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
Nuclear Nonproliferation Policy
The mission of the Nuclear Nonproliferation Policy Division (NNPD) is to promote the peaceful use of nuclear technology while simultaneously preventing the diversion and misuse of nuclear material and technology through appropriate safeguards and security, and promotion of nuclear nonproliferation policies. To achieve this mission, the objectives of the NNPD are to: Promote policy that discourages the proliferation of nuclear technology and material to inappropriate entities. Provide information to ANS members, the technical community at large, opinion leaders, and decision makers to improve their understanding of nuclear nonproliferation issues. Become a recognized technical resource on nuclear nonproliferation, safeguards, and security issues. Serve as the integration and coordination body for nuclear nonproliferation activities for the ANS. Work cooperatively with other ANS divisions to achieve these objective nonproliferation policies.

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.

Radial potential profiles are precisely controlled to vary both radial electric field Er and its shear by using a 10-segmented endplate in an ECR-produced plasma. Observed frequencies and intensities of flute-mode and drift-mode fluctuations depend on the potential profile. The frequencies are Doppler shifted by E × B drift. The flute-mode fluctuation is identified as Kelvin-Helmholtz type instability which is destabilized by strong E × B flow shear. The drift-mode fluctuation is destabilized in the region of small and negative electric field. When the E × B rotation frequency shear is increased with Er being fixed, the drift-mode fluctuations increase once in a weaker shear region, attain its peak at a certain shear and then decrease in the strong shear region. This behavior suggests that the rotation frequency shear of net ion drift which is determined from both E × B drift and diamagnetic drift is important for stabilizing the drift mode.
