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.

State legislation: Delaware delving into nuclear energy possibilities
A bill that would create a nuclear energy task force in Delaware has passed the state Senate and is now being considered in the House of Representatives.

To renew a U.S. Nuclear Regulatory Commission (NRC) specific license for an independent spent fuel storage installation or a certificate of compliance for a dry storage system, the applicant must conduct an aging management review (AMR) that evaluates the potential aging-related degradation of those structures, systems, and components (SSCs) determined to be within the scope of renewal. Any credible aging mechanisms and effects identified for important-to-safety SSCs must be addressed in either time-limited aging analyses (TLAAs), if applicable, or aging management programs (AMPs). To improve the effectiveness and efficiency of the renewal process, the NRC is developing guidance for its staff in reviewing AMRs and AMPs—titled the Managing Aging Processes in Storage (MAPS) Report. The report generically evaluates potential aging mechanisms for storage system components, concluding whether or not the mechanisms could affect an important-to-safety function. Aging mechanisms are evaluated for (i) casks and internal components; (ii) neutron shielding; (iii) neutron poisons; (iv) concrete overpacks and support pads, and ceramic fiber insulation; and (v) spent fuel assemblies. The report provides aging management tables that identify the component-specific aging mechanisms and consequent effects that must be managed. Finally, the report describes example AMPs that include recommended prevention, mitigation, monitoring, and inspection activities.
