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.

Used nuclear fuel transportation casks are subjected to a permanent heat load that must be released in the air by passive dissipation as natural convection and infrared radiation. Because of the large size of the cask, natural convection operates in nonisothermal conditions at very high Rayleigh numbers where few experimental works exist and where computational fluid dynamics codes are often not representative. Thermal tests are then needed to estimate and check thermal designs. This work is a starting point of a research and development program that aims to improve the knowledge of natural convective heat transfer around casks, to explain the effect of a design parameter such as fins, and finally to propose and check improved solutions. In this work, we present the qualification of a mock-up that has been set up to measure the local heat convective coefficient of a fin-equipped cask in transport conditions. The geometry concerns short axial fins that are widely used on transportation/storage casks. The first results show a large variation of the heat convective coefficient along the cask from a constant low level at the bottom and then a linearly increasing level leading to a maximum value close to the top that is strongly temperature dependent.
