A compelling
need exists for the development of accurate and efficient reactor physics
simulation tools in the analysis of currently operational nuclear reactors, and
in the design of next generation reactor concepts. More accurate simulation methods can improve
safety and reliability, shorten the development cycle of next generation
reactors, and lead to the design of reactors with improved efficiency, safety,
and reliability. This project will
develop an intuitive, fast, and accurate reactor physics simulation tool that
is compatible with established computer aided design (CAD) and computer aided
engineering (CAE) practices. It is based
on the application of a novel deterministic solver, which has been shown to
provide a favorable combination of accuracy and speed for a broad range of
simulations. Phase I involved the
development and verification of a proof-of-concept reactor modeling
process. Both steady-state and
time-dependent simulations were run, and the results were compared to
experimental data. The accuracy and
efficiency of the solutions verified the feasibility of the approach. Phase II will focus on the development and
testing of enhancements that can improve efficiency, accuracy and ease-of-use
for the analysis of both commercial and research/test reactors. In particular, solver and model generation
enhancements will be incorporated, a graphical user interface will be developed,
cross section and thermal-hydraulics integration will be provided, and source
generation routines will be developed.
Commercial Applications and Other Benefits as described by the awardee: By reducing uncertainties associated with design and operation, the new simulation tool should help improve the safety and efficiency of a broad range of reactor types, including reactors for commercial power, research, isotope production, and naval and space propulsion.
