Hazard Evaluation

This subsection presents, in summary fashion, the ba sic approach and guidance

used for generating the largely qualitative consequence and likelihood

estimates in hazard evaluation. Reference detailed guidance as necessary.

Additionally, present any screening logic used for binning accidents. The

appropriateness of the overall methods used to evaluate hazards is presented

and justified. This justification focuses on the selection of a technique for

given processes, not justification from first principles of standard analysis

methods, such as HAZOP.

3.3.2.1

Hazard Identification

This subsection presents the results of the hazard identification activity, either

by direct inclusion of or by reference to the hazard identification data sheets.

As a minimum, provide a summary table identifying hazards by form, type,

location, and total quantity. The attributes of hazards identified in this section

are the basis for subsequent hazard evaluation and accident analysis. Include

in the basic set of hazards identified radionuclides, hazardous chemicals,

flammable and explosive materials used or potentially generated in facility

processes, and any mechanical, chemical, or electrical source of energy that

may influence accident progression involving such materials.

To provide a perspective on facility hazards, summarize in this subsection the

major accidents or hazardous situations (e.g., fires, explosions, loss of

confinement) that have occurred in the facility's operating history. Specific

details on each occurrence are not required. A general summary by type with

emphasis on the major occurrences will suffice.

3.3.2.2

Hazard Categorization

This subsection presents the results of the final hazard categorization activity

specified in DOE-STD-1027. Include the facility hazard categorization and,

where segmentation has been employed, the segment boundaries and

individual segment classifications. Justify any segmentation in terms of

independence. Where facility segmentation is used, provide the hazard

breakdown by segment in the summary table required in Section 3.3.2.1.
