LWRS Status Highlights
Program Mission The 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 have 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 Plant Modernization Pathway Main Goal: enable plant efficiency improvements through a strategy for long-term modernization Latest Report:
Integrated Operations for Nuclear Business Operation Model Analysis and Industry Validation Rev 1-This report presents 9 work reduction opportunities (condition-based maintenance, digital I&C and digital control room, automated planning and scheduling, advanced training technology, and remote assistance and automated troubleshooting, artificial intelligence assisted conditions reports analysis, drones and robotics, campaign maintenance and physical security) that can be implement in the current nuclear power plant fleet. Proposed ION Operations model Flexible Plant Operation & Generation (FPOG) Pathway Main Goal: enable diversification and increase revenue of light water reactors to produce non-electrical products

Page 2 Materials Research Pathway Main Goal: understand and predict long-term behavior of materials in nuclear power plants Latest Reports:
Ultrasonic Model Based Interactive Reconstruction of Experimental Concrete Specimens at EPRI-this report present the development of an advanced image reconstruction algorithms to extend the limitations of current ultrasonic nondestructive evaluations (NDE).
The role of grain boundary oxides in the susceptibility to irradiation assisted stress corrosion cracking for high dose 304 stainless steel under pressurized water reactor relevant conditions-This report present a mechanism of irradiation-assisted stress corrosion cracking (IASCC) in high dose (neutron-irradiated) solution-annealed 304 stainless steel in PWR primary water environment and to propose mitigation strategies Risk Informed System Analysis (RISA) Pathway Main Goal: develop safety analysis methods and tools to optimize the safety, reliability, and economics of nuclear power plants Research Areas:
EMRALD-HUNTER: An Embedded Dynamic Human Reliability Analysis Module for Probabilistic Risk Assessment-This report presents the integration of two dynamic risk tools recently developed under the U.S. DOE LWRS Program. Event Modeling Risk Assessment using Linked Diagrams (EMRALD) is a software package for modeling and running dynamic probabilistic risk assessment. Human Unimodel for Nuclear Technology to Enhance Reliability (HUNTER) is a software tool for dynamically modeling human reliability analysis. These two software tools have been integrated as EMRALD-HUNTER to allow streamlined risk modeling of both plant system and human operator reliability.
Application of Margin Based Methods to Assess System Health-This report presents a integration for monitoring data into margin-based reliability models. This integration has been completed for several use cases driven by specific practical applications. Such cross-pathway activity targeted also the direct application of margin-based models on a specific system of an existing nuclear power plant where large amount of historic monitoring data is used to monitor asset and system health.
Graphical overview of the risk informed asset management (RIAM) project Page 3 Physical Security Pathway Main Goal: develop technologies and technical bases to optimize physical security Latest Report:
Evaluation of Physical Security Risk for Potential Implementation of FLEX using Dynamic Simulation Methods-This report provides an overview of lessons learned in applying a dynamic computational framework that links results from a commercially available FOF simulation tool, a commercially available thermal-hydraulic tool, and EMRALD to an operating commercial EMRALD attack scenario nuclear power plant.
New EPID for LWRS Activities The EPID G-2023-0003 Light Water Reactor Sustainability Program Activities has been created to keep track of the work load that the agency is using on LWRS activities. This non-billable EPID does not have a specific CAC code, therefore, we encourage the staff to send an approval request for the EPID along with the CAC code to their supervisors. The EPID/CAC should be only used to report the activities related to the program (e.g.
meeting planning/participation, technical collaboration, etc.) If you have any doubt feel free to contact Ramón L. Gascot or Jeffery Smith.
