ion report. Similar ITAAC to the example above may also be used for other SSCs with seismic and dynamic qualification requirements. In some instances, the ITAAC listed in SRP Section 14.3, Appendix D, were used to verify the dynamic qualification (e.g., seismic, loss-of-coolant accident, and safety relief valve discharge loads) of Seismic Category I mechanical and electrical equipment (including connected instrumentation and controls) in the design descriptions and figures. The inspection mentioned in the ITA above verifies the capability of mechanical and electrical equipment in their as-built condition, including anchorages, to perform their safety functions during and following an SSE. The Tier 1 information describing dynamic qualification of equipment may be considered for designation as Tier 2*, although specific provisions in the ITAAC, such as use of ASME QME-1-2007 (or later edition accepted by NRC) as accepted in RG 1.100 (Revision 3 or later revision), for the dynamic qualification of mechanical equipment may eliminate the need to use this designation. Tier 2* information is addressed further in SRP Section 14.3, Appendix A. Detailed supporting information for dynamic qualification requirements, including seismic qualification records, should be included in DCD Tier 2, Chapter 3. E. Environmental Qualification. The ITAAC should verify the environmental qualification of electrical and mechanical equipment in each system within the scope of ITAAC for the nuclear power plant. 14.3.3−13 Draft Revision 1 – September 2018 (1) Electrical Equipment Environmental Qualification. In the electrical equipment environmental qualification ITAAC, the Design Commitment should specify that the system’s Class 1E electrical equipment located in a harsh environment, including its connection assemblies, withstands the design basis harsh environmental conditions experienced during normal operations, anticipated operational occurrences, design-basis accidents, and
