al Design Criterion (GDC) 44, for CP and OL applications, as it relates to providing an ultimate heat sink for normal operating and accident conditions. Technical Rationale The technical rationale for application of these acceptance criteria to the areas of review addressed by this SRP section is discussed in the following paragraphs: 1. Compliance with 10 CFR 50.36 requires establishing appropriate limiting conditions for operation (LOCs) based on analyses and evaluations included in the SAR. LOCs define the lowest functional capability or performance levels of equipment required for safe operation of a facility. 2.4.14-5 Revision 3 - March 2007 As applied to SRP Section 2.4.14, technical specifications and emergency operation requirements need to be established if the design basis flood would have an impact on safety-related structures, systems, or components. In this case, the plant would be shut down before floodwaters reach an unsafe level and appropriate emergency procedures would be implemented by the licensee. Meeting the requirements of 10 CFR 50.36 provides a level of assurance that the nuclear power plant will be shut down and any necessary emergency measures taken before floodwaters reach an unacceptable level or any other water level, such as a critically low water level resulting from loss of water control structures, prolonged drought, tsunami, seiche, or any other cause relevant to the hydrology of the site. 2. Compliance with GDC 2 requires that SSC important to safety be designed to withstand the effects of natural phenomena such as earthquakes, tornadoes, hurricanes, floods, tsunami, and seiches without loss of capability to perform their safety functions. GDC 2 applies to SRP Section 2.4.14 because this section deals with actions specified in the technical specifications to shut down the plant and take appropriate emergency measures when the site is susceptible to flooding. This criterion also applies to measures needed to protect safety-related
