ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

Vogtle-3 achieves full power output
The Vogtle expansion project’s Unit 3 reactor has attained 100 percent energy output—the first time it has reached its maximum expected output of approximately 1,100 MWe, Georgia Power announced yesterday.
Workshop 1 (below)

Description: The Fire Risk Investigation in 3D (FRI3D) software was initially developed as part of the research for enhanced fire analysis under Light Water Reactor Sustainability (LWRS) program. The goal of this software has two parts: (1) provide industry with a tool to simplify the process for developing and using detailed fire models; (2) provide a back-end for future enhanced fire analysis and possible extension to dynamic probabilistic risk analysis models. The FRI3D software was developed over the last two years to integrate 3D spatial modeling with existing fire probabilistic risk assessment (PRA) models and fire simulation codes.
Attendees will receive a certificate of attendance for these workshops.
Workshop #1 will be recorded and have access to the recorded presentations after the workshop.
Purpose of Workshop: Learn how to use FRI3D software to perform fire modeling and PRA. FRI3D encapsulates the fire and plant data into a unified database and simplifies the process with automated simulations using CFAST, THIEF, Heat Soak Methods. The workshop will serve as a guide to use FRI3D to perform Fire PRA and advanced fire modeling.
Presenter Bios: Ramprasad (Ram) Sampath is the founder and CEO of Centroid LAB an engineering software consultancy firm performing Advanced Visualization and Computational Dynamics and Simulations.
Steven Prescott, is a software analysis/integration engineer for the Risk Assessment and Management Services Department at Idaho National Laboratory. He specializes scientific and technical software design and development.

Description: To facilitate the deployment of advanced nuclear power reactors, it is time-critical to focus on the risk-informed analysis of advanced reactors prior to, or in parallel with, technology developments. In recent years, there have been major efforts in the PRA developments for advanced reactors and its use in risk-informed decision-making, such as the Licensing Modernization Project (LMP), development of Title 10 of the Code of Federal Regulations, Part 53 (10CFR53) and other regulatory guidance by the Nuclear Regulatory Commission (NRC), as well as issuance of the ASME/ANS Non-LWR Probabilistic Risk Assessment Standard (RA-S-1.4-2021); however, there are still significant research needs for methodology developments. One of the key methodological challenges is that a design-specific experiential database is often limited or not available for advanced reactors, while the applicability and relevancy of the experiential data from the existing fleet to advanced reactors may be questionable due to differences in design principles, physical conditions, and operation and maintenance procedures. This workshop discusses the challenges and highlights possible research paths to alleviate them. As an example of the recent research activities, the methodological advancements and benchmark studies in an International Atomic Energy Agency (IAEA) Coordinated Research Project, “Methodology for Assessing Pipe Failure Rates in Advanced Water Cooled Reactors (WCRs),” are demonstrated. Based on the outcomes and insights from this IAEA project and other recent research activities, recommendations regarding the risk-informed analysis of advanced reactors are provided.
Purpose of Workshop: Identify the needs and methodological challenges in risk-informed analysis for advanced nuclear power reactors. Discuss research directions and paths to address those needs and challenges to facilitate the deployment of advanced reactors. As a case study, demonstrate the ongoing IAEA coordinated research project and provide recommendations.
This workshop will be led by the Socio-Technical Risk Analysis (SoTeRiA) Research Laboratory in the Department of Nuclear, Plasma, and Radiological Engineering at the University of Illinois at Urbana-Champaign.
