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.

Securing the advanced reactor fleet
Physical protection accounts for a significant portion of a nuclear power plant’s operational costs. As the U.S. moves toward smaller and safer advanced reactors, similar protection strategies could prove cost prohibitive. For tomorrow’s small modular reactors and microreactors, security costs must remain appropriate to the size of the reactor for economical operation.

Low-frequency fluctuations related with a radial electric field are investigated in a magnetized plasma column produced by the electron cyclotron resonance. Various radial profiles of space potential are formed by biasing a segmented endplate. Radial electric field and its shear are obtained by fitting the 6th order polynomials to the potential profiles measured. Two types of fluctuations are observed in this experiment. The flute mode fluctuations which are strongly excited in a range of large electric-field shear are considered to be a Kelvin-Helmholtz instability. The drift-wave mode is stabilized with an increase in the radial electric field regardless of its sign, which also tends to be stabilized by the E×B drift velocity shear.
