4. METHOD OF SOLUTION

PC-PRAISE considers the initiation and/or growth of crack-like defects in piping weldments. The initiation analyses are based on the results of laboratory studies and field observations in austenitic piping material operating under boiling water reactor conditions. The considerable scatter in such results is quantified and incorporated into a probabilistic model. The crack growth analysis is based on (deterministic) fracture mechanics principles, in which some of the inputs (such as initial crack size) are considered to be random variables. Monte Carlo simulation, with stratified sampling on initial crack size, is used to generate weldment reliability results.

The time requirements for the sample problems ranges from 50 minutes to 1.5 hours on 33MHz 80486 with 8MB of RAM.

ESTS0071/01

The program PRAISE was executed at the NEA-DB on a PC DELL Optiplex GXM 5100 equipped with a Pentium processor of 99 Mhz, base memory 640 Kbyte and extended memory 32 MByte. The execution times to run the eleven sample problems of the program PRAISE which are provided with the package are respectively 3, 6, 9, 13, 5, 1, 9, 21, 6, 9, 17 minutes.[ top ]

ESTS0071/01

The program PRAISE was executed at the NEA-DB on a PC DELL Optiplex GXM 5100 equipped with a Pentium processor of 99 Mhz, base memory 640 Kbyte and extended memory 32 MByte, under MS-DOS 6.2 About 1.6 Mbyte of diskspace are required to hold ALL the package files. The filesize of the four executables are: PRAISE.EXE (252 Kbyte), PR_INPUT.EXE (93 Kbyte), PR_PLOT.EXE (151 Kbyte) and HPLASER.EXE (41 Kbyte).[ top ]

ESTS0071/01

The program PRAISE was executed at the NEA-DB under MS-DOS 6.2. The executables of program PRAISE and of the pre-processor program PR_INPUT have been created using the MicroSoft Fortran compiler (Version 5.10) and linker (Version 5.15).[ top ]
