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.

Values of the crack tip opening stretch (COS), the stress intensity factor, Keff, and the energy integral J were determined for 22 Ni Mo Cr 3 7 steel at room temperature. A material-dependent linear relationship between COS and J resulted. The critical values of COS and J determined for the onset of stable crack growth using the electrical potential method and the interrupted loading procedure were independent of specimen type and crack length for thicknesses smaller than 30 mm. A dependence on crack length, although accompanied by large scatter, was indicated for 75-mm-thick specimens with an instability type of fracture behavior.
