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 :
Assessment of Cloud-based Applications Enabling a Scalable Risk-informed Predictive Maintenance Strategy - This report examines the capabilities, feasibility, and regulatory concerns of cloud computing in relation to meeting nuclear industry needs in collaboration with Oak Ridge National Lab and Blue Wave AI Labs. The technical viability of cloud computing was analyzed using data from a boiling-water reactors safety relief valve.
November 2023 Plant Modernization Pathway Program Mission Proposed high-level architecture of the hybrid cloud
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:
Comprehensive Characterization of Repair Welding Performed on Irradiated Nickel (Ni) Alloy 182-This report describes the research activities on post-weld evaluation and characterization of the quality and properties of welds made on the first phase of repair welding campaign on irradiated Ni alloy 182.
Irradiated Ni alloy 182 with doped boron ranging from 5 weight parts per million (wppm) to 15 wppm, were laser welded in the hot cell. The weld samples were cross-sectioned and characterized.
Spread Spectrum Time Domain Reflectometry (SSTDR) and Frequency Domain Reflectometry (FDR) for Detection of Cable Anomalies Using Machine Learning - This research discusses application of machine learning (ML) to reflectometry cable test methods. The goal was to assess feasibility to distinguish undamaged cable reflectometry responses from damaged or anomalous cable reflectometry responses. The assessment considered 3 instruments, multiple frequency bandwidths from each instrument, multiple cable anomalies and test conditions, and both supervised and unsupervised ML approaches.
Main Goal: develop safety analysis methods and tools to optimize the safety, reliability, and economics of nuclear power plants Latest Report:
Development of Analysis Methods that Integrate Numeric and Textural Equipment Reliability (ER) Data-This report presents in detail the integration and reasoning from numeric and textual ER data elements. The research includes the development of the library of model-based system engineering (MBSE) models that focus on common NPP systems and assets. It also includes the development of computational methods designed to process and analyze numeric and textual ER data elements simultaneously. An application of the computational methods on the circulating water system of an existing NPP is also presented. The final considerations provide additional insights on further potential applications of these methods to support additional NPP decisions.

Comparison of Energy Storage and Arbitrage Options for Nuclear Power-The purpose of this report is to compare and rank energy storage technologies that can store energy from an LWR for a wide spectrum of storage durations. For the purposes of this report a 500 MWe-AC of discharge capacity was chosen as the capacity upon which all of the energy storage options are compared. The options herein evaluated include: Utility Scale Lithium-ion Batteries, Power to Hydrogen to Power, and Thermal Energy Storage.
