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
Isotopes & Radiation
Members are devoted to applying nuclear science and engineering technologies involving isotopes, radiation applications, and associated equipment in scientific research, development, and industrial processes. Their interests lie primarily in education, industrial uses, biology, medicine, and health physics. Division committees include Analytical Applications of Isotopes and Radiation, Biology and Medicine, Radiation Applications, Radiation Sources and Detection, and Thermal Power Sources.

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.

A pebble divertor concept is to use the flow of multi layer pebbles as plasma facing component In the divertor plasma, the falling behavior of pebbles is affected by various forces: electromagnetic force, electrostatic force, plasma static pressure and plasma momentum flux. The forces against pebbles in divertor plasma are calculated by referring the edge modeling result of an ITER CDA type divertor. The result of the calculation is that the behavior of pebbles is dominantly affected by the plasma momentum flux. The influence of the electromagnetic force, the electrostatic force and the plasma static pressure can be negligible.
