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.

Ariz. governor vetoes “fast track” bill for nuclear
Gov. Katie Hobbs put the brakes on legislation that would have eliminated some of Arizona’s regulations and oversight of small modular reactors, technology that is largely under consideration by data centers and heavy industrial power users.

A high-speed photographic investigation established the general nature of the explosive interaction between hot molten metal jets and subcooled (75°F) distilled water. The photographic sequences yielded basic information concerning the relationship between extent of material fragmentation and the intensity of explosive action. Prior theories for the explosive causative mechanism were show to be inadequate to explain the observed explosive action. A thermally controlled initiating mechanism is hypothesized and the experimental evidence supports the hypothesis. Dimensional analysis yields a parameter dominated by the thermal characteristics of the jet system.
