uired to change the information, and the statement may be added to each Tier 2* area in the DCD as appropriate for clarity. IV. Tier 1 information A third section of the DCD is the Tier 1 information. This information consists of an introduction to Tier 1, certified design descriptions, figures, and corresponding inspections, tests, analyses, and acceptance criteria (ITAAC) for systems and structures of the design, design material applicable to multiple systems of the design (referred to as design acceptance criteria or DAC), significant interface requirements, and significant site parameters for the design. The information in the Tier 1 portion of the DCD is extracted from the detailed information contained in the application for design certification. While the Tier 1 information must address the complete scope of the design to be certified, the amount of design information is proportional to the safety-significance of the structures and systems of the design. 1. Introduction to Tier 1. This section of Tier 1 includes definitions of terms and a listing of general provisions that are applicable to all Tier 1 entries. A. Definitions. This section defines terms used in Tier 1 that could be subject to various interpretations. The intent is to be consistent and as closely aligned as possible with the terminology in the SSAR, in common industry use, industry codes and standards, and NRC regulations, and guidance. Thus, should questions on terminology arise, these references would aid in understanding the intent of the information in Tier 1. Although not all-inclusive, the following definitions that apply to terms used in the Design Descriptions and associated ITAAC are acceptable: i. Acceptance Criteria means the performance, physical condition, or analysis result for a structure, system or component that demonstrates the Design Commitment is met. ii. Analysis means a calculation, mathematical computation, or engineering or technical evaluation. Engineering or technical
