amination that compare the structure, system, or component condition to one or more Design Commitments. Examples include walkdowns, configuration checks, measurements of dimensions, or non-destructive examinations. Test means the actuation or operation, or establishment of specified conditions, to evaluate the performance or integrity of as-built structures, systems, or components, unless explicitly stated otherwise. Type Test means a test on one or more sample components of the same type and manufacturer to qualify other components of that same type and manufacturer. A type test is not necessarily a test of the as-built structures, systems or components. 2. General Provisions This section of Tier 1 provides general provisions that are applicable to the design descriptions, figures, and the ITAAC. a. Verifications for Basic Configuration for Structures and Systems This section of Tier 1 includes provisions related to the verification of the ITAAC for basic configuration for systems and structures of the design. This ITAAC is contained in the buildings and most of the systems described in Tier 1. The ITAAC includes inspection of the functional arrangement of the system as described in the design description and as shown in the figures. It also includes, and is limited to, verifications of welding, environmental qualification, seismic DRAFT Rev. 0 - April 1996 14.3-18 qualification, and motor operated valves as described in the definitions and general provisions provided in the DCD Tier 1. b. Treatment of Individual Items A licensee is not prohibited from utilizing an item not described in Tier 1. However, the as-built facility must be consistent with the rule approving the design, including both tiers of information. The change process for the certified design is described in the design certification rule. The term "operate" as utilized in Tier 1 is intended to refer to the actuation and running of equipment. This is not meant to include the term "operable" in the
