Light Water Reactor Sustainability (LWRS) is a Department of Energy (DOE) program conducting research to develop technologies and other solutions to improve the economics and reliability, sustain the safety, and extend the operation of our nation's fleet of nuclear power plants (NPP). The NRC and the DOE has a Memorandum of Understanding (MOU) on Nuclear Innovation that allow the entities to share expertise 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 Latest Report :
Digitalization Guiding Principles and Method for Nuclear Industry Work Processes -
This report documents activities from the Work Digitalization Initiative, which was conceived as a means for nuclear organizations to help define and standardize the industrys approach to digitalizing work. It also presents a digitalization use case with industry partners NextAxiom Technology and Xcel Energy. The project objective was to transform the current condition report work process from paper to digital, incorporating digitalized principles.

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 Latest Report:
Machine Learning for Processing Ultrasonic Data from Long-Term Monitoring of Concrete with Alkali-Silica Reaction (ASR)- In this report, four machine learning (ML) models were established and comparatively evaluated to establish a relationship between concrete expansion due to ASR and ultrasonic signals. Two concrete specimens intentionally designed to exhibit ASR development were cast and conditioned in a curing chamber to accelerate ASR.
Over a span of more than 500 days, ultrasonic signals and expansion data were collected continuously on these specimens.
Survey of Aging and Monitoring Concerns for Cables and Splices Due to Cable Repair and Replacement-This report surveys aging and monitoring concerns for electrical cable splices in NPP in long-term operation. As portions of existing electrical cable runs in NPP are replaced over time due to localized events, the total number of splices in NPP are expected to increase.
NRCs Licensee Event Reports database was used to identify documented issues of electrical cable and splice failure. The trend in resultant data over time was considered to see if failures were increasing as NPPs age.
Main Goal: develop safety analysis methods and tools to optimize the safety, reliability, and economics of nuclear power plants Latest Report:
Pressurized-Water Reactor Core Design Demonstration with Genetic Algorithm Based Multi-Objective Plant Fuel Reload Optimization Platform-This report summarizes development and demonstration activities of the Plant Reload Optimization Platform built in the Risk Analysis and Virtual ENviroment, specifically: improvement of multi-objective non-dominated sorting genetic algorithm II to handle large size of objectives and constraints; demonstration of pressurized-water reactor core design with the non-dominated sorting genetic algorithm II multi-objective optimization platform, and single-objective, optimized core design, including system analysis and fuel performance feedback.

Risk Analysis of a Hydrogen Generation Facility near a Nuclear Power Plant-The purpose of this study is to investigate the risk of a hydrogen production facility in close proximity to an NPP. A 100 MW, 500 MW, and 1,000 MW facilities were evaluated. This analysis specifically evaluates the risk components of different hydrogen production facility designs, including the likelihood of a leak within the system and the associated consequence to critical NPP targets.
