rms to the design certification. The material in the DCD Tier 2 for each of the DAC areas should include, as appropriate, sample calculations or other supporting information to illustrate methods that are acceptable to the staff for meeting the Tier 1 DAC commitments. The DAC may be provided in Tier 1 as part of additional certified design material applicable to more than one system. If so, the structure of each area where DAC are used is the same as for the other areas of the design that are verified by ITAAC. The structure consists of three parts: the Tier 1 Design Description, the corresponding DAC, and the Tier 2 supporting information in the DCD Tier 2 for the DAC. The Design Description for each DAC should describe its scope and applicability to the SSCs of the design. Amplifying information on this Tier 1 information should be contained in DCD Tier 2 Section 14.3. Alternatively, applicants may choose to address all design issues appropriately in the SSCs to which they apply, so that no DAC are needed. For the two areas of rapidly changing technology, control room and remote shutdown system design (human factors), and digital computer-based instrumentation and controls design, the Design Descriptions and DAC delineate the process and requirements that a COL applicant or licensee should implement to develop the design information required in each area. Acceptance criteria are specified in Tier 1 for the development process at various stages of detailed design and subsequent construction and testing. The COL applicant or licensee is required to develop the procedures and test programs necessary to demonstrate that the DAC requirements are met at each stage. Similar to ITAAC, the COL applicant or licensee should certify to the NRC that the design 14.3-23 March 2007 through that phase is in compliance with the certified design. The NRC should review, audit, and inspect the work to confirm that the COL applicant or licensee has adequately implemented the
