Applies to the design, fabrication, and erection of steel safety-related structures and structural elements for nuclear facilities using the Allowable Stress Design method. The structures or structural elements subject to this Specification are those steel structures which are parts of the nuclear safety-related system or which support, house, or protect nuclear safety-related systems or components, the failure of which would impair the safety-related functions of these systems or components. Specifically excluded from this Specification are pressure retaining components, e.g.
