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 dynamic behavior of the failed steam generator tube plug of an operational plant in 1989 can be understood through an analysis that solves the energy equation of the broken plug top and computes its kinetic energy as a function of elevation in the tube. The computed high kinetic energy of the plug top when it reaches the U-bend of the tube can exceed the work required to penetrate the tube wall at that location. If the inlet flow area at the bottom of the tube is small, the plug top exhibits an interesting stop-and-reacceleration behavior.
