4. NATURE OF PROBLEM SOLVED

SAPHIRE is a collection of programs developed for the purpose of performing those functions necessary to create and analyze a complete Probabilistic Risk Assessment (PRA) primarily for nuclear power plants. The programs included in this suite are the Integrated Reliability and Risk Analysis System (IRRAS), the System Analysis and Risk Assessment (SARA) system, the Models And Results Database (MAR-D) system, and the Fault tree, Event tree and P&ID (FEP) editors. Previously these programs were released as separate packages. These programs include functions to allow the user to create event trees and fault trees, to define accident sequences and basic event failure data, to solve system and accident sequence fault trees, to quantify cut sets, and to perform uncertainty analysis on the results. Also included in this program are features to allow the analyst to generate reports and displays that can be used to document the results of an analysis. Since this software is a very detailed technical tool, the user of this program should be familiar with PRA concepts and the methods used to perform these analyses.
 

5. METHOD OF SOLUTION

SAPHIRE is written in MODULA-2 and uses an integrated commercial graphics package to interactively construct and edit fault trees. The fault tree solving methods used are industry recognized top down algorithms. For quantification, the program uses standard methods to propagate the failure information through the generated cut sets.

SAPHIRE includes a separate module called the Graphical Evaluation Module (GEM). GEM provides a highly specialized user interface with SAPHIRE which automates the process for evaluating operational events at commercial nuclear power plants. Using GEM an analyst can estimate the risk associated with operational events (that is, perform a Level 1, Level 2, and Level 3 analysis for operational events) in a very efficient and expeditious manner.

This on-line reference guide will provide an introduction to SAPHIRE Version 6.6x and 7.0x software. A brief discussion of the purpose and history of the software is included along with general information such as installation instructions, starting and stopping the program, and some pointers on how to get around inside the program. Next, database concepts and structure are discussed. Following that are nine sections, one for each of the menu options on the SAPHIRE main menu, wherein the purpose and general capabilities for each option are furnished. Next, the capabilities and limitations of the software are provided in a table. Finally, a series of appendices which provide detailed information about some of the complex operations of the software.
 

6. RESTRICTIONS OR LIMITATIONS

Due to the complexity of and the variety of ways a fault tree can be defined it is difficult to define limits on the complexity of the problem solved by this software. It is, however, capable of solving a substantial fault tree due to efficient methods. At this time, the software can efficiently solve problems as large as other software currently used on mainframe computers.
 

7. TYPICAL RUNNING TIME

Running times are a function of the problem to be solved and the actions performed by the user.
 

8. COMPUTER HARDWARE REQUIREMENTS

IBM-PC/XT/AT/PS-2 or 100% compatible computer running DOS 3.3 or higher. For the 16 bit version, the PC must have a 640K of RAM, an EGA/VGA compatible monitor and display adaptor, and a hard disk with at least 10 megabytes of free space. A numeric math co-processor and a mouse are highly recommended. For the 32 bit version, the PC must have a 386 or better processor and a minimum of 2 megabytes of free extended memory and 40 megabytes of free disk space, with a VGA monitor.
 

9. COMPUTER SOFTWARE REQUIREMENTS

IBM/Microsoft DOS version 3.3 or later; for the Windows version Windows 95, 98, NT.
