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.

Nuclear energy: enabling production of food, fiber, hydrocarbon biofuels, and negative carbon emissions
In the 1960s, Alvin Weinberg at Oak Ridge National Laboratory initiated a series of studies on nuclear agro-industrial complexes1 to address the needs of the world’s growing population. Agriculture was a central component of these studies, as it must be. Much of the emphasis was on desalination of seawater to provide fresh water for irrigation of crops. Remarkable advances have lowered the cost of desalination to make that option viable in countries like Israel. Later studies2 asked the question, are there sufficient minerals (potassium, phosphorous, copper, nickel, etc.) to enable a prosperous global society assuming sufficient nuclear energy? The answer was a qualified “yes,” with the caveat that mineral resources will limit some technological options. These studies were defined by the characteristic of looking across agricultural and industrial sectors to address multiple challenges using nuclear energy.

Organic liquid scintillators, such as EJ-309, are capable of detecting fast neutrons and discriminating gamma rays through pulse shape. Higher detection efficiency is a common objective for detector designs and research. This paper describes two methods to enhance fast neutron detection by increasing neutron collection and reducing gamma-ray interference. Neutron collection can be increased by using strong scattering material to reflect neutrons toward scintillators. Gamma-ray interference can be reduced by using heavy material to shield gamma rays; such a material could have a minimal impact on neutron detection because neutrons and gamma rays have different interaction cross sections. In this work, both effects were investigated, experimentally and by simulation. Using a graphite reflector with simple geometry, the fast neutron detection was measured to have an increase of 9%, and simulations predicted an approximately 50% increase for optimized geometry. Using a lead shielding of 8-mm thickness, the neutron detection with a Pu source was measured to have a factor of 2 increase. These methods could be useful when cost-effective and highly efficient fast neutron detection is desired.
