2. 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

3. 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

4. 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
