3. Computational analysis management. The integrated modeling simulation process management
system includes: storing relevant simulation data; transmitting them to multiple solvers in
an appropriate format; and making the results available for post-processing, visualization and debugging
utilities. a multi-physics integration arises from the ability to perform all analyses on geometric
models derived from an identical representation, i.e., the computer-aided design (cad)based
solid model. This common domain representation points to a strategy for expanded multiphysics
applications where the internal representation of the geometry is common across the simulation
tools.
4. Verification and validation. The integrated model development must reflect true plasma
chamber system behavior. model validation will arise from comparison with the existing experimental
data, particularly data from experiments that address multiple effect and material interaction
tests. during the iteR construction phase, the integrated model could be heavily utilized
for mock-up and tbm designs. Ultimately, this integrated simulation tool, strongly benchmarked
with the experimental data obtained from the “real fusion environment” on iteR and
FnsF (component test Facility), will evolve to a validated predictive capability for demo.
Scale and Readiness
aRies forms the basis and starting point for the integrated design activities for future magnetic
fusion energy power plants, although no specific activity related to demo has been commissioned.
more extensive design activities could be initiated at any time. The scope and level of effort
should be expanded to approximately $10m per year as the demo design activities progress
from conceptual design, to a more comprehensive integrated design effort including detailed
Rami, safety and environmental aspects. This level of effort is needed to more fully engage the
broad spectrum of expertise required to carry out such detailed activities.
The effort to develop an integration model coupled with a computer-based geometric component
has begun. Preliminary work involving coupling neutronics and thermo-fluids analysis codes
based on a common cad model, has been applied to the Us iteR first wall/shielding blanket design.
however, a focused effort of the development of an integrated model for fusion chamber
specific research is yet to be initiated. development of mature fusion specific physics models and
code integration tasks would initially require funding at the level of $1-2m. collaboration with
the experts in the areas of computer science and applied mathematics from the FsP team would
provide consistent, convergent, accurate solutions to the coupled multi-physical problems. as the
project progresses, efforts should expand to produce experimental data for code validation.
benefits of integrated Designs and Models
development of effective fusion power is a cost-intensive process, fraught with many compounded
complexities and increasingly expensive experiments and test facilities. any experiment or facility
failure would be very costly to the fusion program. Thus, major failure risks must be aggressively
mitigated. These integrated models and designs offer a cost-effective risk-mitigation option
for the fusion program at a fraction of the cost of a single facility or experiment. it also enables a
wide range of design exploration and optimization over a broad spectrum of options and configurations.
once an acceptable approach is selected, these tools will allow fine-tuning of the design
and processes necessary to effectively design, build, and operate demo. additional benefits are
