DOE-STD -3009-94

Executive Summary

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

subsequent chapters.

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.
