Content:
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. All components discussed in the design description should be shown on the figure. iii. System boundaries with other systems should be clearly delineated in the figures. With few exceptions, system boundaries should occur at a component. iv. ASME code class boundaries for mechanical equipment and piping are shown on the figure and form the basis for the basic configuration check (system) that is required in each individual system ITAAC. The configuration check includes an inspection of the welding quality for all ASME Code Class 1, 2, and 3 piping systems described in the design description. A hydrotest is also required in each system ITAAC for ASME Code Class 1, 2, and 3 piping systems to verify the pressure integrity of the overall piping system, including the process of fabricating the system, and welding and bolting requirements. v. As a minimum, the instruments (pressure, temperature, etc.) required to perform Generic Technical Guidelines (e.g., ERGs, EPGs)(as described in the DCD Tier 2 Chapter 18) should be shown on the figures, or described in the DD. vi. The minimum inventory of alarms, indications, and controls, if established in the main control room or remote shutdown panel ITAAC, do not have to be discussed in individual DD's or shown on figures. Other "essential" alarms (e.g., associated with shutdown cooling system (SCS) high pressure (ISLOCA), SCS performance monitoring indications) not part of the minimum inventory should be shown on the figures. vii. Identification of all alarms, displays and controls on the remote shutdown panel should be included in the system diagram or alternatively in the remote shutdown panel ITAAC. viii. Class 1E power sources (i.e., division identification) for electrical equipment can be shown on the figure in lieu of including
