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.

Feinstein Institutes to research novel radiation countermeasure
The Feinstein Institutes for Medical Research, home of the research institutes of New York’s Northwell Health, announced it has received a five-year, $2.9 million grant from the National Institutes of Health to investigate the potential of human ghrelin, a naturally occurring hormone, as a medical countermeasure against radiation-induced gastrointestinal syndrome (GI-ARS).

The thermal-hydraulic system code ATHLET is one main component of the German code package AC2, developed at GRS for comprehensive analyses of nuclear power plants under design basis and beyond design basis accident conditions. In the frame of code validation, five of the eight experiments performed in the German integral test facility PKL within the OECD/NEA joint project PKL-3 have been selected for the evaluation of code capabilities. One main focus has been the simulation of station blackout (SBO) scenarios. Calculation results show that ATHLET can adequately reproduce the main experimental phenomena, including pressure and temperature evolutions, coolant distribution in the primary circuit, and restart of natural circulation in the loop with emergency feedwater injection. Another main contribution to code validation was the simulation of small break loss-of-coolant (SBLOCA) tests. These tests have been designed as counterpart tests to experiments previously performed at the Japanese LSTF facility, providing a sound indication of the scalability of code results.
