The objective of this project is to assess the RELAP5- 3D code for application to the MSRR design and licensing pathway to resolve data limitations for both the input models for the plant design and models specific to the liquid fuel molten salt core.
The objective of this project is to use Large Eddy Simulations (LES) to produce numerical benchmark data that captures local velocity and temperature effects, and this data will have an immediate impact to accelerate technology development, enable economic optimization, and reduce regulatory uncertainty.
The objective of this project was to exact high quality, traceable data that quantifies composition dependencies and measurement uncertainty to inform operating conditions, which is paramount for proper design in any reactor, especially a liquid-fueled molten salt reactor.

The objective of this project was to analyze reactor core and system behavior in response to anticipated transients and accident scenarios and to use the Virtual Environment for Reactor Applications (VERA) code suite, which employs multi-physics simulation to model feedback behavior in the reactor core.
June 15, 2020 – The DOE has recently completed its work with industry stakeholders in support of the advanced reactor Licensing Modernization Project (LMP). This project was led by Southern Company (on behalf of industry), coordinated through the Nuclear Energy Institute (NEI), and cost-shared by DOE.
