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.

DTE Energy studying uprate at Fermi-2, considers Fermi-3’s prospects
DTE Energy, the owner of Fermi nuclear power plant in Michigan, is considering an extended uprate for Unit 2 that would increase its 1,100-MW generation capacity by 150 MW.

In the spherical-harmonics component form of the Boltzmann equation for a cylindrical system with radial symmetry and z-dependence, application of the commonly applied boundary conditions gives rise to more equations than there are unknowns. This paper considers selected combinations of the equations resulting from the application of these radial boundary conditions for the P3 approximation. Numerical evaluation of the angular flux at a free surface and at an interface between two different media shows that a combination of equations which closely satisfies the desired conditions is that suggested by Davison.
