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.

Material damage through displacements per atom (DPA) and helium gas production, as well as the tritium breeding and energy absorption in an IFE (Inertial Fusion Energy) reactor chamber have been investigated with variable coolant zone thickness using different liquids. Examples are given for HYLIFE-II (an IFE reactor design) energy conversion chambers using Flibe (Li2BeF4), natural lithium and Li17Pb83 cutectic as both coolant and wall protection. To achieve a useful energy density for energy conversion purposes with sufficient tritium breeding (TBR= 1.1), material protection (DPA < 100 and He < 500 appm in 30 years of operation) and shallow burial criteria, coolant zone thickness values are found to be 56 cm for Flibe, 160 cm for natural lithium and 170 cm for Li17Pb83 with SS-304 as structural material.
Material damage investigations are extended to structural materials made of SiC and graphite for the same blanket. DPA values and He production rates in graphite turn out to be comparable to those in SS-304. However, they are higher in SiC, as compared to SS-304 and graphite.
