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.

Taking shape: Fusion energy ecosystems built with public-private partnerships
It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.
Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.

Confocal micro X-ray fluorescence (confocal MXRF) is continuing to be explored as a method for characterizing copper and argon doped sputtered beryllium capsules. Previously demonstrated was the utility of confocal MXRF in both the two- and three-dimensional modes and overlaying the data with X-ray micro computed tomography as a method of nondestructive analysis. In this paper, the relative amount of copper dopant was measured as a function of capsule theta, examining the changes in the amounts of copper around the circumference of the capsule and comparing the relative amount of copper between capsules. A theta stage was specially constructed in order to perform line scans through the capsule wall while keeping the geometry of the measurement constant. Four capsules (one unpyrolyzed and three pyrolyzed) were examined with this method. The noise of the measurements averaged 1.43%, and differences within a capsule as a function of theta were 2.15%, with differences between capsules [approximately]13% indicating that the measurement noise was approximately half the overall variation in copper signal and far less than the measured differences between capsules. These differences in the amount of copper within a capsule and between capsules are much greater than that obtained using absorption techniques.
