Advanced Reactor Modeling Interface

Open-Source Software to Develop Next-Generation Clean Energy Technology

Since the beginning, TerraPower has hastened its pace of innovation with smart software design.

Recent efforts led developers to the open-source community to share and improve the collective knowledge of software tools for advanced reactor systems. Open-source software can help improve options for advanced reactor designs and to lay the foundation for a strong regulatory basis for new reactors.

TerraPower’s team joins developers of similar open-source software, such as INL’s MOOSE (Multiphysics Object-Oriented Simulation Environment), MIT’s OpenMOC, OpenMC and others, to work collaboratively with DOE and the nuclear industry in their efforts to develop and demonstrate advanced reactor technologies. The open-source portion of TerraPower’s software offers a framework and ecosystem that will benefit from external contributors who are also in need of better automation tools and expressive reactor frameworks.

With an open-source portion of TerraPower’s software, TerraPower’s advanced reactor modeling interface provides an integration platform that can improve the usability and coupling of physics kernels and reactor analysis methodologies, whether they be proprietary or publicly available.

Working with the Open-Source Community

We are excited to work with the broader open-source software community for the advancement of critical technology.

We believe our tools can also provide an answer…

to the industry’s quest for a system capable of confirmatory analyses supporting various advanced reactor concepts or designs.

TerraPower’s advanced reactor modeling interface software is complementary to the powerful proprietary physics kernels of the U.S. Department of Energy labs, TerraPower and other organizations, which users may obtain separately.

Together with these proprietary kernels, this platform allows engineering-level design and analysis of myriad different processes for generic reactor designs. It also exponentially reduces the amount of data management that needs to be done in the beginning stages for most companies. Design parameters must be provided by the user. This allows national laboratories, regulators, universities and reactor developers to evaluate concepts at much earlier stages of development.
