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.

TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

The Tritium Emissions Reduction Facility (TERF) is an automated process that continuously removes tritium from process gases before they are discharged to the atmosphere. Key control parameters include: temperature, pressure, flow, oxygen content, total combustibles, moisture concentrations and tritium concentrations. The procurement of an industrial, microprocessor-based Distributed Process Control System was justified for TERF due to the critical nature and complexity of the system. A detailed performance specification was prepared and submitted to industrial companies who had demonstrated past success in the field of process control and instrumentation. The contract was awarded to the Foxboro Company, of Foxboro, Ma., who developed the new Intelligent Automation (I/A) Distributed Process Control System. A primary goal of the design team was that the control system increase TERF reliability and availability by automatically controlling system operation and by assisting the operator in the diagnosis of problems, preventative maintenance, alarming, report generation, and long term storage of data. The comprehensive continuous monitoring of the TERF process provided by the Foxboro I/A Distributed System is expected to: (1) optimize the system operating parameters and control the process better than was previously possible, (2) provide more alerts and alarms to aid operators in diagnosing and responding to problems, and (3) record and organize process data more effectively than before.
