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.

General Atomics R&D team recognized for contributions to NIF’s fusion ignition
The National Ignition Facility (NIF) at Lawrence Livermore National Laboratory has achieved fusion ignition at least five times, each time by directing its 192 high-powered lasers on a capsule containing a tiny, 2-millimeter target filled with hydrogen fuel. Not every shot achieves ignition, however. Tiny imperfections in the targets can mean fizzle, not fusion. But each of the targets used in successful experiments to date have something in common: they were characterized and selected by the 4Pi Integrated Metrology System, a new measurement system developed by General Atomics. Now, the team behind that system is being recognized.
GA announced last week that its Metrology Research and Development team had won the 2024 "Team of the Year" R&D 100 Professional Award from R&D World. The magazine that each year announces the R&D 100 awards that have been dubbed the “Oscars of Innovation” also selects just one “Team of the Year” and announces that award together with four other professional awards.

An estimation of the production of long-lived radionuclides by neutron-induced reactions in potential fusion reactor materials is very important for the development of low-activation materials. Although some measured data of activation cross sections leading to long-lived radioactive nuclides are available, the development of a calculation capability is necessary to provide complete excitation functions of the reactions involved. Calculations are not generally effective when experimental data to determine the parameters used in the model calculation are limited. In the SINCROS-II system, the consistency of the method of calculation is respected, and the parameters used are cross-checked by the available experimental data and the systematic trend of the calculated results. Thus, the SINCROS-II is expected to predict the activation cross sections with good accuracy, even if the cross section is calculated for a radioactive target nucleus. As an example of the cross-section predictions, the activation cross-section calculations are presented up to 20 MeV for neutron-induced production of long-lived radioactive nuclides 60Co, 59Ni, 63Ni, 91Nb, 94Nb, 93Mo, 99Mo, 108mAg, 150mEu, 152Eu, 158Tb, and 186mRe.
