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.

“Summer time” again? Santee Cooper thinks so
South Carolina public utility Santee Cooper and its partner South Carolina Electric & Gas (SCE&G) called a halt to the Summer-2 and -3 AP1000 construction project in July 2017, citing costly delays and the bankruptcy of Westinghouse. The well-chronicled legal fallout included indictments and settlements, and ultimately left Santee Cooper with the ownership of nonnuclear assets at the construction site in Jenkinsville, S.C.

The purpose of this paper is to provide an overview of the development of the Diversity and Defense-in-Depth (D3) strategy for the TerraPower Traveling Wave Reactor, TWR-300 Advanced Nuclear Power Plant. Previously, a D3 analysis was performed for the TWR-P Digital Control System (DCS) being designed by TerraPower for the TWR-P (prototype) reactor design. This paper provides an update on the D3 report specifically applicable to the TWR-300, which will be the first TWR Plant deployed. The Instrumentation and Control (I&C) design and configuration were based on standard digital control products. The control systems making up the DCS were selected because of their applicability to the functions required by TerraPower and the United States Nuclear Regulatory Commission (USNRC). The recommended installation of a digital-based Plant Protection System (PPS) and other systems throughout the TWR-300 enhances safety in many areas when compared to the previous generation of analog-based instrumentation systems.
