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 technologies and chemical solutions for decontamination of high-power reactors are limited for use in small-scale power generation due to fundamental differences in operating conditions, fuel composition, fuel-element cladding structure, coolant water chemistry, and structural materials. The small space of the primary circuit and specific design and operational features have made it necessary to optimize the decontamination technologies for different stages of the naval rector plant (NRP) life cycle. Based on many years’ experience in maintenance, repair, and operation of NRPs, the principles for optimization of the process approaches are defined to reduce radioactive contamination of NRP equipment. In each particular case the decontamination technology is selected with due consideration for the NRP’s design, actual radioactive contamination, and the requirements for the cleanliness of the primary system after decontamination. This makes it possible to optimize the number of treatment cycles/stages and reagent consumption and to minimize the probability of recurrent deposit formation and the liquid radwaste amount.
