escribed in column 1. In situ testing of the as-built SSCs is the preferred method of ITAAC verification. The detailed design information in the COL FSAR should include supporting information for each ITAAC, which describes at least one method that can and should be used to satisfy the ITAAC acceptance criteria. This information describes an acceptable means (albeit not the only means) of satisfying an ITAAC. The following describes the methods used to verify the design commitment: a. “Inspect” or “inspections” include visual observations, physical examinations, or reviews of records based on visual observation or physical examination that compare the SSC condition to one or more design commitments. Examples include walkdowns, configuration checks, measurements of dimensions, or nondestructive examinations. b. “Test” means the actuation, operation, or establishment of specified conditions to evaluate the performance or integrity of the as-built SSCs, unless explicitly stated otherwise. In situ testing, where possible, of the as-built facility is the preferred means of ITAAC verification. Conversion or extrapolation of test results from the test conditions to the design conditions may be necessary to satisfy the ITAAC. The licensee or applicant should provide suitable justification for and applicability of any necessary conversions or extrapolations of test results necessary to satisfy the ITAAC. c. “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 components. d. “Analysis” means a calculation, mathematical computation, or engineering or technical evaluation. Engineering or technical evaluations could include, but are not limited to, comparisons with operating experience or design of similar SSCs. The details of the required analysis should be specified in either the ITAAC or preferably the
