Examples of acceptable Tier 1 information may be found in the DCDs for the evolutionary designs. I. DESIGN DESCRIPTIONS AND FIGURES A. DESIGN DESCRIPTIONS The following information should be included in the various Design Descriptions in a consistent order. 1. System purpose and functions (minimum is safety functions, may include some non- safety functions) The DD identifies the system's purpose and function. It captures the system components that are involved in accomplishing the direct safety function of the system. Each DD should include wording (preferably in the first paragraph) that identifies whether the system is safety-related or is a non-safety system. Exceptions should be noted if parts of the system are not safety-related or if certain aspects of a non-safety system have a safety significance. 2. Location of system The building that the system is located (e.g., containment, reactor building, etc.) shall be included in the DD. 3. Key design features of the system The design description should describe the components that make up the system. Key features such as the use of the some of the safety relief valves to perform as the Automatic Depressurization System should be described in the DD. However, details of a components design, such as the internal workings of the
