significant if the engineered controls were available and selected.

Consequences from normal operations are addressed in the Radiation

Protection, Hazardous Material Protection, and Waste Management chapters.

Guidance is provided in each chapter on the application of the graded

approach.

A common DSA format (chapter, title, and organization) for all

nonreactor nuclear facilities is desirable but not essential. A table is to be

provided by the preparer that indicates where the DSA requirements of 10

CFR 830 are addressed. Content needs to be flexible to allow for

different facility types, hazard categories, and other grading factors.

Facility descriptive material is intentionally split to emphasize structures,

systems, and components of major significance:

Chapter 2, "Facility Description," provides a brief, integrated overview of

the facility structures, syste ms, and components.

Chapter 4, "Safety Structures, Systems, and Components," provides

detailed information only for those structures, systems, and components

that are safety class and safety significant. This application of the graded

approach will provide for a significant reduction of DSA volume, while

maintaining a focus on safety.

The programmatic chapters, including Chapter 6-17 provide a summary

description of the key features of the various safety programs as they

related to the facility being analyzed. These chapters are not meant to be

used as the vehicle for the determination of adequacy of these programs.
