esign information is not available. The DAC are part of the Tier 1 information. Design certification document (DCD) - The master document that contains the information that is referenced by the design certification rule. The DCD includes both the Tier 1 information that is certified by the design certification rule and the Tier 2 information that is approved by and supports the rule. The DCD is composed of the certified design material and the non- proprietary version of the SAR, including all material incorporated by reference. Design margin - The additional performance capability above required standard basic system parameters that may be specified by a system designer to compensate for uncertainties. Design process - Technical and management process that commence with identification of design input and lead to and include the issuance of design output documents. [ASME Std NQA-1-1994] Design output - Documents, such as drawings and specifications, that define technical requirements of structures, systems, and components (ASME Std NQA-1, “Quality Assurance Requirements for Nuclear Facility Applications”). For software, design outputs are the products of the development process that describe the end product that will be installed in the plant. The design outputs of a software development process include software requirements specifications, software design specifications, hardware and software architecture designs, code listings, system build documents, installation configuration tables, operations manuals, maintenance manuals, and training manuals. Design requirement - Specification or constraints on the design of a system or system component. [IEEE Std 610.12-1990] Deterministic timing - Timing is deterministic if the time delay between stimulus and response has a guaranteed maximum and minimum. Appendix 7-B-6 Revision 5 - March 2007 Differential Modes - Faults between the signal terminals that cause the potential of one side of the signal transmission path to
