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.

Manganese-stabilized steels have been proposed as candidate structural materials for fusion reactors, because they have been perceived as “low-activation” materials. Depending on the neutron spectra and the neutron fluence, the decay heat in Mn-stabilized steels is about 3–7 times larger than that in the Ni-stabilized steels. This large amount of decay heat could have serious impact in the case of the loss of coolant accident (LOCA). A two-dimensional LOCA model has been used to examine the LOCA temperature response of the manganese steel when utilized in an earlier U.S. design of ITER. The results show that the Mn-steel has approached its melting temperature by less than 100°C after about 7 hours from the onset of LOCA. On the other hand, the results for the nickel stabilized steel alloy 316SS show that the maximum temperature reached is 532°C in about the same time.
