Content:
[describe insights, including significant initiating events and accident sequences for core damage, releases from containment, and offsite consequences; core damage frequency, large release frequency, conditional containment failure probability, and offsite consequences; identification of areas in which features are the most effective in reducing risk (as compared to current operating plants); significant functions and contributors (e.g., hardware failures; structure, system, and component (SSC) unavailabilities; and human errors) to risk (as defined by core damage, containment releases, and offsite consequences); significant functions and contributors to maintaining plant safety to ensure that risk does not increase unacceptably; significant contributors to the uncertainties associated with the risk estimates; sensitivity of the estimated risk caused by potential biases in numerical values, assumptions, lack of modeling details, and previously raised safety issues; and accident classes that contribute to containment failure] 19.0-22 Revision 2 - June 2007
