being adversely affected. Regulatory Guide 1.27 describes design criteria and provisions which the ultimate heat sink must meet. Regulatory Guide 1.125 provides guidance on the use of physical models of hydraulic structures. Publications of the Corps of Engineers and USBR provide guidance for canal and reservoir design criteria. SRP Sections 2.4.3 through 2.4.7 provide basic hydrologic data for analyzing the hydraulic design of canals and reservoirs. Technical Rationale8 The technical rationale for application of these acceptance criteria is discussed in the following paragraphs:9 1. Compliance with GDC 1 requires that structures, systems, and components important to safety be designed, fabricated, erected, and tested to quality standards commensurate with the importance of the safety functions to be performed. GDC 1 applies to this SRP section because canals and reservoirs supply cooling water to structures, systems, and components important to safety for use during normal operations, anticipated operational occurrences, and accident conditions. Meeting the requirements of GDC 1 provides assurance that safety-related structures, systems, and components requiring cooling water will not lose the capability to perform their intended safety functions during the most severe credible natural phenomena in combination with normal operations, anticipated operational occurrences, or accident conditions.10 2. Compliance with GDC 2 requires that nuclear power plant structures, systems, and components important to safety be designed to withstand the effects of natural phenomena such as hurricanes, floods, tsunami, and seiches without loss of capability to perform their safety functions. This criterion further specifies that the design bases for these structures, systems, and components shall reflect the following: a. Appropriate consideration of the most severe natural phenomena historically reported for the site and surrounding area, with sufficient margin for the limited
