A PROGRAM AND CROSS-SECTION LIBRARY TAPE SYSTEM FOR THE ARMY PRESSURIZED WATER REACTOR CODE
A system of IBM 7090 FORTRAN-II and FAP subroutines for preparing program and cross-section library tapes is described. These subroutines are intended primarily for use with the Army Pressurized Water Reactor Code (APWRC), but many of their features and advantages make them useful for other codes also, particularly those in the planning stages. The program library subroutines are added to an existing code by means of a single CALL statement. They provide a diagnostic edit for any of the standard FORTRAN-II I/O (input-output) halts and for any logical halts which the programmer cares to include in FORTRAN-II source programs. The same routines also allow any program containing them to be written on a reference library tape without need for further modification. This program library tape is the foundation for the automated APWRC. Channel trapping is used to search for a program on this tape while calculations are proceeding in the central processing unit of the computer. Rapid program access is thus provided without the disadvantage of writing large decks on a temporary magnetic tape at each application, as with the FORTRAN-II CHAIN function. The subroutines require the first 1700-8 core locations. All necessary information for generating, using, and modifying the three cross section versus energy files required by APWRC is presented.
