Defense-in-depth The term 'Defense-in-depth' as it applies to the area of nuclear science can be defined as ' An approach to designing and operating nuclear facilities that prevents and mitigates accidents that release radiation or hazardous materials. The key is creating multiple independent and redundant layers of defense to compensate for potential human and mechanical failures so that no single layer, no matter how robust, is exclusively relied upon. Defense-in-depth includes the use of access controls, physical barriers, redundant and diverse key safety functions, and emergency response measures. For further information, see Speech No. S-04-009, 'The Very Best-Laid Plans (the NRC's Defense-in Depth Philosophy).' '.
