Helping Secure the Future of Nuclear Power
Since 1954, nuclear power has been a core competency of Sargent & Lundy, with proven 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 design and upgrades to operating units.
Over 65 Years of New Nuclear Unit Design Experience
For over 65 years, Sargent & Lundy has been actively involved in the licensing and design of new nuclear units. We offer a full range of services to help you execute your new plant project, including full-scope licensing support, engineering, design, field support, 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. and globally, including work with Korea Electric Power Corporation on new unit development.
Some examples of current new unit projects include:
- Support for Westinghouse Electric Power Company on several AP1000 projects, with engineering, project management, and scheduling for the base plant and site-specific designs, including structural analysis and design and code compliance.
- Engineering and design services for the four Barakah Nuclear Power Plant APR1400 advanced pressurized water reactor units owned by Emirates Nuclear Energy Corporation, currently under construction in the United Arab Emirates (UAE).
Leadership in Services to Operating Nuclear Units
Engineering service to operating nuclear units has been a continuous top priority at Sargent & Lundy, and has made us leaders in this arena. As a firm currently supporting 106 nuclear units across North America and nuclear clients worldwide, we are trusted throughout the industry.
We are currently “Engineer of Choice” at 88 of the 96 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.
Examples of our current nuclear services involvement include:
- Post-Fukushima Safety Enhancements
- Open-Phase Solutions
- Implementing NFPA 805 Solutions
- Enhanced Maintenance Optimization
- Hydrogen Generation
Along with design engineering services, we have a seasoned group dedicated to providing O&M support services, including modification implementation and testing 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. Sargent & Lundy senior management is actively contributing their expertise to the industry development of best practice guidance that will benefit 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 on SLR
Post-Fukushima Safety Enhancements
We provide post-Fukushima mitigating strategy (FLEX strategy) implementations and seismic hazard reevaluation services. Additionally, we offer engineering support to licensees in preparation of their submittals for flooding hazards and assist with the design analysis and modifications associated with the hardened containment vent systems.
We are the leader in identifying, designing, and installing comprehensive solutions to the open-phase condition (OPC) issue. OPCs have occurred throughout the electric power industry on three-phase power systems. An open event can impact a plant during any operating mode, including nonoperational plants if fuel is still in the spent fuel pool. Although existing regulations have requirements for the onsite and offsite power systems to permit functioning of structures, systems, and components important to safety for any failures in the offsite power system, including a single failure in the onsite power system, OPCs were not specifically identified as an issue during the licensing reviews of current operating nuclear power plants. Our services include detection and mitigation analyses for all OPCs.
NFPA 805 Solutions
The National Fire Protection Association (NFPA) approved the 2001 edition of NFPA Standard 805, “Performance-Based Standard for Fire Protection for Light-Water Reactor Electric Generating Plants,” (NFPA 805) in January 2001. This alternate fire protection rule [10 CFR 50.48(c)] describes a new, risk-informed, performance-based standard for existing light-water nuclear power plants and introduces a more objective, data-driven method of making U.S. nuclear power plants safer. The NRC has modified its fire protection regulations to allow licensees to transition voluntarily to NFPA 805 in lieu of its existing fire protection licensing basis.
Sargent & Lundy has been engaged with numerous clients regarding the resolution and response to this industry issue. Our expertise includes the initial probabilistic risk assessment (PRA) analysis, regulatory support for submittal, modification identification, modification design and implementation, as well as providing support through final NFPA 805 transition and procedure updates. Our diverse staff of PRA engineers and design engineers as well as our Operations & Maintenance Support Services group work together to achieve a successful transition.
