ASTM E 1355, Standard Guide for Evaluating the Predictive Capability of Deterministic Fire Models. MAGIC is a zone model developed and maintained by Electricité de France (EdF), which officially released the latest version of the model (Version V4.1.1b) in 2005. The MAGIC software calculates fire-generated conditions (e.g., hot gas layer temperature, etc) in single- or multi-compartment geometries as a function of time. The MAGIC software is a classical two-zone model for fire simulations, with capabilities to process multi-compartment problems. Each compartment is divided into two volumes, which are assumed to have homogeneous thermo-physical properties. The solution of the mass and energy balances accumulated in each zone, together with the ideal gas law and equation of heat conduction into the walls, results in the predicted environmental conditions generated by the fire.
