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.

Argonne’s METL gears up to test more sodium fast reactor components
Argonne National Laboratory has successfully swapped out an aging cold trap in the sodium test loop called METL (Mechanisms Engineering Test Loop), the Department of Energy announced April 23. The upgrade is the first of its kind in the United States in more than 30 years, according to the DOE, and will help test components and operations for the sodium-cooled fast reactors being developed now.

Neutron activation measurements are reported for 44 reactions from 14 materials irradiated in a well-characterized neutron field produced by 40-MeV deuterons impinging on 9Be at the Oak Ridge Isochronous Cyclotron. Foil packets were located at 0 and 15 deg to the beam at 7.62 cm from the source, and additional foil materials were located directly on the deuteron beam stop 6.25 mm from the source. Integral tests were made for 30 reactions using previously measured time-of-flight (TOF) spectra and neutron cross sections, primarily from ENDF/B-IV, extrapolated to 44 MeV. The integral results are excellent, with an overall standard deviation of ±11% for 25 recommended reactions (±14% for 30 reactions), and neutron spectra unfolded with the SAND II code show excellent agreement with TOF measurements.
