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.

Nuclear supply chain innovation and collaboration: Keeping the nuclear supply chain viable through change
The next nuclear renaissance may be upon us, but with it comes a perfect storm. The industry is unprepared for a surge in demand for goods and services from both the existing light water fleet and the next generation of reactors. We are currently teetering on the edge of severe supply chain issues, but if the nuclear industry can understand the sources of our challenges, we can mitigate them.

A review on the plasma position and current control system for the JT-60 upgrade is presented. In the control system, advanced digital technologies such as the versa module Europe bus, the computer automated measurement and control technology, and Ethernet are applied to fast equilibrium control of the vertically elongated divertor plasmas. The delay of the overall feedback loop with a sampling period of 0.25 ms is <1.3 ms, including the delay of the power supply for the horizontal field coil. Multivariable control with matrix gain has been adopted in the system for decoupling control of the equilibrium parameters such as the plasma current and the horizontal position. The idea of an "algorithm number preprogram" was newly introduced into the control system for more flexible control. This made it possible to dynamically switch the control algorithms at any time of plasma pulse discharge. Several experiences in plasma control are presented. The development of a real-time plasma shape visualization system for advanced monitoring and control is also described.
