MCNP™ Version 5

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2004
Abstract The Monte Carlo transport workhorse, MCNP [Los Alamos National Laboratory report LA-13709-M, 2000], is undergoing a massive renovation at Los Alamos National Laboratory (LANL) in support of the Eolus Project of the Advanced Simulation and Computing (ASCI) Program.

The comparison of MCNP perturbation technique with MCNP difference method in critical calculation

Nuclear Engineering and Design, 2010
Abstract For a nuclear fission system, we calculated Δkeff, which arise from system material composition changes, by two different approaches, the MCNP perturbation technique and the MCNP difference method. For every material composition change, we made four different runs, each run with different cycles or each cycle generating different neutrons ...

Nuclear data for MCNP

2006
The sources of neutron and photon transport data are described as well as the processing of the evaluated data sets into continuous-energy and multigroup cross-section sets. The procedures for checking and validating the processed data are discussed. The question of why so many data sets are available is addressed by indicating the differences between ...

Present and future capabilities of MCNP

Applied Radiation and Isotopes, 2000
Several new capabilities have been added to MCNP4C including: (1) macrobody surfaces; (2) the superimposed mesh importance functions, so that it is no longer necessary to subdivide geometries for variance reduction; and (3) Xlib graphics and DVF Fortran 90 for PCs.

Defining MCNP Sources in Moritz

Nuclear Technology, 2009
We have added a source definition component to the Moritz geometry editing and display program. Gamma line emission can be imported from a library based on the Brookhaven National Laboratory Nuclear Data Center. The user can select one or more isotopes from a tree view list. The abundances can be corrected for radioactive decay between two times.
