The WIMS Library Update Project (WLUP) was organized by the Nuclear Data Section of the IAEA to speed up completion of fully updated libraries for use with WIMS. The “Jozef Stefan” Institute was supported by the IAEA through a research contract to co-ordinate technical issues related with the project. Work on the Coordinated Research Project began in the early 1990’s and was accomplished through the efforts of international participants and contributors, who are listed in the WLUP final report. The new cross section libraries included in this WLUP 3.0 package were designed with the intention of improving performance of the WIMS-D code by providing an alternative to the very old standard multi-group constants library distributed with WIMS-D.
This version differs from the previous one in the following (includes 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.
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:
· iaea.lib - 69-group WIMSD-formatted library based on evaluated nuclear data files recommended by WLUP participants.
· iaeagx.lib - 172-group WIMSD-formatted library based on evaluated nuclear data files recommended by WLUP participants.

· jendl3gx.lib - 172-group WIMSD-formatted library based on JENDL-3.2 evaluated nuclear data files.
· jef22.lib - 69-group WIMSD-formatted library based on JEF-2.2 evaluated nuclear data files.
· jef22gx.lib - 172-group WIMSD-formatted library based on JEF-2.2 evaluated nuclear data files.
· jeff31.lib - 69 group WIMSD-formatted lib. Based on JEFF-3.1 evaluated nuclear data files
· jeff31gx.lib - 172 group WIMSD-formatted lib. Based on JEFF-3.1 evaluated nuclear data files
· Benchmarking results
· Documentation in electronic format
· Inputs files for NJOY and WILLIE
· Programs and batch procedures
· Dosimetry materials
· NRSC program for detailed resonance spectrum and Goldstein-Cohen parameter calc.
· XnWLUP package for plotting WIMS-D cross section data
· TRIGLAV package for TRIGA core benchmark calculation
The NJOY nuclear data processing system from Los Alamos National Laboratory was applied for generating the cross section files following models and conventions built into the WIMS-D lattice code. WLUP 3.0 libraries are based on recently released evaluated nuclear data libraries including JEFF-3.1, JEF-2.2, JENDL-3.2 and ENDF/B-VI Rev. 8.
