3. DESCRIPTION OF PROGRAM OR FUNCTION
WLUP contains validated WIMS-D formatted cross section libraries in 69 and 172 energy group structures for nuclear reactor calculations. Materials from recently released evaluated nuclear data libraries are included. The NJOY nuclear data processing system was applied for generating the cross section files following the models and conventions built into the WIMS-D lattice code. The relevant features for the WIMS users are:
- Energy group structures: 69 and 172 energy groups.
- List of materials: WIMS ID, general information, source of data.
- Cross sections: 69 and 172 group plots.
- Resonance data: WIMS ID, temperature, background cross sections.
- Goldstein-Cohen factors: Goldstein-Cohen lambda values.
- Thermal scattering data: thermal scattering laws and P1 matrixes.
- Fission spectrum: fission spectrum data.
- Burnup data: burnup chains.
- Fission product yields: fission yield tables.
- Pseudo lumped fission product: Description of pseudo fission
product.
- Energy release by fission: table of energy released by fission.
- Dosimetry data: dosimetry reactions, source of data.
- Averaging flux and current spectra: flux and current spectra
plots (Numerical data on NJOY inputs).
- WIMSD5B updates: WIMSD5B extensions and updates.
- Processing methods: Brief description on processing methods.

IAEA1408/03
This version differs from the previous one in the following:
Main changes up to 28 January 2008.
- Due to a bug in NJOY processing multigroup data the WIMS-D library based on ENDF/B-VII data was incorrect. Only the Th-232 and Pa-231,233 data are affected.
- Corrected WIMSD libraries based on the ENDF/B-VII.0 data were uploaded.
- Plots were updated.
- The differences between the original and the corrected results for the standard benchmarks can be seen in E70_bug.lst
- New WIMSD libraries were added based on the ENDF/B-VII.0 library.
- Some programs, procedures and data files were updated.
- The IAEA evaluated nuclear data files were uploaded to the website.
- New list files were added to the XnWlup package.
