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.

Constellation seeks rezone for property adjacent to Illinois plant
While no development details have been released, Constellation is asking to rezone 658.8 acres of land it owns around the Byron nuclear plant in Illinois for possible long-term use.

The Korea 150 MWe Prototype GEN-IV Sodium cooled Fast Reactor (PGSFR) project has reached the middle of its preliminary safety analysis report (PSAR) design phase. Core design studies are being conducted by KAERI. Some design features for the core have been made to comply with the PGSFR objectives.
The multi-discipline considered reactor core shutdown system was carried out. There are many considerations to consider when designing a reactor core shutdown system, which are the reactor hydraulics, safety analysis, structural and neutronics design viewpoints. This paper describes the control rod for the PGSFR core at the end of the PSAR phase and studies performed to optimize the performances. Focus is placed on innovations and specificities in the design compared with the PGSFR.
To determine whether the previous reactor shutdown system, it satisfies each design requirement through analysis or experimental methods. To provide diversity, these core shutdown systems are considered two types of control rod drive mechanism (CRDM), which are the primary and secondary control rod assemblies (CRA).
