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.

The main objectives of a TRISO treatment are to effectively breach and separate the carbon and SiC layers composing the TRISO particles. The reported technologies used to treat a spent TRISO fuel are almost identical, involving a final wet chemical process under which crushed TRISO fuel is processed to separate the coating layer fines from the kernel. Also, these processes are mainly powder processes with a secondary waste generation, and they require a corrosive solution as well as complex processing steps.Hence, two innovative processing concepts are proposed in this investigation; namely, a thermal shock and a pyrochemical process to breach the coating layers of the TRISO particle with a minimal amount of secondary waste. The preliminary results showed that the chemical vapor deposition (CVD) SiC layers, as pseudo coating layers of the TRISO fuel, exhibited very robust thermal shock behaviors even at 1300°C of T, but a cyclic thermal shock caused a drastic degradation of their hardness. Also, it was confirmed that the CVD SiC as well as the glassy carbon rod can be breached by a chemical reaction in a molten salt with Mg and Li, respectively. Therefore, the proposed technologies are found to be very promising for treating a spent TRISO fuel without a considerable generation of secondary wastes.
