r evaluates the DWMS to ensure that it will withstand the effects of natural phenomena and will be capable of providing water of reactor coolant purity for makeup to the reactor coolant and associated systems, as well as providing water for other systems. Meeting the requirements of GDC 2 provides assurance that equipment associated with the DWMS will operate under the most severe credible natural phenomena in combination with normal and accident conditions without loss of capability to perform its intended safety functions. 36 2. Compliance with GDC 5 requires that structures, systems, and components important to safety shall not be shared by nuclear power units unless it can be shown that such sharing will not significantly impair their ability to perform their safety functions, including, in the event of an accident in one unit, an orderly shutdown and cooldown of the remaining units. The requirements of GDC 5 are imposed to ensure that the shared use of the DWMS in a multiple-unit plant will not significantly affect the orderly shutdown and cooldown in one plant in the event of an accident in another. Meeting the requirements of GDC 5 provides assurance that the operation of DWMS equipment will not be significantly impaired if it is shared by multiple units of a nuclear power plant.37 III. REVIEW PROCEDURES DRAFT Rev. 3 - April 1996 9.2.3-6 The procedures set forth below are used during construction permit (CP) or early site permit38 application review to determine that the design criteria and bases and the preliminary design as set forth in the preliminary SAR meet the acceptance criteria given in subsection II. For the review of operating license (OL) or combined license (COL) applications, the review 39 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 SAR. Upon request from the primary reviewer, the coordinating review branches
