the inspections, tests, and analyses, or to demonstrate compliance with the acceptance criteria may not be identified by the standard format for safety analysis reports or the SRP, but is required to be added to Tier 2 to show the intended methods of performance of the ITAAC. Examples of this information includes detailed design, inspection, and construction items such as welding processes, piping stress reports, and building construction reports contained in appendices to DCD Tier 2 Chapter 3 for the evolutionary standard designs. Other examples may include supporting information for design processes and design acceptance criteria (DAC) for selected areas of the design. 4. Section 14.3 of Tier 2 The top-level design information in Tier 1 is extracted from the more detailed design information in Tier 2. Section 14.3 of Tier 2 should provide the bases, processes and selection criteria used to develop the Tier 1 information. However, the section should contain no technical information not already presented in other sections of Tier 2. 14.3-25 DRAFT Rev. 0 - April 1996 Section 14.3 should contain a description of each section of Tier 1 and a discussion of its development. The following items should be addressed: a. A discussion of the scope of the certified design, the interfaces with the certified design, and the site parameters selected. b. A discussion of the scope and applicability of any definitions and general provisions. c. A discussion of the how the Design Descriptions were developed, and how the various inspections, tests, analyses, and acceptance criteria for design commitments were selected. d. A discussion of the development of any additional design material, including the justification for any design processes and design acceptance criteria (DAC) for selected areas of the design. e. A discussion of the Tier 1 commitments for the Initial Test Program and Design Reliability Assurance Program. The design descriptions may utilize a system-based structure
