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.

Argonne’s METL gears up to test more sodium fast reactor components
Argonne National Laboratory has successfully swapped out an aging cold trap in the sodium test loop called METL (Mechanisms Engineering Test Loop), the Department of Energy announced April 23. The upgrade is the first of its kind in the United States in more than 30 years, according to the DOE, and will help test components and operations for the sodium-cooled fast reactors being developed now.

The solubility of iron and nickel from a nonstoichiometric nickel ferrite in a hydrogen-containing aqueous solution of 0.2 M boric acid was determined in a flow system between 330°C (626°F) and room temperature. The data are relevant to the dissolution and precipitation of corrosion products from the primary coolant system surfaces in pressurized water reactors during operation and cooldown. Solubility maxima of 4.2 ppm iron and 1.0 ppm nickel were obtained at 80°C (175°F). The results are shown to be consistent with published data for iron from magnetite in hydrochloric acid at the same pH between 330 and 120°C, but to be lower by a factor of 106 at room temperature. The low solubility in the low-temperature region suggests that a quasi-equilibrium can be established with a borated surface that passivates the ferrite substrate.
