The Systems Analysis Programs for Hands-on Integrated Reliability Evaluations (SAPHIRE) is a software application developed for performing a complete probabilistic risk assessment (PRA) using a personal computer. SAPHIRE is primarily funded by the U.S. Nuclear Regulatory Commission (NRC) and developed by the Idaho National Laboratory. This report is intended to assist the user to enter PRA data into the SAPHIRE program using the built-in MAR-D ASCII-text file data transfer process. Towards this end, a small sample database is constructed and utilized for demonstration. Where applicable, the discussion includes how the data processes for loading the sample database relate to the actual processes used to load a larger PRA models. The procedures described herein were developed for use with SAPHIRE Version 6.0 and Version 7.0. In general, the data transfer procedures for version 6 and 7 are the same, but where deviations exist, the differences are noted. The guidance specified in this document will allow a user to have sufficient knowledge to both understand the data format used by SAPHIRE and to carry out the transfer of data between different PRA projects.

EXECUTIVE SUMMARYThe Data Loading Manual contains an overview of functions for creating event trees and fault trees, defining accident sequences and basic event failure data, solving system fault trees and accident sequence event trees, quantifying cut sets, performing sensitivity and uncertainty analyses, documenting the results, and generating reports. The process of creating a SAPHIRE project is described in terms of the ASCII-formatted data structures available via the MAR-D option. MAR-D is a mechanism in SAPHIRE to import or export probabilistic risk assessment data -via a nonproprietary text format -for use, modification, or storage outside of SAPHIRE.In order to understand the data import/export functionality, one must understand the parts of a SAPHIRE project. A project is any grouping of fault trees and event trees with their associated basic events, cut sets, reliability data, and descriptions. Inside a project, SAPHIRE reserves storage areas for the various types of information. For example, all basic event data is automatically placed in the base case part of the database (the "current case" part of the database is used only when performing an analysis). Note that basic fault tree and event tree logic remains the same for both current and base cases.The tutorial in this document leads the student through (a) the basic construction of event tree and fault trees, (b) entering basic event data, and (c) generation and quantification of both fault tree and sequence cut sets. Once the project is complete, the data structures related to the fault trees, event trees, and basic events are discussed. The example that is used is one of modeling upset conditions related to going to work. Consequently, a "going to work" event tree and associated fault trees are used.One application of the data files that are available from SAPHIRE is for use in qualit...
