owing paragraphs:24 A. Compliance with GDC 2 requires that systems, structures, and components important to safety be designed to withstand the effects of expected natural phenomena, combined with the appropriate effects of normal and accident conditions, without loss of capability to perform their safety functions. The design of nonsafety-related equipment such as the pressurizer relief tank should be consistent with this objective. GDC 2 is applicable to SRP Section 5.4.11 because the reviewer verifies that the design of the pressurizer relief system is consistent with transient analyses of related or adjacent systems and that failure or malfunction of the pressurizer relief tank system will not adversely affect the performance, in accordance with applicable criteria, of safety-related structures, systems, or components. Meeting the requirements of GDC 2 provides assurance that the failure of the pressurizer relief tank system will not prevent structures, systems, and components important to safety from performing their intended safety function.25 B. Compliance with GDC 4 requires that components important to safety be designed to accommodate the effects of, and be compatible with, environmental conditions associated with normal operation, maintenance, testing, and postulated accidents, including loss-of- coolant accidents and dynamic effects such as pipe whip, missiles, and discharging fluids. The design of nonsafety-related equipment, such as the pressurizer relief tank should be consistent with that design objective. GDC 4 is applicable to SRP Section 5.4.11 because the reviewer verifies that failure of the pressurizer relief tank system will not generate missiles or adverse environmental conditions that could result in damage to safety-related structures, systems, or components. Meeting the requirements of GDC 4 provides assurance that the pressurizer relief tank system will not generate missiles or cause adverse environmental conditions that could damage
