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.

Localization of loose parts is a crucial technique of a loose parts monitoring system for nuclear power plants. Accurate localization is beneficial for fault diagnosis and the continuous tracking of loose parts. Combined with time-frequency signal-processing methods, this paper presents a loose parts localization delay calculation method based on the continuous wavelet transform (CWT) and Hilbert envelope. First, it is identified that the signal is processed by CWT; second, the arrival time of the signal is determined by the Hilbert envelope method; and third, the grid localization method is applied to realize localization. This method, which uses the main frequency band of the impact signal as the Hilbert envelope localization signal, can minimize the effect of changes in the group velocity on time delay, and the Hilbert transform can obtain more accurate time delays. The experimental results show that this loose parts localization delay calculation based on the CWT and Hilbert envelope method has strong anti-interference capacity and high locating precision.
