Content:
An example for a BWR is the Reactor Service Water System. The methodology for developing ITAAC for the interface requirements should be described in the DCD Tier 2 or certified information. Non-safety systems which cannot impact safety systems do not need Interface Requirements. Specific in-scope design details which preclude a non-safety system from impacting a safety system should be addressed in Tier 1. This is discussed further in Appendix A to this SRP section. xii. Accessibility for ISI Testing and Inspection. The accessibility does not have to be addressed in Tier 1, but should be addressed in Tier 2. The NRC does not intend to grant reliefs to the ISI requirements after design certification. xiii. Numeric performance values. Numeric performance values for SSC should be specified as ITAAC acceptance criteria to demonstrate satisfaction of a Design Commitment (DC). The numeric performance values do not have to be specified as DC and in the DD unless there is a specific reason to include them there. Key numbers and physical parameters used in the Chapter 6, 14.3, and 15 safety analyses and significant parameters of the PRA should be included in the DD. xiv. Normally, all design commitments in the DD Tier 1 should be verified by a specific ITAAC, unless there are specific reasons why this is not necessary. A single ITAAC may verify several design commitments. For example, the basic configuration ITAAC verifies the physical arrangement of the system using the design description and figures, in addition to verifications of other specific issues. 14.3-28 March 2007 B. Figures i. In general, figures and/or diagrams are required for all systems. However, a separate figure may not be needed for simple systems, structures, and components (e.g., the condenser). The format for the figures and/or diagrams should be simplified piping diagrams for mechanical systems. Symbols used on the figures should be consistent with the legend provided by the applicant. ii.
