ADVANCING THE STATE OF THE ART TO ACCELERATE ADVANCED REACTOR CONCEPTS AND HELP MAINTAIN AND EXPAND THE EXISTING FLEET OF LIGHT-WATER REACTORS
Innovation advances science. Historically, innovation resulted almost exclusively from fundamental theories combined with observation and experimentation over time. With advancements in engineering, computing power and visualization capabilities, new modeling and simulation tools are enabling scientists from all disciplines to gain insights into physical systems in ways not possible with traditional approaches alone.
Consequently, NE has engaged researchers and scientists in two complementary advanced modeling and simulation efforts to develop new tools to analyze and optimize the performance and reliability of existing and advanced nuclear power plants: the Energy Innovation Hub for Modeling & Simulation (Hub); and the Nuclear Energy Advanced Modeling & Simulation (NEAMS) program. Computational tools developed in these programs are allowing researchers to gain insights into current problems and new concepts in ways never before practical, and at levels of detail dictated by the governing phenomena, all the way from important changes in the materials of a nuclear fuel pellet to the full-scale operation of a complete nuclear power plant.
The Hub's objective is to develop and apply M&S tools focused on Light Water Reactor (LWR) technologies for an improved understanding of important operational and safety issues in existing reactors. The goal of these efforts is to enable industry to address reactor performance issues, implement innovative measures to help reduce costs, take advantage of accident tolerant fuels, allow up-rates, and implement load-following strategies, all of which are important to maintaining and expanding the existing LWR fleet. Please see Hub publications for technical information.
The objective of NEAMS is to develop and deploy predictive computer methods for the analysis and design of advanced reactor and fuel cycle systems focused on non-LWR technologies. Two key goals are to enable industry to accelerate advanced reactor concept development, and to support NRC confirmatory analysis for advanced reactors and fuels. Achieving these goals is necessary to sustain the advanced reactor pipeline, enable license application, and fully realize the economic and technological advantages of advanced concepts. Indeed, advanced modeling and simulation capabilities are crucial to advanced reactor commercialization and market penetration.
The purpose of the Nuclear Energy Advanced Modeling and Simulation (NEAMS) Software Verification and Validation (V&V) Plan is to define what...Learn More
