PURPOSE. The DSA Executive Summary provides an overview of the facility safety
basis and presents information sufficient to establish a top-level understanding of the
facility, its operations, and the results of the safety analysis. It summarizes the facility
safety basis as documented in detail in the remainder of the DSA. Expected prod ucts of
this summary, as applicable based on the graded approach, include:
Summary of the facility background and mission.
Overview of the facility including location and boundaries.
Description of the facility hazard category.
Summary of the results of the facility safety analysis including operational
hazards analyzed, DBAs, and significant preventive and mitigative features.
Summary of the acceptability of the facility safety basis.
Guide to the structure and content of the DSA (i.e., "road map").
APPLICATION OF THE GRADED APPROACH. This summary is intended as an
overview of the facility safety basis and presents information sufficient to provide a basic
understanding of the facility, operations, and results of safety analysis. It is prepared upon
completion of all the other DSA chapters since it predominately draws upon the
information in those chapters (see the Introduction and Figure 1-2). Information provided
should be top- level in nature and avoid reproducing the details of material documented in

FA C I L I T Y B A C K G R O U N D A N D M ISSION
This section identifies the facility for which the DSA has been prepared and
presents general information on the background of the facility as it relates to the
stage of facility life cycle. Clearly present the current mission statement for
which the DSA documents the safety basis (i.e., the purpose for which
authorization is sought).
Present any relevant information (e.g., short facility life cycle, anticipated future
change in facility mission, approved DOE exemptions) impacting the extent of
safety analysis documented in the DSA and briefly explain its impact in terms of
application of the graded approach.
