SUPPLEMENTARY INFORMATION: Verification & Validation of Selected Fire 
Models for Nuclear Power Plant Applications.

Draft NUREG-1824, ``Verification & Validation of Selected Fire Models 
for Nuclear Power Plant Applications''

    The purpose of this document entitled ``Verification & Validation 
of Selected Fire Models for Nuclear Power Plant Applications'' Draft 
Report for Comment (NUREG-1824), is to document the verification and 
validation of five (5) fire modeling tools commonly used in nuclear 
power plant (NPP) applications. This project was performed in 
accordance with the guidelines described in the American Society for 
Testing and Materials (ASTM) Standard E 1355-04, ``Evaluating the 
Predictive Capability of Deterministic Fire Models.'' Under a joint 
Memorandum of Understanding (MOU), the NRC Office of Nuclear Regulatory 
Research (RES) and the Electric Power Research Institute (EPRI) have 
agreed to collaboratively develop this technical document to support 
the application of these fire modeling tools in nuclear power plants. A 
library of typical NPP fire scenarios, and information on the ability 
of specific fire models to predict the consequences of typical NPP fire 
scenarios are provided. Technical review of fire models is necessary to 
ensure that analysts can judge the adequacy of the scientific and 
technical basis for the models, select models appropriate for a desired 
use, and understand the levels of confidence that can be placed in the 
results predicted by the models. This work was performed using state of 
the art fire dynamics calculation methods/models and the most 
applicable fire test data. Future improvements in the fire dynamics 
calculation methods/models and additional fire test data may impact the 
results of these reports.
    The NRC is seeking public comment in order to receive feedback from 
the widest range of interested parties and to ensure that all 
information relevant to developing this document is available to the 
NRC staff. This document is issued for comment only and is not intended 
for interim use. The NRC will review public comments received on the 
document, incorporate suggested changes as necessary, and issue the 
final NUREG-1824 for use.

    Dated at Rockville, MD, this 18th day of January 2006.

    For the Nuclear Regulatory Commission.
Charles E. Ader,
 Director, Division of Risk Analysis and Applications, Office of 
Nuclear Regulatory Research.
