thout undue risk to the health and safety of the public, are designed to remain functional." This condition includes the loads from the postulated seismic event, itself, and also any associated system transients or dynamic effects resulting from the postulated seismic event. Piping Components - These items of a piping system such as tees, elbows, bends, pipe and tubing, and branch connections constructed in accordance with the rules of Section III of the ASME Code. Postulated Events - Those postulated natural phenomena (i e., OBE, SSE) postulated site hazards (i.e., nearby explosion), or postulated plant events (i.e., DBPB, LOCA, MS/FWPB) for which the plant is designed to survive without undue risk to the health and safety of the public. Such postulated events may also be referred to as design basis events. SSE - Safe Shutdown Earthquake - Defined in Section III(c) of Appendix A of 10 CFR Part 100 as that earthquake which is based upon an evaluation of the maximum earthquake potential considering the regional and local geology and seismology and specific characteristics of local subsurface material. It is the earthquake which produces the maximum vibratory ground motion for which certain structures, systems, and components are designed to remain functional. These structures, systems, and components are those necessary to assureensure: (1) The integrity of the reactor coolant pressure boundary. (2) The capability to shut down the reactor and maintain it in a safe shutdown condition, or (3) The capability to prevent or mitigate the consequences of accidents which could result in potential offsite exposures comparable to the guideline." This condition includes the loads from the postulated seismic event, itself, and also any associated system transients or dynamic effects resulting from the postulated seismic event. Service Limits - The four limits for the service loading as provided in the appropriate subsection of Section III, Division 1, of the ASME Code. 3.9.3-29
