Well-Managed and Understood Safety, Design, and Operational Margins Well Managed Margins OR.5 Station leadership establishes a culture that thoughtfully manages safety, design, & operational margins An “Enabler” CM.1 Plant equipment configuration is rigorously maintained and performance is consistent with design and licensing requirements CM.4 Processes that are used to control plant design bases are defined and validated Well-Managed and Understood Safety, Design, and Operational Margins The “Outcome” CM.2 Roles and responsibilities for establishing and maintaining licensing and design basis are understood and applied consistently CM.3 Day-to-day activities are conducted in a way that ensures operational and design margins are maintained

Design and Operating Margins Model Functional/Design Failure Greater than design basis range Design margin ( This is a prohibited range of operation and represents the additional conservative margin to account for uncertainties in design and construction ) Design or Tech Spec Basis Limit Analyzed transient range ( Design allows operation in the transient range. However operating restrictions consistent with the design, such as the magnitude and frequency of excursions into this range apply) Operating Point Limit Operating margin Allowed operating range ( The allowed operating range provides the normal margins operators use without violating setpoints ) Normal Operating Point

Evaluating Configuration Management Licensing Bases Plant specific requirements to ensure compliance with licensing and design assumptions. Design and Engineering Bases Fundamental requirements for SSC to ensure licensing bases are met. Design constraints to ensure owner’s requirements are met. Technical Requirements Parameters that define the function of performance of a given SSC. Parameters that ensure the design and engineering bases are met. Configuration control practices Licensing Bases Design and Engineering Bases Technical Requirements
