ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

Uranium prices boosted through May’s end
Uranium futures rose to $71.90 per pound on June 2, according to online analysis firm Trading Economics. That price was near its highest level since early February—in contrast to an 18-month low in prices reached in mid-March.

The hydrogenated terphenyl mixture HB-40, which is of interest as a reactor coolant, has been irradiated in a loop in the NRX reactor under conditions simulating those that might pertain in an organic-cooled reactor. High Boiler decomposition products were removed by distillation and the recovered coolant was recycled to attain a stationary-state composition. Irradiation temperatures ranged from 250 to 375°C. Rates of coolant consumption and properties of the partly decomposed coolant mixture were determined. These are compared with the properties of the terphenyl coolant mixture, Santowax OM, irradiated under the same conditions. Important differences were noted between the properties of the stationary-state coolant mixtures and the properties of the starting materials. The HB-40 mixture appears suitable for use as a reactor coolant at temperatures up to at least 375°C. It has the advantage of remaining liquid under all conditions of use.
