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.
