The Light Water Reactor Sustainability (LWRS) is a Department of Energy (DOE) pro-gram conducting research to develop technologies and other solutions to improve the economics and reliability, sustain the safety, and extend the operation of our na-tion's fleet of nuclear power plants. The NRC and the DOE has a Memorandum of Understanding (MOU) on Nuclear Innovation that allow the entities to share exper-tise and knowledge on advanced nuclear reactor technologies and nuclear energy innovation.
LWRS Status Highlights Main Goal: enable plant efficiency improvements through a strategy for long-term modernization Research Areas:
Data Architecture:
Latest Report: Technical Basis for Advanced Artificial Intelligence and Machine Learning Adoption in Nu-clear Power Plants Recap: This report presents the technical basis for developing ex-plainable and trustable artificial intelli-gence (AI) and machine learning (ML) technologies. The technical basis will lay the foundation for addressing the technical and regulatory adoption challenges of AI/ML technologies across plant assets and the nuclear industry at scale and to achieve seamless cost-effective automation without compromising plant safety and reliability. Report here:
Integrated Operation for Nuclear (ION):
Latest Report: Using Information Automation and Human Technology Integration to Implement Integrated Operations for Nuclear Recap: This report develop and demonstrate an approach to the design and imple-mentation of advanced, automated systems intended to increase operational effi-ciencies at nuclear power plants. Report here.
October 2022 Plant Modernization Pathway Forward-backward process to ensure reproducibility and interpretability of AI/ML technologies Program Mission
Main Goal: develop safety analysis methods and tools to optimize the safety, reliabi-lity, and economics of nuclear power plants Research Areas:
Enhanced Resilient Systems:
Safety Analysis for Accident-Tolerant Fuels (ATF) with Increased Enrichment and Extended Burnup-This report pre-sents a safety analyses of ATFs with in-creased enrichment and extended burnup to provide scientific knowledge of the ATF fuel performance, failure mechanisms, and results from fuel failure source terms during a severe accident. Report here.
Risk-Informed Asset management:
Risk-Informed Initiating Events Accident Response-This report documents the economic benefits potentially available from the application of concepts associated with a modernized regulatory framework developed for advanced reactors to the ex-isting light water reactors. Timing factors were utilized to demonstrate the complexity of the existing risk assessments and described how these complexities affect regula-tory compliance activities at the plants. Report here.
Risk Informed System Analysis (RISA) Pathway Page 2 Schematic diagram of ATF loaded PWR with extended burnup safety analysis Materials Research Pathway Main Goal: understand and predict long-term behavior of materials in nuclear power plants Research Areas:
Metals-Microstructural Characterization of Second High Fluence Baffle-Former Bolt Retrieved from Westinghouse Two-loop Downflow Type PWR-This report present a microstructural characterizations of the second high flu-ence baffle-former bolt. Analytical electron microscopy and atom probe tomog-raphy characterization were performed. Report here.
Concrete-No updates for this month Cables: Inhomogeneous Aging of Nuclear Power Plant Electrical Cable In-sulation-This report documented the results of nuclear cables insulation sam-ples subjected to thermal aging at temperatures like those used in historic envi-ronmental qualification. The aged materials were characterized for effects of aging using the conventional tensile elongation at break for all samples. Report here.
Physical Security Pathway Main Goal: develop technologies and technical bases to optimize physical security Research Areas Advanced Security Technologies Safety Guidance Document for Using Dynamic Force-on-Force (FOF) Tools-This document provides a guidance for using the dynamic computational framework for optimizing physical security at nu-clear power plants. The instructions in this docu-ment cover the FOF tools that are used by a ma-jority of U.S. commercial plants for their physical security modeling and assessment. Report here.
Risk-Informed Physical Security Risk-Informed Adversary Timeline Tool-This report has a focus on reducing conservatisms in adversary timelines which potentially lead to over protection of a potential attack path resulting in inefficiencies in areas of a plants security posture.
Report here.
Page 3 Flexible Plant Operation and Generation Pathway Main Goal: enable diversification and increase revenue of light water reactors to pro-duce non-electrical products Latest Report: Plan for Scaling Up Hydrogen Production with Nuclear Power Plants Recap: This report outlines the opportunity for Nuclear Power Plants to participate in the commercial nuclear hydrogen project intended to create a regional clean hydro-gen hubs. Report here.
Updates: Based on the latest meeting within the industry and the agency INL Publication on 100 MW nominal design report and generic 10 CFR 50.59 eval-uation will be finalized by November.
