ed in the following paragraphs:16 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. 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 (i.e., if the design of the plant is such that Regulatory Position 2 of Regulatory Guide 1.59 applies). 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.17 2. Compliance with GDC 2 requires that structures, systems, and components 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 equipment. Regulatory Guide 1.59 discusses the design basis floods that nuclear power plants should be able to withstand without loss of capability to achieve and maintain cold shutdown. Regulatory Guide 1.102 describes types of flood protection acceptable to the NRC staff and acceptable methods for protecting plants from the effects of probable maximum precipitation falling directly on the site.
