Further Analysis

DOE-STD-3014-96

Inputs:

The list of the release scenarios that contribute to the total release

frequency exceeding the release frequency evaluation guideline. (Derived)

The frequency of each such release scenario. (Derived)

Outputs:

The hazardous material source term for each of the listed release

scenarios.

The exposure level to the maximally exposed individual at or beyond the

site boundary for each of the listed release scenarios.

Further Analysis. No further analysis is envisioned by this standard. In the vast majority

3.7

of cases, analysis taken to this point should provide sufficient information and insights

upon which to base decisions regarding the need for preventive or mitigative actions to

reduce risk from aircraft crash. However, the standard recognizes that this may not

always be the case, and therefore does not preclude further analysis. Such an analysis

would likely be a formal probabilistic risk assessment incorporating features such as

evaluation of crash/impact/release frequencies and structural response by specific aircraft

type (rather than subcategory), development of probabilistic fragility curves for structural

response, and quantification of distributions representing the analyst's state of knowledge

concerning total population exposures, health effects, and cleanup area associated with

the release scenarios. Guidance on the methods for performing such additional analysis

is beyond the scope of this standard.
