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.

The design and implementation of a simulated void-reactivity feedback in an experimental thermal-hydraulic loop meant for boiling water reactor (BWR)-dynamics studies is described. The void fraction in the loop is measured in real time and used as an input to a simulation that calculates the effect of void-reactivity on the reactor power. The resulting signals are used to control the power supplies of the loop. Advantages of this hybrid system in the study of BWR dynamics is that the complicated transfer functions related to two-phase flow are realized physically, while the relatively simple transfer functions related to the neutronics are simulated.
