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.

Candidates for leadership provide statements: ANS Board of Directors
With the annual ANS election right around the corner, American Nuclear Society members will be going to the polls to vote for a vice president/president-elect, treasurer, and members-at-large for the Board of Directors. In January, Nuclear News published statements from candidates for vice president/president-elect and treasurer. This month, we are featuring statements from each nominee for the Board of Directors.

Experiments have been performed on the pressure drop of a spacer grid in rod bundles of 12 rods. Both smooth and rough rod bundles were used in the experiments. The artificial roughness cut into the outer surface of the rods was chosen so as to meet the actual design of a gas-cooled fast breeder reactor. The results of this investigation for a Reynolds number range between Re = 4 × 103 and 7 × 104 indicate that the pressure drop at the spacer grids is higher in a roughened rod bundle than in a smooth rod bundle.
