Helping Secure the Future of Nuclear Power and Technologies
Sargent & Lundy has been helping clients deliver clean, carbon-free energy since 1954. Nuclear power has been one of our core competencies with widely-recognized capabilities in engineering, design, analysis, compliance, project management, and more. Our leading-edge services address today’s emerging issues with cost-effective solutions for both new nuclear unit designs and upgrades to operating units.
Our cost-effective solutions are also available to support medical isotope production facilities, fuel fabrication facilities, decommissioning, Department of Energy (DOE) facility design, and behind-the-meter nuclear plant applications such as hydrogen generation, advanced data centers, and direct air capture.

Nearly 70 Years of New Nuclear Unit Design Experience
Sargent & Lundy has been actively involved in the licensing and design of new nuclear units and facilities for nearly 70 years. We offer a full range of services to help you execute your new plant project, including full-scope licensing support, site selection, environmental report development, engineering, design, field support, construction management, and comprehensive project management.
Our involvement with new nuclear units has been continuous throughout the history of nuclear generation. We have deep nuclear roots across the U.S., Asia, Europe, and the Middle East. Our involvement includes both small modular reactor (SMR) and advanced reactor design support.
Small Modular Reactor and Advanced Reactor Support
Sargent & Lundy works with multiple SMR (i.e., reactors of ~300 MWe or less) and advanced reactor suppliers to design, license, and site the next generation of nuclear power plants. Selected projects are highlighted below.
New Generation, Advanced Reactor Nuclear Plant Support
We’re working with multiple suppliers of new generation, advanced reactor nuclear power plants (i.e., ~1000 MWe reactors or larger) on design, licensing, and onsite construction support activities. Selected projects are highlighted below.
New Medical Isotope Facility and Fuel Fabrication Facility Support
Sargent & Lundy’s nuclear group is currently providing services to non-power clients in areas such as medical isotope production and fuel fabrication. Services include design, licensing, and site-selection. Selected projects are highlighted below.
Support for Leveraging Nuclear Plants to Achieve Net Zero Emissions
As a leader in the global energy industry, Sargent & Lundy continually strives to leverage new technologies that create innovative solutions to meet net-zero emissions goals set by global communities. Recognizing the value nuclear energy can contribute to net-zero goals, we’ve been working with industry stakeholders to develop new applications and uses for both nuclear thermal and electrical energy. These applications will help enable the long-term viability of the existing nuclear fleet and reduce the overall carbon footprint of the electrical generation and industrial industries.
We actively support the North American nuclear fleet’s desires to utilize thermal and electrical dispatching in new revenue-creating opportunities. These “behind-the-meter” applications include: hydrogen production, storage, transport, and use; direct air capture; and data processing centers. The projects range in size from small pilot demonstration projects to fully integrated nuclear plant applications. Project scopes comprise complete nuclear plant integration with the application facility design, including plant layouts, switchyards, substations, digital relaying, control room interface, etc., along with equipment specification of transformers, disconnects, switches, digital relays, tanks, re-boilers/heat exchangers, electrolyzers, pumps, and other essential components.
Leadership in Services to Operating Nuclear Units
Providing engineering services to operating nuclear units continues to be a top priority at Sargent & Lundy, and our depth and breadth of experience has made us leaders in operating unit support. We currently support 105 nuclear units across North America as well as other nuclear clients worldwide – a testament to the trust the nuclear industry has in Sargent & Lundy.
In North America, we are currently the Engineer of Choice at 87 of the 92 operating nuclear units in the U.S., plus 18 Canadian units, and regularly provide engineering services to nearly all domestic nuclear units. We serve as leaders in nuclear-related code committees, applying our experience to benefit the industry as a whole.
Our current nuclear services include:
- Hardware/Software Integration
- Strategic Digital Project Implementation Support
- 10 CFR 50.69 Risk-informed categorization and treatment of structures, systems and components for nuclear power reactors
- Technical Specification Surveillance Test Risk Informed Documented Evaluation (STRIDE) per NEI 04-10
Along with design engineering services, we have a seasoned group dedicated to providing O&M support services, including modification implementation, testing, procedures, and specialty engineering support.
Delivering the Nuclear Promise: This initiative, spearheaded by the Nuclear Energy Institute, is a significant collaboration across the nuclear industry to advance nuclear station safety, reliability, and economic progress. Senior leaders from Sargent & Lundy actively contribute their expertise to the development of industry best practice guidance that benefits the entire U.S. nuclear fleet.
Another significant emerging opportunity for the U.S. nuclear power industry is Subsequent License Renewal (SLR). Sargent & Lundy is engaged in industry initiatives to identify key technical issues for SLR and develop an effective approach to economically sustain plant operation beyond 60 years. Read More
