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.

The distribution function of fast alpha particles in a tokamak plasma near the outer circumference of the torus is obtained. Calculations are carried out for an axisymmetric tokamak for which the alpha-particle banana width is small in comparison with the plasma radius but sufficiently large to provide the presence of trapped alpha particles, produced in the plasma core, in the plasma edge region. It is shown that alpha particles with this distribution function can excite an edge-localized instability of plasma on magnetoacoustic waves with a frequency close to the harmonics of the alpha-particle gyrofrequency. This contributes to an explanation of the superthermal ion-cyclotron emission observed experimentally on the Joint European Torus (JET) and the Tokamak Fusion Test Reactor (TFTR).
