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.

Retrieval of nuclear waste canisters from a borehole
Borehole disposal of spent nuclear fuel (SNF) and high-level waste (HLW) uses off-the-shelf directional drilling technology developed and commercialized by the oil and gas sectors. It is a technology that has been gaining traction in recent years in the nuclear industry. Disposal can be done in one or more boreholes (including an array) drilled into suitable sedimentary, igneous, or metamorphic host rocks. Waste is encapsulated in specialized corrosion-resistant canisters, which are placed end to end in disposal sections of relatively small-diameter boreholes that have been cased and fluid-filled. After emplacement, the vertical access hole is plugged and backfilled as an engineered barrier.

The Japan Atomic Energy Research Institute (JAERI) has developed a full scale Fuel Cleanup System (JFCU) that processes a simulated plasma exhaust at the Tritium Systems Test Assembly (TSTA) in the Los Alamos National Laboratory (LANL). The JFCU was designed by the Tritium Process Laboratory (TPL) of the JAERI based on the component studies performed under previous TSTA-TPL collaboration and the pilot scale experiment using grams of tritium at the TPL. The JFCU accepts a simulated fusion reactor exhaust, a mixture of hydrogen isotopes with an impurity level of up to 15% at a throughput of 4.2x10−3 mol/s continuously and produces pure hydrogen isotopes while exhausting tritium-free waste gas. Some newly developed components, such as the Ceramic Electrolysis Cell and the large Zirconium-Cobalt bed, required special attention during fabrication and assembly. The apparatus was fabricated by Mitsubishi Heavy Industries (MHI) and installed at the TSTA in early 1990. Interfacing with the existing TSTA facility also required careful interaction between TSTA and JAERI.
