owns, that the as-built facility is in conformance with the certified design and applicable regulations. Unless specified explicitly, the figures are not indicative of the scale, location, dimensions, shape, or spatial relationships of as-built SSC. In particular, the as-built attributes of SSCs may vary from the attributes depicted on the figures, provided that those safety functions discussed in the Design Description pertaining to the figure are not adversely affected. Some features and components of the systems are addressed by the basic configuration ITAAC as discussed below: Keep-Fill Systems - These will be included in the design description when needed for the direct safety function to be achieved without damaging water hammer and verified by the configuration ITAAC. However, a separate functional test need not be performed because the keep-fill system will be implicitly tested as part of the other system functional tests. Filters - Filters that are required for a safety function (such as Control Room HVAC radiation filtering) should be in the design description. The configuration ITAAC will check that the filter is exists, but need not test the filter performance because changes in technology and performance requirements could occur that would modify the specific performance criteria necessary for the filter. Additionally, filter performance is verified by Technical Specification surveillances. Severe Accident Features - These features should be described in the design description and the configuration ITAAC will verify that they exist. The capabilities of the features need not be included in the ITAAC because the performance of these features in their design environment cannot be verified by in-situ testing.
