SCALE
TRITON - Multidimensional Transport
and Depletion Course
The
TRITON sequence in SCALE combines deterministic and Monte
Carlo capabilities into a multipurpose transport analysis tool. TRITON
can be
used to perform cross-section processing for a two-dimensional NEWT
transport
calculation. NEWT is an arbitrary-geometry, discrete ordinates
transport solver
that can be used for eigenvalue calculation, critical buckling
searches,
forward and adjoint flux solutions, cross-section weighting, collapse,
and
homogenization, and can be used to generate few-group constants for
lattice
physics calculations. Coupled with ORIGEN-S via TRITON, NEWT is most
often used
in 2-D depletion calculations. Such calculations can be used to
calculate
isotopic concentrations as a function of burnup, decay heat, neutron
and gamma,
source terms, radiotoxicity and dose estimates. Used in lattice physics
calculations, TRITON can be used to perform transport branch
calculations at
each depletion step, and to save lattice physics cross sections and
other
physics parameters for use in subsequent analysis. NEWT's
arbitrary-geometry capability
lends it to a wide variety of lattice analyses, including but not
limited to
PWR, BWR with control blades, VVER, and CANDU and ACR-700 designs.
Experienced
KENO-VI users will find that NEWT geometry input is based on that of
KENO-VI,
and exchanging (2-D)
models between the two codes is trivial. However, for some inherently
three-dimensional configurations, the 2-D solution of NEWT is
inadequate; in
such cases, the alternative is to use TRITON with KENO V.a or KENO-VI
as the
transport solver, to accommodate 3-D depletion.
This
course will teach attendees how to use NEWT for
transport calculations, and the use of TRITON for depletion
calculations. The
course will also instruct users on the use of KENO in place of NEWT for
Monte
Carlo-based depletion; however, attendees must be familiar with KENO
input, as
this is not covered within this course.
