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.

Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

In this study, a three-dimensional transient metal hydride model is applied to two different depleted uranium (DU) bed designs. One bed is designed to contain 1.86 kg DU for a hydrogen isotope storage capacity of 70 g, and it is loaded with copper foam to enhance internal heat transfer. The other bed is designed to contain 5.26 kg DU for a hydrogen isotope storage capacity of 200 g, and it uses copper fins to enhance internal heat transfer. A numerical study is conducted to analyze the dehydriding characteristics of two different DU bed designs. A parallel computing methodology is used to effectively reduce the computational turnaround time involved for full-scale DU bed geometries. The detailed simulation results show the evolution of temperature and hydrogen-to-metal atomic ratio contours at different hydrogen desorption stages and reveal the different DU dehydriding behaviors of the two DU beds. In sum, the present work elucidates the effects of key bed design parameters and helps identify optimal DU bed design strategies to effectively charge and discharge hydrogen isotopes.
