Abstract
Building new fission reactors in the United States presents many tech-
nical and regulatory challenges. Chief among the technical challenges
is the need to share and present results from new high-fidelity, high-
performance simulations in an easily consumable way. Since modern
multi-scale, multi-physics simulations can generate petabytes of data, this
will require the development of new techniques and methods to reduce the
data to familiar quantities of interest with a more reasonable resolution
and size. Furthermore, some of the results from these simulations may
be new quantities for which visualization and analysis techniques are not
immediately available in the community and need to be developed.
This paper describes a new system for managing high-performance
simulation results in a domain-specific way that naturally exposes quanti-
ties of interest for light water and sodium-cooled fast reactors. It enables
easy qualitative and quantitative comparisons between simulation results
with a graphical user interface and cross-platform, multi-language input-
output libraries for use by developers to work with the data. An example
comparing results from two different simulation suites for a single assem-
bly in a light-water reactor is presented along with a detailed discussion
of the system’s requirements and design.
