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.

Four million nuclear jobs by 2050: Who will do them?
Industry leaders from around the globe met this month to discuss the talent development that will be necessary for the long-term success of the nuclear industry.
The International Conference on Nuclear Knowledge Management and Human Resources Development, hosted by the International Atomic Energy Agency, was held in Vienna earlier this month. Discussed there was the agency’s forecast for nuclear capacity to more than double—or hopefully triple—by 2050 and the requirement of more than four million professionals to support the industry.

In a final repository for spent nuclear fuel, the waste canister may be surrounded by some backfill. For low-permeability backfills, the transport of dissolved species such as corrosive agents for radionuclides leached after canister penetration is faster by diffusion than by flow. In fissured rock the migrating species will have a large cross-section area for transport while in the bulk of the backfill, but a very small area for transport at the mouth of the fissure. A somewhat idealized physical model has been used as a basis for a mathematical model that has been solved analytically. It shows the influence of fissure widths, backfill thickness, and distance between fissures. Some calculations are performed using some geometrical configurations of interest. They show that the influence of fissure width on the transport rate is small.
