CFR Title: 

Content:
cope 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 which is different than the structure of Tier 2. Consequently, developing the design description entries for any one system should be based on the multiple DCD Tier 2 chapters having technical information related to that system. This approach should be discussed in Section 14.3, describing how the many design aspects of the SSCs in Tier 1 were derived. The emphasis in DCD Tier 2 Section 14.3 should be on discussing the level of detail in Tier 1. Acceptable approaches for selection of the top-level requirements for Tier 1 may be based on the safety significance of SSCs, their importance in various safety analyses, and their functions for defense-in-depth considerations. At a minimum, the section should include a discussion of how the following items were addressed in the selection of the Tier 1 material: i. Selection of design information from the various chapters of Tier 2. ii. Features or functions necessary to satisfy the NRC's regulations in 10 CFR Parts 20, 50, 52, 73, or 100. iii. Treatment of safety-related SSCs. iv. Treatment of important features and functions identified in the NRC's SRP. v. Important insights or assumptions from the probabilistic risk assessment vi. Treatment of severe accident design features. 14.3-21 March
