ANS designates Armour Research Foundation Reactor as Nuclear Historic Landmark
The American Nuclear Society presented the Illinois Institute of Technology with a plaque last week to officially designate the Armour Research Foundation Reactor a Nuclear Historic Landmark, following the Society’s decision to confer the status onto the reactor in September 2024.

The Flowing Liquid Surface Retention Experiment (FLIRE) has been built and designed at the University of Illinois at Urbana-Champaign to provide fundamental experimental data on the retention and pumping of He, H and other species in flowing liquid surfaces. These measurements are critical to the development of advanced plasma-facing components (PFCs) that apply flowing liquid metals to mitigate high heat loads encountered in the divertor region of next-step fusion reactors. The FLIRE facility currently uses an ion beam source, which injects ions into a flowing stream of liquid lithium. Its design allows the liquid lithium to flow between two vacuum chambers that become isolated from each other when the lithium flows. Recent results show retention of helium in flowing liquid lithium at 250-300 °C to be of the order 10-4 and diffusivities of 10-4 to 10-3 cm2/sec.
