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.

Webinar: MC&A and safety in advanced reactors in focus
Towell
Russell
Prasad
The American Nuclear Society’s Nuclear Nonproliferation Policy Division recently hosted a webinar on updating material control and accounting (MC&A) and security regulations for the evolving field of advanced reactors.
Moderator Shikha Prasad (CEO, Srijan LLC) was joined by two presenters, John Russell and Lester Towell, who looked at how regulations that were historically developed for traditional light water reactors will apply to the next generation of nuclear technology and what changes need to be made.

Electron Bernstein waves (EBWs) have been confirmed as a suitable choice for plasma heating and current drive generation (electron Bernstein current drive) at densities where the O and X modes find cutoff values. In the present work, an estimation of the efficiency function of current generated for a relativistic distribution function is presented. The arbitrary large values of the refractive index, due to the EBW propagation properties, have also made necessary the expansion of our calculation up to any Larmor radius order. Particle trapping has been included considering the Okhawa effect, and the fractions of power absorbed by trapped and circulating particles separately have been estimated. Future work toward implementation of this method to the ray-tracing code used for realistic TJ-II ray trajectories (TRUBA) is also discussed.
