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.

A shattered pellet injector (SPI) based on in situ technology was developed in the HL-2A tokamak. In this paper, the basic principle of pellet formation is introduced, the mechanism of a SPI is described in detail, and test results are presented. Bench test experimental results show that reliable formation and acceleration of a large nitrogen pellet (diameter of ∼3.5 × 4 mm) were obtained. A double-impact tube was developed and tested for effective and reliable shattering of the pellet.
