protection; waste management; or radiological protection of workers, the public, and the

environment. [10 CFR 830.3]

561.

SAFETY MANAGEMENT SYSTEM. An integrated safety management system established

consistent with 48 CFR 970.5204-2. [10 CFR 830.3]

562.

SAFETY MANAGEMENT SYSTEM (SYSTEM). Means an integrated safety management

system developed in accordance with the provisions of Department of Energy Acquisition

Regulations in 48 CFR 970.5204-2 (also described in the DOE P 450.4, "Safety Management

System Policy," issued on October 15, 1996). [48 CFR 970.5204-2]

563.

SAFETY PROGRAMS. Programs, required by DOE or other regulatory authority or

committed to in the contractor's Safety Management System description, which will be adhered

to for a scope of work by a facility or site in support of the work. [Generalized from DNFSB

input to apply to non-nuclear facilities] [DOE G 450.4-1B]

564.

SAFETY SIGNIFICANT STRUCTURES, SYSTEMS, AND COMPONENTS. The

structures, systems, and components which are not designated as safety class structures,

systems, and components, but whose preventive and mitigative function is a major contributor to

defense in depth and/or worker safety as determined from safety analysis. (See Safety Class

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

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

565.

SAFETY SIGNIFICANT STRUCTURES, SYSTEMS, AND COMPONENTS (SAFETY-

SIGNIFICANT SSCs). Structures, systems, and components which are not designated as

safety-class SSCs but whose preventive or mitigative function is a major contributor to defense

in depth and/or worker safety as determined from safety analyses. [10 CFR 830]

As a general rule of thumb, safety-significant SSC designations based on worker safety

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
