analytical modeling. Considerations should be based on engineering judgment of

possible effects and the potential added value of safety-significant SSC designation.

[Note: Safety-significant SSC as used in this Standard distinguishes a specific category

of SSCs other than safety-class SSCs. It should not be confused with the generic

modifier "safety significant" used in DOE orders.]

(See Safety Class Structures, Systems, and Components; Safety-Class Structures, Systems,

and Components; and Safety Structures, Systems, and Components) [DOE STD-3009-94]

566.

SAFETY STRUCTURES, SYSTEMS, AND COMPONENTS. Both safety class structures,

systems, and components and safety significant structures, systems, and components. (See

Safety Class Structures, Systems, and Components; Safety-Class Structures, Systems, and

Components; and Safety Significant Structures, Systems, and Components) [10 CFR 830]

567.

SAFETY STRUCTURES, SYSTEMS, AND COMPONENTS (SAFETY SSCs). The set of

safety-class structures, systems, and components, and safety-significant structures, systems, and

components for a given facility. (See Safety Class Structures, Systems, and Components;

Safety-Class Structures, Systems, and Components; and Safety Significant Structures, Systems,

and Components) [10 CFR 830][DOE G 433.1-1] [DOE-STD-3009-94]

568.

SAMPLE EQUIPMENT. Equipment, representative of a design, used to obtain data that are

valid over a range of ratings and for specific service conditions (environmental sampling

equipment, e.g., split spoon samplers) are not encompassed by this definition. [DOE O

5480.EIA] [EH62dd1]

569.

SECONDARY ENVIRONMENTAL MONITORS. Environmental monitoring equipment or

activities which, if degraded, will produce a more than minor disruption of a monitoring

program. An example of a minor effect would be the failure of a unit whose place in the

program is effectively duplicated by overlap between one or more other components. An

example of a more than minor effect would be the failure of sufficient units to preclude continued

coverage, or the failure of a unit which provides the only coverage for large areas, such as a

groundwater monitoring well. (See Continuous Air Monitoring, Monitoring, Performance

Monitoring, Personal Monitoring, Personnel Monitoring, Post-Accident Monitoring Equipment,

Primary Environmental Monitors, and Safety Class Monitoring Equipment) [DOE O 5000.3B]

SECRETARIAL OFFICER (SO). The head of a first-tier organization; a DOE Headquarters

employee reporting directly to the Secretary, Deputy Secretary or the Under Secretaries for
