Defense-in-Depth Philosophy
-An approach to designing and operating nuclear facilities that prevents and mitigates accidents that release radiation or hazardous materials-Multiple independent and redundant layers of defense to compensate for potential human and mechanical failures-no single layer, no matter how robust, is exclusively relied upon*Use of access controls*Physical barriers
- Redundant and diverse key safety functions*Emergency response measuresUSET Homeland Security and Emergency Services Committee 3

- NRC is singular authority for making decisions regarding overall adequacy of EP*Includes making a final determination whether EPZ extends beyond site boundary*Includes making a final determination of appropriate size of EPZ to adequately protect public health and safety*NRC makes this determination in consultation with FEMAUSET Homeland Security and Emergency Services Committee 15Emergency Planning Zones (EPZs)

Relationship between PAGs and EPZs
- PAGs are trigger for appropriate protective actions-Protect public health and safety
-Minimize exposure to general public and emergency workers
-Not to be used as acceptable dose limits
-PAGs and EPZs complement each otherUSET Homeland Security and Emergency Services Committee 17 Emergency Classification Levels
