Safety-Class Structures, Systems, and Components (Safety-Class SSCs)
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 DOE-HDBK-1188-2006 88 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. 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
