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.

Tritium permeation, particularly plasma driven permeation (PDP) through plasma facing materials has been identified as a critical safety issue for future fusion power devices. While PDP through metals has been reported earlier, this work presents the first measurements of permeation rates through SiC/SiC composite samples exposed to a modified RF-discharge plasma device. The response of the SiC/SiC composite samples to impinging plasma radiation was also investigated using SEM. In contrast to metals, SiC/SiC composite showed no evidence of PDP of deuterium. The SEMs revealed attack only of directly exposed fibers and fiber-matrix interfaces. In lieu of these measurements, SiC/SiC composites offer promising characteristics as plasma facing materials for future fusion devices.
