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.

Teenager’s school project achieves plasma
Cesare Mencarini’s recent extended project qualification (EPQ) earned him an “A” for his studies in the United Kingdom—and became, it is believed, to be the first nuclear reactor built in a school environment.

Fractional release rates of relatively low volatility fission products from fuel have been measured at the Sascha facility at Karlsruhe, Federal Republic of Germany, and elsewhere as a function of fuel temperature. A mass transfer model was developed to calculate these release rates. Of six materials (fission products or fission product oxides) analyzed at temperatures from 1800 to 2400°C, favorable comparisons between experiments and theory were obtained for silver, antimony, ruthenium, BaO, and ZrO2, while insufficient experimental data were available for SrO. The favorable comparison for the five materials provides a strong argument that vaporization mass transfer is controlling the release rate for certain low-volatility fission products.
