Application Guidance.

DOE-STD-3014-96

Applicability. Exposure evaluation will be performed for all facilities for which the

7.3.1

frequency of release has been shown to exceed the release frequency evaluation

guideline.

7.3.2

Application Guidance. Exposure evaluation will be based on the results of the

structural response analysis performed in accordance with Chapter 6 and the

scenario development part of the release frequency evaluation performed in

accordance with Section 5.5. For each scenario considered, exposure evaluation

will consist of translating facility damage into a source term and exposure, based

on the interaction between the energy generated during the accident and the

facility hazardous material inventory. Exposures should be analyzed for receptors

corresponding to the exceeded guidelines, but need not be evaluated for receptors

for which the corresponding guidelines are met. Therefore, for cases in which

offsite guidelines are met, exposure evaluation may be restricted to onsite impacts

only.

source term (BST) development for exposure evaluation for radioactive

material releases will be consistent with the guidance provided in

DOE-HDBK-3010-94 (Reference 5), which is based on a five-component

linear equation:
