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 main results of several years of research on neutron and gamma-ray physics in the Purdue Fast Breeder Blanket Facility (FBBF) are summarized. Presented are neutron capture rates in 238U, 232Th, gold, tungsten, and manganese, and fission rates in 235U and 239Pu. Neutron spectra are determined from proton recoil energies over the range from 2 keV to 2 MeV. The energy deposition of the gamma-ray field is measured with thermoluminescent detectors. Since the FBBF is a source-driven facility, all results are obtained on an absolute basis and are compared with corresponding calculations. Most of the results are presented as calculated/experimental trajectories except for the neutron spectra. The absolute and complete experimental results will be presented in separate papers. The comprehensive and coherent interpretation of deviations between calculated and experimental results is explored. Three major deviations are identified; they concern the “bulk” of the neutron population, the low-energy wing of the spectrum, and the space dependency of resonance absorption.
