Plume depletion during transport. As it is transported downwind, an aerosol plume

will be depleted by gravitational settling of particles. Because of the high density

of plutonium and its compounds, this depletion effect can be very significant in

reducing the dose. Therefore, a consequence model that accounts for plume

depletion by gravitational settling should be used. When analyzing consequences

of any postulated accidental criticality, any model selected should account for the

decay during transport of short-lived fission product gases.

Ground deposition. Following passage of a plume, the amount of plutonium

deposited on the ground will determine whether long-term intervention to minimize

the dose to the resident population will be required. The consequence model

selected should calculate ground deposition to support protective action planning.

9.2.2 Program Elements

Properties and characteristics of plutonium and its compounds must be considered in

formulating the emergency management program elements. Following are specific program

element considerations related to the hazardous properties of plutonium.

(a) Emergency Response Organization. The primary influence of plutonium's hazardous

properties on the Emergency Response Organization (ERO) is in the staffing of the

consequence assessment component. As will be discussed in e) below, staff should be

assigned to the ERO who are knowledgeable of and able to quantitatively evaluate the

radiological aspects of the hazard.

(b) Offsite Response Interfaces. The specific properties of the hazardous material do not

significantly affect the content of this program element.

classification of emergencies for plutonium facilities should be based on the predicted

consequences at specific receptor locations, as compared with numerical criteria for

taking protective action (total effective dose equivalent). The classification of the

postulated event or condition should be determined during the hazards assessment

process and the observable features and indications identified as Emergency Action

Levels (EALs) for that event/condition.

(d) Notification. The specific properties of the hazardous material do not significantly

affect the content of this program element.

(e) Consequence Assessment. As discussed in section 9.3.1 c) and e), models and

calculational methods used for consequence assessment should be appropriate to the
