Three-dimensional
Monte Carlo radiation transport codes (such as MCNPX)
are extensively used for nuclear applications. In collaboration with SNL,
UW researchers have overcome a major limitation
in Monte Carlo-based transport,
allowing fully accurate 3-D modeling of complex devices by integrating the
CAD geometry directly with the MCNPX code. This approach enables replacing
the surfaces that define any complex 3-D geometry with a more precise CAD
representation. The first-ever 3-D nuclear results were recently reported
for the ARIES Compact Stellarator, which uses a very complex plasma shape
and surrounding regions. This calculation would have never been possible
for any stellarator device modeled with MCNPX alone. The importance of
this work has been recognized internationally, with the ITER international
team requesting specifically that we apply this technology to ITER. This
enabling technology offers new capabilities to the
national and international
fusion neutronics community, allowing fully accurate
3-D neutronics analysis
of complex devices directly from the CAD systems in much less time
than was previously possible.
