ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

Nicholas Tsoulfanidis—ANS member since 1969
As an undergraduate I studied physics at the University of Athens. I entered the university in 1955 after successfully passing a national exam (came up fourth in a field of about 700 candidates). Upon graduation and finishing my mandatory two-year military service, the plan was to teach physics either in a public high school or as a tutor for a private for-profit institution, preparing high school students for the national exam.

Erbium oxide (Er2O3) coating layer is one of the suitable coatings to realize an advanced breeding blanket system because it has high electrical resistivity and hydrogen permeation suppression effect. In order to enhance these properties of Er2O3 coating, it is necessary to form a thick coating layer with high crystallinity. The formation of a double stacked coating layer on an austenitic stainless steel 316 substrate using an intermediate layer (buffer layer) was investigated for the thicker and high crystallinity of Er2O3 coating formation. Yttrium oxide (Y2O3) and cerium oxide (CeO2) were selected as buffer layer between the Er2O3 layer and austenitic stainless steel 316 substrate due to their similar lattice constant to that of Er2O3 crystal. The texture and grain growth direction of Er2O3 was controlled by the Y2O3 and CeO2 buffer layer. However, the suppression effect of hydrogen permeation by the double stacked coating was smaller than that of the single layer coating due to the thin Er2O3 formation.
