Argonne National Laboratory concluded a 14-year testing program at the Natural Convection Shutdown Heat Removal Test Facility to validate passive safety systems for advanced reactors. The generated datasets allow developers to verify modeling codes for decay heat removal without human intervention or external power. These results support the design and licensing of Generation IV reactors by providing empirical data on air and water-based cooling systems.

Earlier this year, researchers at Argonne National Laboratory (ANL) in Illinois completed a 14-year campaign to help inform the safety features of new advanced reactor designs.

The team performed an exhaustive list of experiments that successfully generated information developers can use to validate modeling codes and increase confidence in the safety calculations for new reactor concepts.
