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.

To study the application of laser Raman spectroscopy to analysis fusion fuel processing gas, six hydrogen isotopes were experimentally measured. Raman spectra of these mixture gases showed that the useful lines for quantitative analysis are Stokes rotations below 1000 cm−1, with representative lines for H2, HD, D2, HT, DT and T2 being 587, 443, 415, 395, 250 and 200 cm−1 respectively. The absolute Raman intensity ratio was estimated as H2:HD:D2:HT:DT:T2 = 100:58:47:46:36:41. With the laser wavelength of 488 nm, power of 700 mW and using a multiple pass system, the detection limit for H2 was 10 Pa, which was the equivalent of 100 ppm in concentration. As a remote sensing technology, the optical fiber was verified as applicable for transferring the irradiation laser beam.
