DOE-STD-3014-96
equipment in the vicinity of the postulated impact, the analysis should proceed to
the next step.
Inputs:
a.
The structural screening guideline. (Defined)
b.
Mass (for aircraft and aircraft engine) and speed data for the
candidate aircraft categories/subcategories identified in Section 3.2.
(Defined partially in References 1 and 2 of Chapter 5)
c.
Structural design information for the facility. (Available from existing
facility design documents)
d.
A list of building-supported equipment whose failure could result in a
release (safety-related equipment) and its locations. (Available from
existing facility safety analyses)
e.
The location of hazardous material within the facility and accident
scenario information. (Available from existing facility design,
operation, and safety analysis documents)
Outputs:
a.
A list of impact locations and/or aircraft categories/subcategories that
can be screened out from further evaluation.
Structural Evaluation. The structural response evaluation step consists of
3.3.2
determining the type and extent of damage (local damage, excessive structural
deformation, and/or SSC functional failure due to vibration) to the facility when
subjected to impacts from aircraft subcategories that were identified in the
previous step as contributing to an annual impact frequency greater than the
frequency guideline. The results of the response analysis are reported as the
damage status for systems and structures, including confinement barriers,
meaning the level of damage an aircraft causes. In the case of individual
components, the damage status is limited to operable/nonoperable. Each aircraft
subcategory may be represented by a surrogate aircraft design for the purpose of
structural response evaluation. This surrogate aircraft design provides design
parameters such as aircraft mass, mass distribution, impact velocity, cross-
