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 November 2024 Material Research Pathway Program Mission Opening of grain boundaries with increasing neutron dose for a sample.
Main Goal: understand and predict long-term behavior of materials in nuclear power plants Latest Reports: Assessment of Neutron-Induced Crack Volume on Aggregates of Varied Mineralogy and Estimation of Irradiation Damage Depth in the Concrete Biological Shield -
This report provides a probabilistic analysis of the damage depth in the biological shield, considering average mineralogical compositions of sedimentary rocks as aggregates. It was found that the penetration depth is highly correlated with the aggregate volume fraction. The second part of the report describes a methodology to characterize volume fractions of neutron-induced cracks for aggregates of varied mineralogy, including some sedimentary rocks (i.e., sandstones), a tuff, and a limestone. Micro-XCT scans were analyzed using Dragonfly for crack volume segmentation.
Main Goal: develop safety analysis methods and tools to optimize the safety, reliability, and economics of nuclear power plants Latest Report : Huma Unimodel for Nuclear Technology to Enhance Reliability (HUNTER 3.0) User Guide - This report provides a user guide to aid human reliability analysts and researchers in simulating human performance in Rancor-HUNTER. The report includes brief histories of HUNTER and Rancor and a thorough discussion of the integrated Rancor-HUNTER software. An example of a Rancor startup scenario is provided to demonstrate virtual human-in-the-loop data generation with Rancor-HUNTER.

Hazards and Probabilistic Risk Assessments of a Light-Water Reactor Coupled with Industrial Facilities-This report provides a roadmap and toolkit for site-specific risk assessments across a broad range of industrial customers co-located with NPPs. The report expands the hazards assessments to include other industrial facilities: an oil refinery, a methanol plant, a synthetic fuel (synfuel) plant, the production of synthetic gas (syngas) as part of the methanol and synfuel plants, and wood pulp and paper mills. All these facilities are specified through industrial process and requirements research performed by national laboratories, universities, and interaction with industry. Many of the processes used in this report are pre-conceptual designs to use for decarbonization of the current technology facilities.

Main Goal: enable plant efficiency improvements through a strategy for long-term modernization Physical Security Pathway Main Goal: develop technologies and technical bases to optimize physical security Latest Report: No report for this issue Plant Modernization Pathway Latest Report: Integrated Operations for Nuclear: Work Reduction Opportunity (WRO) Demonstration-This demonstration report was developed to provide illustrative, specific, and actionable direction for intertwined people, technology, process, and governance (PTPG) changes associated with digital modernization efforts. The coordinated changes in these areas are intended to maximize safe plant operational and economic performance. This includes enabling WROs associated with detailed configuration, implementation, and use of digital systems and how they are supported over their lifecycle. Illustrating this direction through a minimum set of advanced technology examples establishes a model PTPG frame-work that can be leveraged across the spectrum of nuclear plant digital modernization efforts going forward.
