3. DESCRIPTION OF PROGRAM OR FUNCTION

UTXS is a continuous-energy cross section libraries in ACE format suitable for the MCNP code were generated using the NJOY94.105 processing code. Libraries for various materials were generated at typical operating temperatures of Pressurized Water Reactor (PWR), Boiling Water Reactor (BWR), and the Russian PWR (VVER) as well as libraries for other non-reactor applications such as nuclear medicine.

4. METHOD

The need for cross section libraries for various materials at different temperatures arose during the benchmark activities related to mixed oxide fuel (MOX) utilization in existing light water reactors. The current version, UTXS6, is based on ENDF/B-VI except for Zinc and Erbium for which the Russian (BROND-2) and the Chinese (CENDL-2) libraries were used.

The UTXS6 library went through preliminary testing and validation. The validation process consisted of three steps: checking the library structure, plotting comparison with standard cross sections from Los Alamos National Laboratory, and benchmarking against ENDF60 and experimental data.

The UTXS6 library was benchmarked against ENDF60 and experimental data for some nuclides. Experiments from the "International Handbook of Evaluated Criticality Safety Benchmark Experiments" (NEA/NSC/DOC(95) 1997) were used along with MCNP input files supplied with the electronic copy. Benchmark calculations were done with MCNP4B on SUN workstation.
