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.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

An imaging spectroscopy becomes one of the fundamental method of the radial profile study of the light impurities line emission of high temperature plasmas. The application of the spherical dispersion elements (as diffraction grids and a multilayer mirrors) makes it possible an image of the radial profile of the chosen spectral line intensity.
The line spectrum measurements of the light impurities emission in 50 - 200 nm wavelength range at different plasmas equipment (tokamak CASTOR and GOL-3) has been provided by Seya-Namioka spectrometer equipped by spherical diffraction grid and a two dimensional detection system. The especial arrangement of the optical trace has been used for high imaging resolution in plasma radial direction.
The novel diagnostic method can provide the way of impurity transport investigation [1]. It is well known, the transport effects lead to some deviations of the radial distribution of the line emission density from those calculated using pure coronal equilibrium. They can be deduced from chordal measurements of the radial profiles of the spectral line intensity and or intensity ratios of spectral lines of different ionisation stages both measured by chord-integrating spectrometer.
