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.

Zap Energy hits 37-million-degree electron temperatures in compact fusion device
Zap Energy announced April 23 that it has reached 1-3 keV plasma electron temperatures—roughly the equivalent of 11 to 37 million degrees Celsius—using its sheared-flow-stabilized Z-pinch approach to fusion. Reaching temperatures above that of the sun’s core (which is 10 million degrees Celsius temperature) is just one hurdle required before any fusion confinement concept can realistically pursue net gain and fusion energy.

Lecture | Fourth ITER International Summer School (IISS2010) | doi.org/10.13182/FST11-A11690
Articles are hosted by Taylor and Francis Online.
This lecture was given at the 4th ITER International Summer School in Austin, Texas, May 31-June 4, 2010. It reviews the recent experimental and modeling progress made to design real-time kinetic and magnetic profile control of advanced scenarios for steady-state tokamak operation. The lecture addresses four challenging issues that need to be resolved and that are open to future research activities: (a) how to operate a tokamak in a continuous manner, (b) how to control the core kinetic and magnetic profiles of tokamak plasmas, (c) how to control the fusion burn in plasmas with dominant self-generated bootstrap non-inductive current and fusion-born alpha heating, and (d) how to control simultaneously core and edge plasma parameters.
