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 properties of pyrolytic silicon carbide (SiC) that are important to its use in nuclear fuel particle coatings are reviewed. The structure of material deposited under different conditions varies in growth features and the constituent phases; the principal effects of neutron irradiation on the structure are to create point defect clusters at irradiation temperatures below ∼1000°C (1273 K) and voids above ∼1000°C (1273 K), with a concomitant volume expansion. The thermal conductivity is greatly reduced by neutron irradiation. Data are available for mechanical properties including Young’s modulus, flexural strength, biaxial strength, and creep. Some useful results have followed from application of the Weibull model to strength measurements. The strength of single-phase beta-SiC is barely affected by neutron irradiation, but the strength of material containing excess silicon may be seriously reduced after irradiation. SiC has excellent resistance to oxidation as long as a surface film of silica is maintained. Diffusion of fission products is generally very slow, but it may be increased by structural imperfections.
