QR-5300 General Requirements for a Qualication Program A qualication program for active mechanical equip- ment used in a nuclear power plant shall include the following: (a) qualication requirements; (b) a process to demonstrate that the equipment satises the qualication requirements by analysis, test, operating experience, or a combination of these; (c) evidence of successful completion of qualifi- cation; (d) a documentation le containing QR-5300(a), (b), and (c). The requirements to satisfy QR-5300(a), (b), (c), and (d) should be contained in the equipment qualication specication. In the qualication program, aging, qualied life, and margin shall be considered as described in the following paragraphs.
QR-5330 Margin. Margin shall be considered in the qualication program to account for variation in performance, errors in experimental measurements, and variations in commercial production, thereby providing a level of condence that the equipment can perform under the most adverse service conditions for which it is qualied. Other sections and Appendix QR-A provide additional guidelines on margins as required for metallic compo- nents. Additional guidelines on margins for nonmetallic components are provided in Appendix QR-B. In identifying margin, it is necessary to consider not only the accuracy of the design data, but also the dimensional tolerances for the parts and the accuracy of the instrumentation. In all cases, engineering judgment should be used to determine the adequacy of qualica- tion margins. This determination shall be appropriately documented. Examples of parameters that should be considered for appropriate margins are maximum or minimum external temperatures and pressures, radiation levels, electrical voltages and frequencies, operating time peri- ods, dynamic excitation (including vibration), and accu- racy of data and calculation methods.
QR-7321 Aging. As described in QR-7311, aging is not normally a signicant concern for metallic compo- nents; however, it should be one of the items considered: (a) analysis may be used to eliminate consideration of environmental stresses or aging effects that have an insignicant impact upon equipment functional integrity; (b) analysis may be used to extrapolate or otherwise account for the effect of equipment design modications as well as verication of aging or environmental parame- ters in instances when intended application exceeds prior qualication constraints. When analysis is used to simplify or extend equipment qualication, the analysis shall consider signicant aging mechanisms for the item, such as thermal, radiation, wear, and chemical. Analysis methods may be used in conjunction with supportive empirical data to simplify or supplant the test aging exercise for nonmetallic items.ASME QME-1 pdf download.
