PREP (Fault Tree Pre-Processor): A Computer Program to Facilitate Use of the SETS Computer Program for the Savannah River Reactor PRA.

摘要

As part of the contract to provide technical support to the PRA for the Savannah River Reactors, Science Applications International Corporation (SAIC) has developed a computer program to facilitate the use of the SETS computer program in the solution of Fault Trees and Event Trees for the PRA. The PREP (Fault Tree Pre-processor) program is used to simplify user input for the SETS fault tree evaluation program. This includes a simple fault tree input format, linking of data and flag settings, error detection to assure that the SETS job will not abort due to incorrect input, and linking of many fault trees into many event tree sequences. The program is designed to run on a VAX computer operating with VMS. The created SETS input file can be transmitted to CRAY computer (currently at LANL) to run SETS. With simple modification, PREP can be adapted to run directly on a CRAY. It is anticipated that use of the PREP program by the Risk Analysis Group will identify the need for additional improvements. These improvements will be implemented as they are identified. In partial fulfillment of contract scope of work requirements, SAIC has submitted a manual for use of PREP and the program listing for PREP. These are included as attachments A and B respectively. Attachment B is included in selected copies only. (ERA citation 13:045002)
