Evaluation of Fire Models for Nuclear Plant Fire Safety and Risk Analysis
By Monideep Dey, PhD
Preface
This report by Monideep Dey presents the results of an evaluation of fire models for nuclear plant fire safety and risk analysis he conducted during his assignment at the National Institute of Standards and Technology (NIST) by the US Nuclear Regulatory Commission. The main objective of this report, which is based on his detailed technical reports listed below, is to highlight the current limitations of fire models for nuclear plant fire safety analysis. The validation studies conducted by Monideep Dey were the first validation studies conducted at NIST of its fire calculation models, CFAST and FDS.
Abstract
This report presents the results of blind analyses that were conducted to derive the predictive capabilities of specific fire models developed by NIST for nuclear plant fire scenarios. The analyses indicate that the fire models at the present are limited in predicting some parameters of interest in nuclear plant fire safety and risk analysis. Bounding calculations of those parameters can still be conducted as long as the uncertainties in the model predictions are taken into account. Research and improvement programs should be conducted to overcome these limitations so that the fire models become a more useful tool for nuclear plant fire safety analysis.
