The mission of the Light Water Reactor Sustainability Program (LWRS) is to develop the scientific basis, science-based methodologies, and tools for the safe economical long-term operation of the nations high-performing fleet of commercial nuclear energy facilities LWRS Status Highlights Plant Modernization Main Goal: enable plant efficiency improvements through a strategy for long-term modernization Research Areas:
Digital Infrastructure:
Currently: developing scope and implementation plan for deploying the Digital Infrastructure.
Next Phase: Demonstrate a full-scale business case analysis for implementing a comprehensive digital infra-structure upgrade.
Data Architecture:
Currently: developing a data portal for inspec-tions, piloting the portal on PI&R inspection, and equipping the data portal with automated means of data analysis to verify compliance Next Phase: Connection of data portal to collabo-rating nuclear power utilities and expansion of its scope and capabilities Human & Technology Integration:
Currently: demonstrating the early guidance developed to support developing a new vision and adoption of advanced automation and technology; collaborating with Constellations Limerick digital safety-related upgrades in performing function and task analysis; collaborating with Southern to inform the development of Farleys new concept of operation and vision Next Phase: full-scale pilot Integrated Operation for Nuclear:
Currently: evaluating the innovation necessary to deliver a technology-centric and highly automated busi-ness model; benchmarking five areas with industry (Digital I&C Updates, Condition Based Maintenance, Remote Plant Support, and Automated Troubleshooting, Digital Training Transformation, and Automated Planning & Scheduling) More details here.
Next Phase: broad scope analysis of additional work reduction opportunities, demonstrating the effective-ness of ION guided plant modernization August 2022 Data Architecture for an Automated Plant
Main Goal: develop safety analysis methods and tools to optimize the safety, reliabil-ity, and economics of nuclear power plants Research Areas:
Dynamic Human Reliability Analysis (HRA):
- HUNTER: (Human Unimodel for Nuclear Technology to Enhance Reliability): A soft-ware tool built on plant operations proce-dures that will auto-calculate performance shaping factors during different scenarios, report has been released.
Risk-Aligned Data-Driven Inspections and Compliance Activities:
This effort has an objective to make licen-see's internal assessments and external in-spections more efficient by providing valuable insights into plant performance. The program will leverage infor-mation from Corrective Action Programs data to identify relevant performance trends. This pro-gram has been completed Risk-Informed Asset management The RISA team has developed an approach to employ artificial intelligence technologies to analyze plant records and extract quantitative information to support the modernized approach to equip-ment maintenance. The LWRS-developed tool enables the utilization of plant performance records to support data analyses targeting improved equipment maintenance. The program has been re-leased.
