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.

NUCLEAR-COMPOSITE-1

Over 60 Years of New Nuclear Unit Design Experience

For over 60 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.
Read More on Our AP1000 Support

Sargent & Lundy is actively supporting Westinghouse Electric Company on several AP1000 projects, providing engineering and site support for the base plant and station-specific designs. Our activities include the evaluation/analysis and design of containment access platforms and associated structural steel framing, as well as the auxiliary building concrete structures.

Other key activities include the evaluation of structural modules for change impacts, along with qualification of electrical raceway supports and assessment of pipe rupture effects. Our code specialists have provided technical support to address ACI and AISC code compliance through compliance reviews and follow-up assistance to resolve any identified gaps.

We are providing project management, scheduling, and engineering support at the Westinghouse office in Cranberry, Pennsylvania, and engineering support at the Vogtle site.

  • 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).
Read More on Our UAE Nuclear Program Support

Sargent & Lundy is currently providing engineering and design services for the Barakah Nuclear Power Plant (BNPP), which is owned by Emirates Nuclear Energy Corporation (ENEC). The Barakah Site is currently under construction and is located in the western region of Abu Dhabi in the United Arab Emirates (UAE).

Sargent & Lundy has been supporting ENEC since 2010 by providing various engineering, consultancy, and site support services through a combination of local (in-country) engineering presence and traditional support from Sargent & Lundy’s Chicago Headquarters. BNPP features four APR1400 advanced pressurized water reactors and is targeted for a combined gross capacity of approximately 5,600 MW. The first unit is tentatively scheduled to begin commercial operation in May 2017.

The site design is based on the Korean Reference Plant (Shin-Kori site), designed and built by Korea Electric Power Corporation (KEPCO).

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 79 of the 99 operating nuclear units in the U.S., 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
  • Cyber Security
    Providing guidance to our clients to streamline the process for addressing the application of cyber security controls on a plant’s digital assets is part of our competencies. Specific analysis is performed in accordance with the requirements of 10 CFR 73.54 and Nuclear Energy Institute (NEI) 08-09 and 13-10 to determine the required protection from cyber-attacks up to and including the design basis threat as described in 10 CFR 73.1.Plants, including those with no digital safety-related systems, can have hundreds if not thousands of critical digital assets (CDAs). Our teams can assist with Cyber Security Plan (CSP) program implementation and ongoing compliance activities. Additionally we can support licensees with the planning and implementation of cyber security controls on existing CDAs and new CDAs added by digital upgrades.
  • Digital Control System Upgrades
    Our approach to providing digital upgrade engineering services is based on over 30 years of experience and working with a variety of vendors. We can prepare comparative analyses of digital systems to evaluate equipment options considering costs and functionality as well as create digital system conceptual design reports that determine funding costs and equipment specificity for the hardware system specification. Other services include hardware and functional specifications for the procurement of the digital control system. For modification work, we prepare full scope design change packages including installation of the replacement system.

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

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.

Open-Phase Solutions

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.
