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.

NWMO to select Canadian repository site this year
Canada’s Nuclear Waste Management Organization, a not-for-profit organization responsible for the long-term management of the country’s intermediate- and high-level radioactive waste, is set to select a site for a deep geologic repository by the end of the year.

A sodium-cooled fast reactor (SFR) self-actuated shutdown system (SASS) is a passive safety feature by which control rods are inserted by gravity force and the rods would be detached by a rise in coolant temperature under anticipated transient without scram (ATWS) conditions. Various out-of-pile tests have already been carried out to investigate the basic characteristics of SASS, and a demonstration test of the holding stability under reactor operation conditions has been performed, where a function test of the driving system to reconnect and pull out the control rod has been done in the experimental reactor JOYO. Element irradiation tests have also been conducted to confirm that there is no impact from irradiation. The effectiveness of SASS for the reference core design of the Japan SFR (JSFR) has been evaluated through all ATWS types. As a result, it is ensured that JSFR will have a reliable passive shutdown system.
