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 which extend to the area of light water reactor long-term operation and proposed modification for light water reactor sustainability LWRS Status Highlights Main Goal: enable plant efficiency improvements through a strategy for long-term modernization Research Areas:
Digital Infrastructure:
Latest Report: Digital Infrastructure Industry Engagement Recap: This research provides a generic technology strategy and is presented from a technology platform point of view. This platform is ultimately the union of an in-tegrated digital infrastructure (DI) and data architecture and analytics (DA&A) appli-cations selected to operate on it. Specific technologies and software applications are researched, developed, implemented, and then integrated to optimize both the performance of the technology and the capabilities of users who leverage it.
Integrated Operation for Nuclear (ION):
Latest Report: Integrated Operations for Nu-clear Business Operation Model Analysis and Industry Validation Recap: This report presents five work reduc-tion opportunities (condition-based mainte-nance, digital I&C and digital control room, automated planning and scheduling, ad-vanced training technology, and remote assis-tance and automated troubleshooting) that can be implement in the current nuclear power plant fleet.

Main Goal: develop safety analysis methods and tools to optimize the safety, reliabi-lity, and economics of nuclear power plants Research Areas:
Risk-Informed Asset management:
Bridging Equipment Reliability Data and Robust Decisions in a Plant Operation Context-This report shows the latest improvements on a new risk analytics toolset.
This toolset consists of data analytics tools coupled with reliability methods designed to manage plant assets and performances in a predictive maintenance context.
An Integrated Framework for Risk Assess-ment of High Safety-significant Safety-related Digital Instrumentation and Control Systems in Nuclear Power Plants: Methodol-ogy and Demonstration-This report provides a best-estimate, risk-informed capability to quantitatively and accurately estimate the safe-ty margin obtained from plant modernization, especially for the high safety-significant safety-related (HSSSR) DI&C systems and supports and supplements existing advanced risk-informed DI&C design guides by providing quantitative risk information and evidence.
Risk Informed System Analysis (RISA) Pathway Page 2 Materials Research Pathway Main Goal: understand and predict long-term behavior of materials in nuclear power plants Research Areas:
Metals-No updates for this month Concrete-Stress Corrosion Cracking (SCC) on Ni-base Alloys in PWR Pri-mary Water Containing KOH vs. LiOH In this report presents a SCC evalua-tions on selected materials in both LiOH and KOH-containing PWR primary wa-ter chemistries. This report documents the research progress accomplished on this topic, focusing on the SCC growth behavior of Alloy X-750, Alloy 718 and Alloy 82H.
Cables: Inverse Temperature Effects in Nuclear Power Plant Electrical Ca-ble Insulation-In this report, two electrical cable insulation materials most commonly used in containment in nuclear power plants considering second li-cense renewal, Brand-Rex Ultrol cross-linked polyethylene (XLPE) and Samuel Moore Dekoron ethylene-propylene diene monomer (EPDM), were investigated to better understand inverse temperature effects in these materials.

Physical Security Pathway Main Goal: develop technologies and technical bases to optimize physical security Research Areas Advanced Security Technologies Safety Integration of Physical Security Simula-tion Software Application in a Dynamic Risk Framework-This document presents a dynamic modeling and simulation frame-work to enable physical security optimiza-tion at commercial nuclear power plants.
The framework is based on Event Modeling Risk Assessment using Linked Diagrams (EMRALD), the dynamic modeling tool, and is demonstrated for applications that can result in physical security optimization.
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 Reports:
Multi-Facility Coordinated Thermal Power Dispatch Research Plan: This report presents a multi-facility coordinated research plan for analyzing integrated electric and thermal power dispatch from com-mercial light water reactors (LWRs) to tertiary industrial loads.
Production of Fischer-Tropsch Synfuels at Nuclear Plants: This report presents a case study analysis that evaluated nuclear-powered synthetic fuel production in the midwestern Unit-ed States (U.S.). A Fischer-Tropsch (FT) fuel synthesis plant design was used as the basis for the analysis. The FT plant design was configured to produce a product slate consisting of diesel fuel, jet fuel, and motor gasoline blend stocks from carbon dioxide (CO2) and hydrogen (H2) feedstocks.
