SAFETY-CLASS STRUCTURES, SYSTEMS, AND COMPONENTS (SAFETY-

CLASS SSCs). Systems, structures, or components including primary environmental

monitors and portions of process systems, whose failure could adversely affect the

environment, or safety and health of the public as identified by safety analyses. (See

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

Systems, and Components; and Safety Structures, Systems, and Components) [DOE

5480.30]

For the purpose of implementing DOE-STD-3009-94, the phrase "adversely affect"

means Evaluation Guidelines are exceeded. Safety-class SSCs are systems, structures, or

components whose preventive or mitigative function is necessary to keep hazardous

material exposure to the public below the offsite Evaluation Guidelines. The definition

would typically exclude items such as primary environmental monitors and most process

equipment. [DOE-STD-3009-94]

548.

SAFETY CONTROLS. Safety significant controls or safety class controls (see also

administrative controls). [DOE G 450.4-1B]

549.

SAFETY DOCUMENTATION. Reports, memoranda, and other signed and dated

documents that identify the hazards of a process or facility and describe measures for

their control. (See DOE O 5480.23.)

SAFETY ENVELOPE. The range of conditions covered by the safety documentation of

550.

a process or facility under which safe operation is adequately controlled. [DOE G 450.4-

1B]

SAFETY EVALUATION. A safety evaluation is that record required by DOE O

551.

5480.21 to document the review of a "change." This document records the scope of the

evaluation and the logic for determining whether or not an Unreviewed Safety Question

exists. (See Final Safety Analysis Report, Preliminary Documented Safety Analysis,

Preliminary Safety Analysis Report, Safety Analysis Report, Safety Basis, and Safety

Evaluation Report) [DOE O 5480.21] [EH62dd1]

SAFETY EVALUATION REPORT. The report prepared by DOE to document

552.

A. The sufficiency of the documented safety analysis for a hazard category 1, 2, or 3
