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.

Disney World should have gone nuclear
There is extra significance to the American Nuclear Society holding its annual meeting in Orlando, Florida, this past week. That’s because in 1967, the state of Florida passed a law allowing Disney World to build a nuclear power plant.

Theoretical and experimental work on the vertical position control system on the COMPASS-D tokamak is described. An analog proportional + derivative (P + D) system is currently used, and two important sources of disturbance are observed in the system. One source is 600-Hz noise from thyristor power supplies, and the other is impulselike disturbances due to edge-localized modes (ELMs). A high-order controller is developed using the [script H] technique to reduce the effect of the 600-Hz noise. This initial design is based on a model of the plasma position system obtained from system identification. The controller is implemented on a digital signal processor and tested on COMPASS-D. The controller synthesis procedure and the experimental results are presented. Large, separated ELMs on COMPASS-D cause impulselike responses to be observed in the power amplifier and position signals. Closed formulas are given for the minimum possible peak of the impulse response of the system, which is used to find the limit of performance.
