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.

Digital control system installed at China’s Linglong One
Earlier this month, the first digital control system was put in place at Linglong One, a small modular reactor demonstration project being built at the Changjiang nuclear power plant in Hainan Province. This is the world’s first land-based commercial SMR and is controlled by China National Nuclear Power Co. Ltd., a subsidiary of the China National Nuclear Corporation (CNNC).

In this work, the full energy peak efficiency for a system of two NaI gamma detectors using spherical radioactive sources is evaluated by applying a new numerical algorithm method, since experimental calibration using volumetric sources is a dominant problem of practical gamma spectrometry. The new method is based on the efficiency transfer technique, where the effective solid angles, the effect of self-absorption of the source matrix, and absorption by the source container and the detector housing materials on detector efficiency are considered. The experimental calibration procedure was done using radioactive spherical sources containing aqueous 152Eu radionuclide, which produces photons with a wide range of energies from 121.78 up to 1408.03 keV. The comparison shows good agreement between the measured and calculated efficiencies for the detector using spherical sources.
