Horizontal Refueling and Remote Handling Design Review

The Remote Systems Group (RSG) at Oak Ridge National Laboratory (ORNL) will perform a three-stage design review focused on operations, the detailed design, and a failure modes and effects analysis. Their experience base is uniquely valuable to MIGHTR and In-Vesel Fuel Handling Machine (IVFHM) development. This project will mitigate the risk of operational complexity by reviewing a critical system.

Improvements to Passive Heat Removal Systems in SAS4A/SASSYS-1

For this project, ARC will work with Argonne National Laboratory (ANL) to enhance the SAS modeling capabilities for passive heat removal systems, including the generic RVACS model and the DRACS heat exchanger models. These enhancements will enable ARC to recover safety margins and have a better representation of the system’s response during long-term cooling events.
