full-power operating conditions, this review should address the PRA results and insights of the plant-specific PRA. This review should ensure that the external events are properly evaluated, including evaluating the appropriateness of external events that are screened out, bounded, or incorporated into other evaluations (e.g., grouped events). For each external event evaluated, the staff should review the PRA to ensure that it appropriately identifies and describes the following aspects: i. Significant Core Damage Sequences and their numerical values C Significant core damage sequences C Significant external initiating events C Significant functions, SSCs, and operator actions C PRA assumptions and PRA-based insights C Results and insights from importance, sensitivity, and uncertainty analyses ii. Significant Large Release Sequences and their numerical values C Significant large release sequences C Significant external initiating events C Significant functions, SSCs, and operator actions C Containment performance C PRA assumptions and PRA-based insights C Results and insights from importance, sensitivity, and uncertainty analyses C. Events During Other Operating Modes For events occurring under conditions other than full power (e.g., low power and shutdown), this review should address the PRA results and insights of the plant- specific PRA. This review should ensure that the modes are properly evaluated, including evaluating the appropriateness of modes that are screened out, bounded, or incorporated into other modes (e.g., grouped modes). For each mode (other than full power) evaluated, the staff should review the PRA to ensure that it appropriately identifies and describes the following aspects: 19.0-15 Revision 2 - June 2007 i.
