derive conservative inventory values needs to be provided.
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 Hazard Analysis Results
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.
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 184.108.40.206.
