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.

Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

Disruption mitigation in tokamaks by impurity injection aims to reduce the heat load and mechanical forces and to collisionally suppress runaway electrons. Rapid injection of sufficient mass, high penetrability, and large assimilation fraction in the core plasma together with rapid impurity redistribution over the whole plasma are required. FAR-TECH Inc. proposed the innovative idea of using hypervelocity ([greater-than or equivalent to]4 km/s), high-density ([greater-than or equivalent to]1017 cm−3), high-ram-pressure C60 nanoparticle plasma jets to deliver the impurity mass in [approximately]1 ms. For this purpose a large C60 gas mass of explosively sublimated powder, generated by a solid-state, pulsed-power-driven source injector cartridge containing TiH2 grains and C60 powder, is ionized and accelerated in a plasma accelerator. We report here the characterization of the TiH2/C60 injector cartridge using a 5-kJ capacitive driver, which produced up to [approximately]210 mg of C60 gas in <0.5 ms. The TiH2/C60 cartridge is the key component of the 100-kJ coaxial plasma gun ([approximately]35-cm length) prototype developed for a proof-of-principle experiment on a tokamak. Three-dimensional simulations show that a heavy C60 plasmoid penetrates deeply, as a compact structure, through a transverse magnetic barrier.
