Computational Nuclear Physics |
This page provides nuclear data, physics simulations, and data
processing tools available for download and is hosted by
the Computational Nuclear Physics Group (CNP)
at Lawrence Livermore National Laboratory.
Generalized Nuclear Data (GND) format source code available from:
ENDF/B-VII.1 library is available in GND format
Nuclear Data
The CNP group collects and
evaluates experimental data and theoretical calculations produced at LLNL
and around the world. The results are then organized into databases that
are used as inputs to simulations. Tools are also provided that enable
users to interactively modify the data for sensitivity and uncertainty
studies. Nuclear data can be interactively viewed using
NADS.
Data Processing
The CNP group processes the
databases into tailored formats to increase the efficiency of laboratory
simulation codes. Support is provided for thermonuclear reaction rates,
Monte Carlo particle transport and deterministic particle transport.
Methods R&D
The CNP group develops new
computational techniques to improve the performance of particle and radiation
transport codes. The group has efforts in Monte Carlo particle tracking,
radiation transport schemes and random number generators.
Physics Simulations
LLNL has developed self-contained physics simulations that can be
interfaced to any parent transport code. Currently we provide three
distinct simulation codes: cosmic-ray shower distributions near the
Earth's surface, gamma-ray source spectra from nuclear decay of aged
mixtures of radioisotopes, and discrete neutron and gamma-ray emission
from fission. We also provide interface examples for popular Monte Carlo
transport codes such as
MCNP,
MCNPX, and
Geant4.
