tems, 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 safety-related structures, systems, or components to the degree that they cannot perform their intended safety functions.26 III. REVIEW PROCEDURES The procedures below are used in the construction permit (CP) review to determine that the design criteria and bases and the preliminary design described in the SAR meet the acceptance criteria given in subsection II of this SRP section. For operating license (OL) reviews, the 5.4.11-5 DRAFT Rev. 3 - April 1996 procedures are used to verify that the initial design criteria and bases have been appropriately implemented in the final design. Upon request from the primary reviewer, the coordinating review branches will provide input for the areas of review stated in subsection I of this SRP section. The primary reviewer obtains and uses such input as required to assureensure that this review procedure is complete. 27 The reviewer selects and emphasizes material from this SRP section, as may be appropriate for a particular case. A determination will be made as to whether the pressurizer relief tank system or portions thereof are safety-related. In confirming this design aspect, an analysis is made in which it is assumed that any system pipe fails or component malfunctions or fails in such a manner as to cause maximum damage to other equipment located nearby. The system will be considered nonsafety-related if its failure does not affect the ability of the reactor facility to achieve and maintain safe shutdown conditions.28 1. The SAR is reviewed to establish that the pressurizer relief tank system description and related diagrams clearly delineate system operation and the system capability to accept the steam flow released from the pressurizer for step load decreases. 2. The SAR is reviewed to determine that the rupture disks on
