Researchers will perform a series of corrosion and stress corrosion tests on unirradiated alloys to determine the possibility of switching from LiOH to KOH to control the pH in nuclear reactors without worsening the corrosion behavior of the structural alloys used in pressurized water reactor core internal components. The impacts of such a change and the consequent water chemistry alterations on the corrosion processes and nucleaer power plant core-internal component service-life will be assessed and better understood.

Researchers will produce validation data for the heat pipe code, Sockeye, by measuring the internal thermal-hydraulic parameters of a single-heat pipe and the performance of an integrated multi-heat-pipe system in various operation scenarios. The results of this project will generate more liquid metal heat pipe validation data, which is currently lacking and needed to support micro-reactor design and licensing activities.

Researchers will evaluate the opportunities and challenges of operating micro-reactors in decentralized power generation applications and the potential for deployment in established micro-grids with diverse power generation sources. By using a well-characterized prototypic environment platform, the Modelica-based Hybrid Energy System, the market potential for deployment of micro-reactors on campuses and other similar existing micro-grids will be quantified.

Researchers will study the effect of surface microstructure, mechanical stress factors, and radiation damage on the corrosion response of stainless steel under two different alkaline pressurized water reactor primary water chemistry conditions. The project will involve investigation of mechanical stress factors such as strain rate, residual stress, deformation induced persistent slip bands, dpa damage, and fatigue cracks and modeling to understand the physical phenomena associated with the measured corrosion response and inform the U.S. nuclear industry regarding KOH.

Researchers will develop a method for identifying and prioritizing sources of uncertainty in external hazard probabilistic risk assessment for nuclear power plants, with particular emphasis on uncertainties associated with hazard characterization. External flooding wil be utilized as the demonstration hazard during this project, while a common taxonomy for communicating uncertainties across a broad range of external hazards will be created.

Researchers will develop an innovative, enhanced automation control framework for small modular reactors (SMRs) that supports control of multiple units operating in a variety of reactor core conditions. Through these enhancements, SMR technology gains improved marketability through potential deployment to a broader range of markets and can also lead to reduced operating and maintenance costs for a SMR site, increasing the overall profitability.

Researchers will explore how to leverage two key value propositions for small modular reactors (SMR) in shifting market conditions, in order to achieve widespread market deployment: (1) participation in small and large power and industrial markets and (2) cost reductions via mass fabrication. The result of this work will be advanced power system modeling, optimized SMR design with thermal storage for power and industry markets, and new SMR deployment pathways.

Researchers will identify fire parameters that have the largest impact on fire conditions, quantify those parameters contributing to uncertainties in the fire data through Monte Carlo simulation results, and use statistical analysis and machine learning models from the simulation results to assess existing data and recommend appropriate new fire tests to reduce uncertainties that are important to risk. With this information, researchers will develop a framework capable of determining the significant contributors to uncertainty in physical events that are relevant to the risk assessment and, then, determine the need for new experiments that would be of most value to reduce risk.
