Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

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.

A series of simple laboratory experiments was conducted to test the feasibility of separation of plutonium-contaminated soil into plutonium-rich and depleted fractions. The purpose of the separation is to reduce the costs of managing plutonium-contaminated soil by separating a large fraction of the soil that can be disposed of as noncontaminated soil. Water-scrubbing (agitation) and washing of a sample of soil from the Savannah River Plant burial ground separated out a clay-silt fraction containing ∼95% of the plutonium, but comprising only one-third of the total soil; the remaining two-thirds of the soil was a sand that contained only ∼5% of the total plutonium. The technique appears to be adaptable to commercial sand scrubbing and classifying equipment, and should be generally applicable to soils of high quartz sand content such as the clayey sands typical of the coastal plain of the southeastern United States, but verification with other soils will require similar laboratory tests.
