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.

Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

The ablation of first surface materials by x rays is a primary threat to the final optics in the NIF target chamber. To meet the operational goals of the facility, the designs of the chamber wall, target holder, and diagnostic surfaces must minimize ablation by x rays, typically by specifying materials that are low-Z, high temperature resistant, and shock resistant. Additionally, the response of the optics to direct target emissions must be understood. This paper describes some experimental and modeling work to develop the validated computer models necessary to quantify the x-ray response of various materials. These codes and further experiments will then confirm the ability of NIF first surface designs to meet functional requirements.
