7.3.2.2

Source Term Guidance for Hazardous Chemical Releases. Source term

development for exposure evaluation for hazardous chemical releases

will be consistent with the guidance provided in Appendix D, Section D.2.

7.3.3

Exposure Calculation. Once a refined source term has been developed based on

the structural response of the facility to the postulated aircraft impact, onsite and

offsite exposures can be reassessed in accordance with Section 7.2, "Exposure

Screening." If the offsite screening guideline (and the onsite screening guideline

when deemed necessary) is met by the refined source term, no additional analysis

of aircraft impact (i.e., meteorological dispersion and consequence assessment) is

required. If the offsite screening guideline (and the onsite screening guideline

when deemed necessary) cannot be met, additional analysis will be performed to

assess the consequences of the release. Additional guidance is provided in

Appendix D, Section D.1 (for radioactive material) and Section D.2 (for hazardous

chemicals) to aid the analyst in defining the release scenarios and selecting the

appropriate dispersion models and parameters. Notwithstanding the guidance

provided, credit will not be taken for evacuation or medical treatment of receptors,

or for passive or active mitigation due to building confinement and rubble effects.
