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
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

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.

In the Tohoku University Heliac (TU-Heliac), hot-cathode biasing experiment has been carried out. Poloidal Mach number exceeded unity, and reached 5 (supersonic regime). Increase of the electron density and decrease of the impurity influx were observed. It is important to study the anomalous transport for evaluation of the improvement. Then potential and density fluctuation (~600 kHz) measurement system were installed to the TU-Heliac. Characteristics of the fluctuations in the hot-cathode-biased supersonic plasma were measured. The fluctuation of (i) low frequency band (<10 kHz) and (ii) high frequency band (100~300 kHz) had large power spectra. The fluctuations between these bands (10~100 kHz) were suppressed. The potential fluctuation level was larger more than one order of the density fluctuation level in the low frequency band (<10 kHz), and comparable to the density fluctuation level in the high frequency band (100~300 kHz).
