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.

Depletion perturbation theory was developed within the framework of an advanced hexagonal nodal diffusion method. A similarity transformation method was used to compute the mathematical generalized adjointsfrom the corresponding physical system because it was more convenient to utilize the numerical algorithms and codes developed for solving the real system equations. The methods were implemented using the DIF3D code for the flux solutions and were applied to a sample problem using a hexagonal geometry lattice. In all cases, there was good agreement between the results of direct subtraction and the depletion sensitivities. This work indicates it is feasible to generate depletion sensitivities within the framework of advanced nodal diffusion methods.
