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.

Why should safeguards by design be a global effort?
Jeremy Whitlock
I can’t think of a more exciting time to be working in nuclear, with the diversity of advanced reactor development and increasing global support for nuclear in sustainable energy planning. But we can’t lose sight of the need to plan for efficient international safeguards at the same time.
Global nuclear deployment has been underpinned since 1970 by the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), making it a key customer requirement for governments to demonstrate unequivocally that the technology is not being misused for weapons development.
The International Atomic Energy Agency (IAEA) has helped verify this commitment for more than 50 years, but it has never safeguarded many of the advanced reactors (and related fuel cycle processes) being developed today.

Heliotron reactors have several features suitable for a fusion power plant, such as no need for current drive, no plasma current disruptions, suitability for steady-state operation, and a wide space between helical coils useful for maintenance of in-vessel components. According to recent reactor studies based on the experimental results in the Large Helical Device (LHD), the plasma major radius of a heliotron reactor is set to 14 to 16 m in order to install shielding and breeding blankets with total thickness of 1 m. The central toroidal field for the self-ignition is 5 to 6 T under the assumption that the confinement enhancement factor is 1.2 to 1.4 with respect to the LHD. The stored magnetic energy is estimated to be 120 to 150 GJ. Both the major radius and the magnetic energy are three times larger than those of ITER. Its large helical windings, however, can be realized by steady extension from the ITER technology, because cable-in-conduit conductors similar to those for ITER toroidal field coils can be adopted. Improvement of plasma confinement is essential to reduce the number of magnet systems. A roadmap to a heliotron DEMO is discussed.
