RSICC CODE PACKAGE PSR-448

1. NAME AND TITLE

MAR-D 4.16: Models and Results Database System.

2. CONTRIBUTORS

Idaho National Engineering Laboratory, Idaho Falls, ID, through the Energy Science and Technology Software Center, Oak Ridge, Tennessee.

3. CODING LANGUAGE AND COMPUTER

MODULA-2; IBM PC (P00448IBMPC00).

4. NATURE OF PROBLEM SOLVED

MAR-D 4.16 is a program that is used primarily for Probabilistic Risk Assessment (PRA) data loading. This program defines a common relational database structure that is used by other PRA programs. This structure allows all of the software to access and manipulate data created by other software in the system without performing a lengthy conversion. The MAR-D program also provides the facilities for loading and unloading of PRA data from the relational database structure used to store the data to an ASCII format for interchange with other PRA software. The primary function of MAR-D is to create a data repository for NUREG-1150 and other permanent data by providing input, conversion, and output capabilities for data used by IRRAS, SARA, SETS and FRANTIC.

5. METHOD OF SOLUTION

MAR-D 4.16 is written entirely in MODULA-2 and uses an integrated relational database to store and retrieve the PRA information.

6. RESTRICTIONS OR LIMITATIONS

The maximum number of basic events, fault trees, event trees, accident sequences, and P and ID's is 10000.

7. TYPICAL RUNNING TIME

MAR-D 4.16 running times are a function of the amount of data to be processed.

8. COMPUTER HARDWARE REQUIREMENTS

IBM-PC/XT/AT/PS-2 or 100% compatible computer running DOS 5.0. The PC must have a 640K of RAM, an EGA/VGA compatible monitor and a display adaptor, and a hard disk with at least 5 megabytes of free space. A numeric math co-processor is highly recommended.

9. COMPUTER SOFTWARE REQUIREMENTS

MAR-D was developed at Idaho National Engineering Laboratory and was initially distributed by the Energy Science and Technology Software Center. It was transferred to RSICC and released in March 2001. The executable was run on a Dell Pentium 100 PC in a DOS window of Windows 95 at RSICC. The source code was written in MODULA-2 and is not included in this distribution. The included executables were created under DOS 5.0.
