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.

Bacteria found to reduce uranium mobility in clay
Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) research laboratory in Germany have investigated a microorganism capable of transforming water-soluble hexavalent uranium [U(VI)] to the less-mobile tetravalent uranium [U(IV)]. The researchers found that the sulfate-reducing bacterium Desulfosporosinus hippei, a relative of naturally occurring microorganisms present in clay rock and bentonite, showed a relatively fast removal of uranium from clay pore water.

Radiation effects and shield requirements are analyzed for the MARS axicell region. Dominant coil life limiting effects in the normal insert coils are found to be swelling in the spinel insulation and resistivity changes of the conductor due to transmutations. The shield between the insert and superconducting coils is optimized and reduces all radiation responses to acceptable levels. However, streaming in the neutral beam duct resulted in an unacceptable dpa rate in the Cu stabilizer and has resulted in a redesign of this region without a neutral beam and with a single insert coil.
