Division Spotlight
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

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.

Fast neutron bombardment of graphite displaces carbon atoms to interstitial positions and produces lattice vacancies. Upon heating the interstitial disturbances become mobile, move to more stable positions and release stored energy. The thermal release of stored energy was investigated by relative specific heat measurements, which are described in detail. Data are presented which show the dependence of energy storage upon extent of neutron bombardment and upon temperature of bombardment. Activation energy spectra for the thermal release of stored energy are calculated. The general trends of the data are discussed. Estimates are made of the numbers of interstitial carbon atoms, interstitial carbon (C2) molecules, and lattice vacancies in a sample of low bombardment. It is suggested that annealing of irradiated graphite causes much of the interstitial material to reintegrate with the graphite lattice by filling lattice vacancies.
