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.

WEST claims latest plasma confinement record
The French magnetic confinement fusion tokamak known as WEST maintained a plasma in February for more than 22 minutes—1,337 seconds, to be precise—and “smashed” the previous record plasma duration for a tokamak with a 25 percent improvement, according to the CEA, which operates the machine. The previous 1,006-second record was set by China’s EAST just a few weeks prior. Records are made to be broken, but this rapid progress illustrates a collective, global increase in plasma confinement expertise, aided by tungsten in key components.

Two in-pile transient experiments were performed in the TREAT Reactor Facility to investigate fuel-coolant interaction phenomena that might occur in a hypothetical prompt-burst disassembly accident involving extensive fuel vaporization in a nearly unvoided liquid-metal fast breeder reactor core. In these tests, a single fuel pin containing 28 g of UO2 was subjected to a self-limited 23-msec-period TREAT power excursion which deposited fission energy of 1700 cal/g of UO2 in the fuel. The pin was contained in an instrumented autoclave filled with stagnant sodium. Failure of the fuel pins occurred at a mean energy input of about 540 cal/g, corresponding to a UO2 vapor pressure of about 100 atm. Results of these tests indicated that no energetic fuel-coolant interaction was produced and that the measured transient pressures can be reasonably described by the time history of the fuel vapor pressure.
