Comparison of MAVRIC/Monaco and TRIPOLI-4 Simulations of the LLNL Pulsed Spheres Benchmark Experiments
Abstract
Simulations of the Lawrence Livermore Pulsed
Spheres with MAVRIC/Monaco and TRIPOLI-4® are
presented. Both codes use ENDF/B-VII.1 cross section
data, but TRIPOLI-4® also uses cross section data based
on JEFF-3.1.1. The MAVRIC/Monaco simulations were
performed with the SCALE 6.2.2 release while the
TRIPOLI-4® simulations used an internal development
version of the code. For the most part, the simulated and
measured neutron counts agree within 30%. Simulated
gamma flux data is compared, as well. There are no
measured gamma data. The agreement between the
simulated gamma flux spectra is often within 10% or less,
but there some notable differences, especially when
comparing simulations using ENDF/B-VII.1 and JEFF
3.1.1 based cross section data. The comparison of photon
simulations suggests that improvements are needed in the
cross-section data, cross section processing codes, and/or
transport codes and gamma measurement data is needed
for experimental validation.
