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.

ARPA-E announces $40 million to develop transmutation technologies for UNF
The Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E) announced $40 million in funding to develop cutting-edge technologies to enable the transmutation of used nuclear fuel into less-radioactive substances. According to ARPA-E, the new initiative addresses one of the agency’s core goals as outlined by Congress: to provide transformative solutions to improve the management, cleanup, and disposal of radioactive waste and spent nuclear fuel.

Composite coatings containing beryllium are prepared by plasma-enhanced chemical vapor deposition at a substrate temperature as low as 250°C in a radio-frequency-induced cylindrical plasma reactor. Diethylberyllium is used as the precursor together with hydrogen as a coreactant gas. These coatings are characterized by Auger electron spectroscopy (AES), X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy, atomic force microscopy, electrical resistivity, and thermogravimetric analysis. AES indicates that the composition of the coatings reaches a steady level at a depth of 300 Å from the surface and maintains a constant composition throughout the thickness of the coatings. The characterization studies establish the dominant phase to be Be2C. The coatings are also resistant to oxidation and hydrolysis in dry/moist air unlike bulk Be2C. It is found that the coatings deposited close to the diethylberyllium inlet contain amorphous beryllium that is homogeneously dispersed in a Be2C matrix. Films of ~5-m thickness with an acceptable permeability to H2 are prepared. These coatings meet some of the major requirements of the ablator material for inertial confinement fusion target capsules.
