Permissible Values

Value	Title	Description	Examples	Failure Impact	Independence	Power Supply	Quality Requirements	Redundancy	Risk Informed	Safety Function	Seismic Qualification	Testing Requirements
CLASS_1E	Class 1E Safety Systems	Safety systems essential to emergency reactor shutdown and core cooling	reactor protection system, emergency core cooling		required	independent emergency power		required		essential to safety	required
SAFETY_RELATED	Safety-Related Systems	Systems important to safety but not classified as Class 1E	some support systems, barriers				enhanced			important to safety		extensive
SAFETY_SIGNIFICANT	Safety-Significant Systems	Systems with risk significance but not safety-related					graded approach		classification based on risk assessment	risk-significant
