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.

Price: $49
Organizer: William Dawn (Studsvik)
Peacock is a three-dimensional, continuous-energy, Monte Carlo code developed by Studsvik Scandpower, Inc. (SSP). Peacock is intended to augment the current offerings from SSP to model advanced, next-generation nuclear reactors. The code allows modeling of general geometries and includes capabilities for depletion. Peacock is designed for efficient use on commonly available, consumer-grade computing architectures and includes shared-memory (OpenMP) parallelism.
In addition to a presentation on the theoretical foundations of the Peacock methodologies, attendees will be running Peacock cases. By running Peacock, attendees will be able to investigate reactor physics phenomena (e.g., temperature dependences, depletion, etc.). Participants will need to bring their own laptop with a ssh client to access the Peacock computing resources that will be furnished by SSP.
No licensing is required as no code or executables will be provided to attendees. Attendees will only be able to run Peacock on resources provided by SSP.
