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.

The dynamic plunging behavior of a subcooled water jet into a pool of molten lead-bismuth alloy, visualized and measured using high-frame-rate neutron radiography, is described. It is shown that the interactions between water and heavy melt in this geometry differ in several aspects from those in melt injection into water investigated extensively in relation to fuel-coolant interactions. The maximum depth of jet penetration is limited by the buoyancy on and the onset of bulk boiling in the water which has collected in a "cavity." The bulk boiling starts as the subcooled water supply to the cavity becomes limited due to pinching instabilities in the upper region of the cavity. This leads to a transition to the final steady state.
