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.

The total neutron cross section of 241Am was determined from transmission data obtained at the Lawrence Livermore Laboratory 100-MeV electron Linac for the neutron energy range from 0.5 to 25 MeV Neutron energies were measured using the time-of-flight technique. The transmission of a 12C sample was measured simultaneously to test the precision of this experiment. The measured 241Am cross section is compared with the evaluated data files, and discrepancies are noted.
