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.

Measurements of the flow velocity and direction in wire-spaced rod bundles were performed in air flow with a 37-rod subassembly that consisted of rods 31.6 mm in diameter, 3464 mm long, 6.0 mm in spacer wire diameter, and 1100 mm in wire wrapping pitch. The fine flow velocity and its direction were measured in both interior and wall subchannels in two sections of axial direction. Circular flow and decrease of axial flow velocity were observed in the subchannel containing the spacer wire. The variation of the transverse flow rate within one spacing wire pitch, which occurred between two adjacent subchannels, was obtained from the measured value to develop the computer program for the subchannel analysis.
