Content:
Revision 3 – April 2014 provisions of the Code to compute stresses and stress limits. This guidance is designed to comply with GDC 1. Meeting the requirements of GDC 1 provides reasonable assurance that components and structures important to safety are capable of performing their intended functions. 3. GDC 2 requires, in part, that components and structures important to safety be designed to withstand the effects of natural phenomena such as earthquakes, tornadoes, hurricanes, floods, tsunami and seiches without loss of capability to perform their safety functions. The design bases for these components and structures shall reflect, among other things, appropriate combinations of the effects of normal and accident conditions with the effects of the natural phenomena. SRP Section 3.9.3 provides guidance for the staff's review of loading combinations, stresses and stress limits for the subject components and structures which are important to safety. These loading combinations include consideration of the effects of expected natural phenomena combined with the appropriate effects of normal and accident conditions. The stresses and stress limits (computed in accordance with the provisions of the Code) are evaluated for acceptance by the staff, to ensure that equipment is designed to withstand these conditions without loss of capability to perform their intended functions. This guidance is designed to comply with GDC 2. Meeting the requirements of GDC 2 provides reasonable assurance that components and structures important to safety are capable of performing their intended safety functions. 4. GDC 4 requires, in part, that the nuclear power plant structures and components important to safety be designed to accommodate the effects of, and to be compatible with the environmental conditions associated with normal operation, maintenance, testing, and postulated accidents, including LOCA. SRP Section 3.9.3 provides guidance for the staff's review of the subject components
