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.

Neutron transmission measurements of U233 and U235 have been obtained from 0.02 to 0.08 ev. The 2200 m/sec total neutron cross section values have been calculated from a linear least-squares fit to the data in this region and found to be 587 ± 6 and 690 ±10 barns, respectively. The data were taken with the Materials Testing Reactor (MTR) fast chopper with an instrument resolution of 2 µsec/m. Experimental techniques, involving the use of a 1024-channel time-of-flight analyzer for measuring total cross sections at low energies, are described.
