1. NAME AND TITLE

WILIT: A Utility Program for WIMS Libraries.

2. CONTRIBUTOR

Nuclear Research Institute, Rez near Prague, Czechoslovakia.

3. CODING LANGUAGE AND COMPUTER

Fortran 77 IBM PC and compatibles, DEC VAX (P00344/MNYCP/00).

4. NATURE OF PROBLEM SOLVED

WILIT is a utility program for use with WIMS libraries. The following functions can be performed: conversions between binary and card-image form; extraction of data for specified material and re-inclusion (after possible editing) in the library with different identification number; reduction of library contents (number of materials); comparison of selected data sets with interpolation in resonance integral tables; replacement of fission spectrum; inclusion of cross sections calculated by FEDGROUP-R in the library.

5. METHOD OF SOLUTION

One of three interpolation schemes (WIMS, Segev's, Greene's) are used when comparing data from resonance integral tables.

6. RESTRICTIONS OR LIMITATIONS

None noted.

7. TYPICAL RUNNING TIME

The test input cases ran in 4 minutes 21 seconds on a Northgate 486/66 using NEA0329/13 (WIMS library).

8. COMPUTER HARDWARE REQUIREMENTS

WILIT runs on DEC VAX and IBM PC and compatibles. A minimum of 5 MB hard disk space is recommended to install, compile and run all the test input cases.

9. COMPUTER SOFTWARE REQUIREMENTS

The MS Fortran V5.0 and MS Linker were used to create the executable included in the package. The VAX Fortran compiler is required to implement code under VAX/VMS.
