ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

We review some of the theoretical interpretations which have been given for the formation of the high E→r x B→ rotation shear layer observed concomitantly with the transition to and the operation in the high confinement mode. Those can be classified as follows: the origin of the large radial electric field is (i) anomalous, (ii) associated with loss of ions along open orbits (i.e. crossing the separatrix), (iii) related to the decoupling of the ion and electron flows by finite Larmor radius effects and inertia. It is generally accepted that E→r x B→ shear reduces the level of microturbulence and thus of anomalous transport; this point of view is adopted here and explained.
