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.

Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

Energy and particle transport rates in magnetically confined plasmas are often larger than neo-classical transport owing to binary collisions would allow. Anomalous transport, a major road block on the path to an economic fusion reactor, is a consequence of electric and magnetic fluctuations driven to supra thermal levels by various instability mechanisms. The linearly excited modes saturate by inducing a relaxation of the equilibrium profiles towards the marginally stable state, on the one hand, and via various non-linear interaction mechanisms, on the other hand. Specific instabilities, profile relaxation and non-linear interaction models are described and their successes and drawbacks are analysed in the light of observed characteristics of plasma confinement. A rough evaluation of the nuclear heating power required to balance the anomalous losses in the International Tokamak Experimental Reactor (ITER) is derived on the basis of the very qualitative mixing length estimate applied to electrostatic drift wave turbulence. Results from large-scale gyro-kinetic simulation codes are discussed.
