- Abstract
- This document provides guidance to Department of Energy (DOE) facility analysts in the use of the CFAST computer software for supporting Documented Safety Analysis applications. Information is provided herein that supplements information found in the CFAST documentation provided by the code developer. CFAST is one of six computer codes designated by DOE's Office of Environmental, Safety and Health as a toolbox code for safety analysis. The Defense Nuclear Facilities Safety Board issued Recommendation 2002-1 on Quality Assurance for Safety-Related Software in September 2002. The Recommendation identified a number of quality assurance issues for software used in the Department of Energy (DOE) facilities for analyzing hazards, and designing and operating controls that prevent or mitigate potential accidents. The development and maintenance of a collection, or "toolbox," of high-use, Software Quality Assurance (SQA)-compliant safety analysis codes is one of the major commitments contained in Implementation Plan for Recommendation 2002-1 on Quality Assurance for Safety Software at Department of Energy Nuclear Facilities. In time, the DOE safety analysis toolbox will contain a set of appropriately quality-assured, configurationcontrolled, safety analysis codes, managed and maintained for DOE-broad safety basis applications (DOE, 2002b). The Consolidated Fire and Smoke Transport (CFAST) code is one of the designated toolbox codes. CFAST is a zone-based fire model, which was developed by the National Institute of Standards and Technology. The code has been widely used in the fire protection community to support alternate design approaches, post-fire investigations and as a research tool to better understand fire phenomena. This report sanctions the use of the two NIST supported versions, CFAST 3.1.7 and CFAST 5.1.1. The report explains the advantages of both versions.
