October 2022 LWRS Status Highlights Program Mission 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.
Plant Modernization Pathway 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- Forward-backward process to ensure reproducibility and interpretability plainable and trustable artificial intelli- of AI/ML technologies 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.
Page 2 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.
Risk Informed System Analysis (RISA) Pathway 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. Schematic diagram of ATF loaded PWR with extended burnup safety analysis 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.
Page 3 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 .
Flow for creating a base case comparison results 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.
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.
