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.

Digital control system installed at China’s Linglong One
Earlier this month, the first digital control system was put in place at Linglong One, a small modular reactor demonstration project being built at the Changjiang nuclear power plant in Hainan Province. This is the world’s first land-based commercial SMR and is controlled by China National Nuclear Power Co. Ltd., a subsidiary of the China National Nuclear Corporation (CNNC).

The non-uniqueness of solutions of the nonlinear integral equations for the generalized Chandrasekhar′s function and H matrix for a homogeneous halfspace is discussed, and a new uniquely soluble equation for the H matrix is constructed. Then the complete solutions for the half-space albedo and Milne problems for thermal neutrons with the isotropic scattering degenerate kernel are derived. The solutions are expanded in terms of the infinite medium eigenfunctions and the expansion coefficients are determined from the corresponding emergent distributions, which have been discussed in an earlier paper and expressed in terms of the H matrix. In solving the albedo problem, the half-range completeness of the eigenfunctions is demonstrated and the corresponding halfrange closure relation is derived. At the end, numerical results for the heavy gas scattering model are presented.
