level alarms for the pressurizer relief tank have been provided. e. The tank should be located in such a manner that the rupture discs are not a missile threat to safety-related equipment. III. REVIEW PROCEDURES The procedures below are used in the construction permit (CP) review to deter- mine 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 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 assure that this review procedure is complete. 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. 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. 5.4.11-3 Rev. 2 - July 1981 2. The SAR is reviewed to determine that the rupture disks on the relief tank have a relief capacity at least equal to the combined capacity of the pres- surizer relief and safety valves. The reviewer determines
