White Paper: The Viability of Nuclear Plant Process Heat for Industrial Usage
Abstract: As discussed in “The Long-Term Strategy of the United States: Pathways to Net-Zero Greenhouse Gas Emissions by 2050,” the U.S. population is feeling the impacts of a changing climate. In 2021, the U.S. experienced historic droughts and wildfires in … Continue reading
White Paper: Microchip, Macro Shortage: What You Should Do
Abstract: The microchip shortage has affected the entire global economy, and the United States power industry is no exception. While there is some debate about how long the shortage will last, many analysts predict it will extend into the latter … Continue reading
White Paper: Carbon Capture Projects
Abstract: As global emission requirements for carbon dioxide (CO2) continue to become more stringent, existing and new thermal power projects, as well as industrial emitters, may look towards CO2 capture, utilization, and storage to remain viable and emission compliant. This … Continue reading
White Paper: Wind-to-Solar Conversion, Interconnection Queue Generator Modifications
Abstract: The interconnection application process for transmission operators, as regulated by the Federal Energy Regulatory Commission (FERC), generally takes between two and three years to complete from Sargent & Lundy’s experience. With the economics of renewable technologies continuously changing, developers … Continue reading
White Paper: Battery Energy Storage Systems Independent Engineering Due Diligence
Abstract As power markets and the generation mix continue to evolve in the United States and elsewhere, the need for flexible power systems increases. To achieve power system flexibility, developers of new power projects and owners of existing projects have … Continue reading
White Paper: Storm Surge and Wave Impact of Low-Probability Hurricanes
Abstract Hurricanes pose major threats to coastal communities and sensitive infrastructure, including nuclear power plants, located in the vicinity of hurricane-prone coastal regions. This study focuses on evaluating the storm surge and wave impact of low-probability hurricanes on the lower … Continue reading
White Paper: Forensic Analysis of Gas Turbine-Generator Shaft Failures Due to Possible Subsynchronous Resonance
Abstract During the beginning of the commercial operation of a natural gas power plant* in 2016, several units at a multi-unit station experienced problems. Event records showed excessive power oscillations in the subsynchronous range, at frequencies which corresponded to the … Continue reading
White Paper: Limitations of Steady-State Unbalanced Load Flow Software for Analysis of Induction Motor Behavior During Voltage Unbalance Conditions
Abstract With increasing levels of penetration of distributed energy resources (DER), there has been more focus in recent years on the assessment of the adequacy of distribution circuits. Three-phase distribution circuits have typically operated with high levels of unbalance. For … Continue reading
White Paper: Nuclear Plant Auxiliary System Modeling & Analysis for OPC
Abstract The analysis of open phase conditions (OPC) at nuclear power plants represents an analytically complex industry challenge. As part of Sargent & Lundy’s ongoing efforts to advance research to improve detection and mitigation analysis for all OPCs, the firm … Continue reading
White Paper: Fast Bus Transfers For Open Phase Analysis at Nuclear Power Plants
Abstract Open phase events, when undetected in a timely manner, can be detrimental to motors; and therefore, could result in loss of safety functions that are necessary for ensuring safe plant shutdown. Sargent & Lundy specializes in identifying, designing, and … Continue reading
