Both codes use ENDF/B-VII.1 cross sectiondata, but TRIPOLI-4® also uses cross section data basedon JEFF-3.1.1. The MAVRIC/Monaco simulations wereperformed with the SCALE 6.2.2 release while theTRIPOLI-4® simulations used an internal developmentversion of the code. For the most part, the simulated andmeasured neutron counts agree within 30%. Simulatedgamma flux data is compared, as well. There are nomeasured gamma data. The agreement between thesimulated gamma flux spectra is often within 10% or less,but there some notable differences, especially whencomparing simulations using ENDF/B-VII.1 and JEFF3.1.1 based cross section data. The comparison of photonsimulations suggests that improvements are needed in thecross-section data, cross section processing codes, and/ortransport codes and gamma measurement data is neededfor experimental validation. %G English %2 https://cea.hal.science/cea-02339097v2/document %2 https://cea.hal.science/cea-02339097v2/file/201800002069.pdf %L cea-02339097 %U https://cea.hal.science/cea-02339097 %~ CEA %~ DEN
