electrical power sources/divisions. The DD or figure should identify the electrical power source/division for the equipment included in the system. Independent Class 1E power sources are required for components performing direct safety functions and are needed to meet single failure criterion, GDC 17, etc. Electrical separation should also be addressed in the electrical and I&C systems ITAAC. 14.3-27 March 2007 x. Equipment to be qualified for harsh environments. Electrical equipment that is used to perform a necessary safety function should be demonstrated to be capable of maintaining functional operability under all service conditions, including LOCA, postulated to occur during its installed life for the time it is required to operate. Documentation relating to equipment qualification issues should be completed for all equipment items important to safety in accordance with the requirements of 10 CFR 50.49. The basic configuration standard ITAAC described in Appendix D to this SRP section verifies this aspect of the design. The scope of environmental qualification to be verified by the ITAAC includes the Class 1E electrical equipment identified in the Design Description (or on the accompanying figures), and connected instrumentation and controls, connected electrical components (such as cabling, wiring, and terminations), and the lubricants necessary to support performance of the safety functions of the Class 1E electrical components. The qualification of I&C equipment for "other than harsh" environments should be addressed in the I&C ITAAC. xi. Interface requirements. The interface requirements should be identified in the Design Descriptions for out of scope or partially out of scope systems and cross-referenced in a separate section of the certified information. 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
