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.

NC State celebrates 70 years of nuclear engineering education

The Department of Nuclear Engineering at North Carolina State University has spent the 2020–2021 academic year celebrating the 70th anniversary of its becoming the first U.S. university to establish a nuclear engineering curriculum. It started in 1950, when Clifford Beck, then of Oak Ridge, Tenn., obtained support from NC State’s dean of engineering, Harold Lampe, to build the nation’s first university nuclear reactor and, in conjunction, establish an educational curriculum dedicated to nuclear engineering.
The department, host to the 2021 ANS Virtual Student Conference, scheduled for April 8–10, now features 23 tenure/tenure-track faculty and three research faculty members. “What a journey for the first nuclear engineering curriculum in the nation,” said Kostadin Ivanov, professor and department head.

The hydrophobic catalysts were originally conceived in Canada for the deuterium enrichment and tritium separation by hydrogen-liquid water isotopic exchange in nuclear field. Unlike the conventional hydrophilic catalysts, which becomes inefficient to direct contact with liquid water, the hydrophobic catalysts kept a high catalytic activity and stability, even under the direct contact with liquid water or in presence of humid gas. Based on the long experience of the authors, in the preparation, testing and evaluation of the performances of hydrophobic catalysts, and based on the reviewed references, this paper presents up-to-date R&D activities on the preparation methods and applications of the hydrophobic catalysts, in tritium separation. The objectives of the paper are: (1) to provide a database for selection of the most appropriate catalyst and catalytic packing for above mentioned processes (2) to asses and to find a new procedure for preparation of a new improved hydrophobic catalyst. From reviewed references we consider that platinum remains the most active and efficient catalytic metal and the TEFLON is the best wetproofing agent. A new improved hydrophobic Pt-catalyst has been proposed and is now underway. The main steps and experimental conditions of preparation are largely discussed. A new wet-proofing agent and a new binding agents (titanium oxide, cerium oxide, zirconium oxide) with catalytic role are proposed and tested. The physico-structural parameters of new improved catalyst have been determined and are discussed in details. The new proposal is a promising idea to improve the performances of conventional hydrophobic Pt-catalysts.
