APPLICATION OF THE GRADED APPROACH. Hazard Category 3 facilities
may not have the potential for resulting in significant radiological consequences beyond
the immediate facility. Therefore, the descr iption of site characteristics, as a minimum,
locates the facility on the overall site, shows the facility boundaries, and identifies any
other facilities that can significantly impact the facility being examined. For Hazard
Category 3 facilities, onsite meteorological conditions, hydrology, population information,
and offsite accident pathways are not typically required, since consequences are limited to
the facility itself. Note, however, that if significant chemical hazards are present in a
Hazard Category 3 facility that have the potential to cause significant offsite consequences,
more information is necessary.
For Hazard Category 2 facilities the emphasis of site characteristics description is focused
within site boundaries unless hazards have the po tential to cause offsite consequences of
concern. For Hazard Category 2 facilities with the potential for an accident resulting in
consequences of concern at the site boundary, site characteristics information is extended
beyond the site boundary to support assessment of population dose, land contamination,
and emergency planning external to the site.
C ONTENT G UIDANCE FOR SECTIONS OF C HAPTER 1
This section provides an introduction to the contents of this chapter based on the
graded approach and includes objectives and scope specific to the chapter as
This section lists the design codes, standards, regulations, and DOE Orders that
have been used for establishing the safety basis of the facility. The intent is to
provide only the requirements that are specific for this chapter and pertinent to the
safety analysis, and not a comprehensive listing of all industrial standards or codes
or criteria. Standards and Requirements Identification Documents (SRIDs) may be
referenced as appropriate.
This section describes the site boundary and facility area boundary.
This section provides basic geographic information, such as:
State and county in which the site is located.
