at the initial design criteria and bases have been appropriately implemented in the final design as set forth in the final SAR. 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 assureensure 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 conditions. 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 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 ASBEMCB evaluates the system design information and drawings and, utilizing 40 engineering judgment, operational experience, and performance characteristics of similar, previously approved systems, to verify that: a. The system is capable of fulfilling the requirements of the facility for makeup water on a day-to-day basis. b. The component redundancy necessary for the system to perform its design function is provided. c. The potential for leakage and accidental spills has been minimized. d. Instrumentation (e.g., a conductivity monitor) has been provided together with the capability to isolate the system should planned operating conditions be exceeded. e. Piping has been provided as necessary to direct solutions and regenerative wastes to the radwaste system or other specified areas for processing and disposal. 2. The ASBEMCB also verifies, with input from the CMEB as requested, the following: 41
