Services to Improve Your Competitive Edge
Sargent & Lundy provides complete operations & maintenance (O&M) and plant engineering support services for new-generation and operating power plants and transmission and substation facilities. Our professionals have backgrounds in engineering, operations, maintenance, and testing. Our team members also serve on industry code committees and regularly attend and participate in industry users’ group meetings.
In support of the Nuclear Energy Institute Delivering the Nuclear Promise initiatives our senior management is collaborating with NEI, EPRI, INPO, and utility staff in planning and developing industry guidance documents. Senior staff members are contributing members of the engineering and preventive maintenance process (PMP) working group teams. An example of our approach to drive down maintenance costs and reduce outage scope is our enhanced maintenance optimization service (EMO). More About EMO
We can assist you with development of operating/maintenance/test procedures, plant engineering program support, valve technical support services, maintenance optimization/equipment reliability, life-cycle management, outage support, equipment condition assessments, spares program support, root cause analysis, and troubleshooting to improve your competitive edge.

Maintenance Optimization
Maintenance optimization means performing the right maintenance at the right time. We develop integrated predictive/preventive maintenance (PdM/PM) programs so that maintenance can be performed in a planned rather than a reactive mode. Integrating predictive technologies with optimized PM requirements reduces overall O&M costs while improving reliability.
Enhanced Maintenance Optimization (EMO): Our innovative EMO process goes beyond the template-driven or similar types of preventive maintenance optimization approaches typically used in the industry. EMO is an advanced method that integrates multi-discipline engineering know-how and addresses component aging to improve equipment reliability while reducing outage scope and maintenance costs.

Operation, Maintenance, and Test Procedures
For more than 20 years Sargent & Lundy has been developing/updating operating, maintenance, test, and other technical procedures to support operating and new-generation nuclear power plant projects. The Sargent & Lundy team has worked on thousands of procedures in support of our nuclear power customers, encompassing a variety of nuclear power plant vintages.
Our highly experienced staff offers backgrounds in engineering, operations, maintenance, testing, procedures, and plant programs. Some individuals are former utility staff members and previously licensed senior reactor operators (SROs). More about nuclear plant procedures support.
Valve Technical Support Services
Effective valve programs are key to the efficient and reliable operation of a power plant or facility. Valve programs improve reliability and control O&M costs. Our specialists work closely with clients to provide valve technical support services and innovative solutions for safe and reliable plant operation. Services include specification development, valve and actuator data sheets for valve set-up and diagnostic testing, valve maintenance optimization programs, maintenance and test procedures, and onsite technical support.
Condition Assessment
Sargent & Lundy was a pioneer in condition assessment for the power industry, leading the development of EPRI’s condition assessment guidelines for power plants and substations. Since that time, we have completed condition assessment assignments for more than 200 facilities. We review facility data, interview plant personnel, perform walkdowns, and apply extensive equipment and industry reliability knowledge to provide recommendations on maintenance, repair, and refurbishment or replacement. We also provide long-range testing and inspection plans for continued monitoring and planning.
