thstanding the effects of earthquakes. Acceptance is based on meeting the guidance of Regulatory Guide 1.29, Position C-l, if any portion of the system is deemed to be safety related, and Position C-2 for nonsafety-related functions. 2. General Design Criterion 5 "Sharing of Structures, Systems, and Components, in regard to the effect of sharing in multiple-unit facilities. III. REVIEW PROCEDURES The procedures set forth below are used during the construction permit (CP) application review to determine that the design criteria and bases and the preliminary design as set forth in the preliminary safety analysis report meet the acceptance criteria given in subsection II. For the review of operating license applications, the review procedures and acceptance criteria are utilized to verify that the initial design criteria and bases have been appropriately implemented in the final design as set forth in the final safety analysis report. Upon request from the primary reviewer, the coordinating review branches will provide input for the areas of review stated in subsection I. 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 DWMS or portions thereof are safety related, including whether a seismic Category I makeup source is required for safe shutdown or for accident condi- tions. In confirming this design aspect, an analysis is made in which it is assumed that any DWMS pipe fails or component malfunctions or fails in such a manner as to cause maximum damage to other equipment located nearby. The -9.2.3-3 Rev. 2 - July 1981 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 ASB evaluates the system design information and drawings and,
