- Abstract
- As the use of fire modeling tools increases in support of day-to-day nuclear power plant (NPP) applications including fire risk studies, the importance of verification and validation (V&V) studies for these tools also increases. V&V studies afford fire modeling analysts confidence in the application of 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. In August 2002, the Electric Power Research Institute (EPRI) published for the first time the Fire Modeling Guide for Nuclear Power Plant Applications (EPRI TR-1002981). This fire modeling guide provides fire protection engineers in the commercial nuclear industry a broad overview of fire modeling theory and applications, including representative calculations performed with various state-of-the-art fire models. With this guide, EPRI included a library of pre-programmed in Microsoft® Excel® equations, which are used to estimate some aspects of fire-generated conditions. This collection of equations is referred to as Revision 1 of the Fire-Induced Vulnerability Evaluation model (FIVE-Rev1). In general, the equations in the library are closed-form analytical expressions that can be solved by hand. The capabilities of the various equations in the library include predicting temperature and convective heat fluxes in the fire plume or ceiling jet, irradiated heat flux, upper-layer temperature, time to detection, and target heating, among others. The main objective of this study is to document a V&V study for selected models in the FIVERev1 library, in accordance with ASTM E 1355, Standard Guide for Evaluating the Predictive Capability of Deterministic Fire Models. As such, this report is structured to follow the guidance provided in the ASTM standard.
