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 erosion of carbon deposition layers by oxygen exposure and the desorpstion of hydrogen retained in the layers were investigated experimentally. Carbon deposition layers were formed by a sputtering method using hydrogen RF plasma. The layers were exposed to an argon gas with oxygen of 1013 Pa in the temperature range of 200-400°C. The erosion reaction progressed quickly within 10 minutes and then decelerated rapidly. The measurement of the outlet concentration revealed that most of the layer was eroded not as carbon monoxide and carbon dioxide but as soot. Additionally, it was estimated that the soot was released from the carbon deposition layer with a large amount of hydrogen.
