are limited to those systems, structures, or components whose failure is estimated to

result in a prompt worker fatality or serious injuries or significant radiological or

chemical exposures to workers. The term, serious injuries, as used in this definition,

refers to medical treatment for immediately life-threatening or permanently disabling

injuries (e.g., loss of eye, loss of limb).

The general rule of thumb cited above is neither an evaluation guideline nor a

quantitative criterion. It represents a lower threshold of concern for which safety

significant SSC designation may be warranted. Estimates of worker consequences for the

purpose of safety-significant SSC designation are not intended to require detailed

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.]

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]

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-

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.
