Integration Product Line

The NEAMS program is organized along three product lines: the Fuels Product Line (FPL), the Reactors Product Line (RPL) and the Integration Product Line (IPL).
NEAMS FPL and RPL provide many advanced tools, such as the BISON and MARMOT fuel performance tools based on the Multiphysics Object-Oriented Simulation Environment (MOOSE) from Idaho National Laboratory and the PROTEUS neutronics code and the NEK5000 computational fluid dynamics code from the Simulation-based High-efficiency Advanced Reactor Prototyping (SHARP) tools from Argonne National Laboratory. However, these advanced tools often require large computational resources, can be difficult to install, and require expert knowledge to operate, causing many analysts to continue to use traditional tools instead of exploring high-fidelity simulations.


The NEAMS IPL is responding to the needs of design and analysis communities by integrating robust multiphysics capabilities and current production tools in an easy-to-use common analysis environment that enables end users to apply high-fidelity simulations to inform lower-order models for the design, analysis, and licensing of advanced nuclear systems.

 

NEAMS Workbench

NEAMS Workbench.pngThe NEAMS Workbench is a new initiative that will facilitate the transition from conventional tools to high-fidelity tools by providing a common user interface for model creation, review, execution, output review, and visualization for integrated codes. The Workbench can use common user input that includes engineering scale specifications that are expanded into application-specific input requirements through the use of customizable templates. The templating process enables multi-fidelity analysis of a system from a common set of input data. Expansion of the codes and application templates available in the Workbench will broaden the NEAMS user community and will facilitate system analysis and design. Users of the Workbench will still need to license and install the desired computational tools, but it will provide a more consistent user experience and ease the transition from one tool to the next.

 

 

Multiphysics Integration

TIntegration tools Workbench.pnghe BISON fuel performance tool provides many predictive capabilities, but relies on simplified power distribution, burnup, and coolant models, which are not predictive of the true performance of the fuel. The Warthog tool is integrating predictive power distributions from PROTEUS with burnup data from ORIGEN and thermal hydraulic capabilities from Nek5000 to enhance the predictive capabilities of BISON for a variety of fuel types.
