ation. Tier 2 contains information reviewed by the staff which is the basis for the staff's safety determination for the design. Therefore, the information in Tier 2 describes an acceptable means, but not the only means, of satisfying an ITAAC. Inspections are defined in the Introduction, and include visual and physical observations, walkdowns or record reviews. The inspections required for the "Basic Configuration Walkdown" ITAAC invoke the general provisions contained in the Introduction for as-built structures and systems. Tests are defined in the Introduction, and mean the actuation, operation, or establishment of specified conditions to evaluate the performance or integrity of the as-built SSCs. This includes functional and hydrostatic tests for the systems. The preferred means to satisfy the ITAAC is in-situ testing, where possible, of the as-built facility. The term "as-built" is intended to mean testing in the final as-installed condition at a facility. The term "type tests" is used in this column to mean manufacturer's tests or other tests that are not necessarily intended to be in the final as-installed condition. The results of pre-operational tests can be used to satisfy an ITAAC. However, the pre-operational tests described in DCD Tier 2 Section 14.2 or RG 1.68 are not a substitute for ITAAC. Where testing is specified, appropriate conditions for the test should be established in accordance with the Initial Test Program (ITP) described in Tier 1, DCD Tier 2 Section 14.2, and RG 1.68. Conversion or extrapolation of the test results from the test conditions to the design conditions may be required to satisfy the ITAAC. 14.3-19 March 2007 Analyses are defined in the Introduction, and may refer to detailed supporting information in the DCD Tier 2, simple calculations, or comparisons with operating experience or design of similar SSCs. The details of the analysis method should be specified in either the ITAAC or Tier 2 (preferred). The ITAAC should not
