important to safety. If a hazard exists that may lead to flooding of SSC important to safety, it should be documented and included in the design bases of affected facilities. 7. Consideration of Other Site-Related Evaluation Criteria: The potential effects of site-related proximity, seismic, and non-seismic information as they relate to flooding due to upstream dam failures and loss of safety-related water supply due to blockages and failures of downstream dam failures adjacent to and on the plant site and site regions are needed to meet the requirements of GDC 2, 10 CFR 52.17, and 10 CFR Part 100. 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 GDC 2 requires that nuclear power plant SSC important to safety be designed to withstand the effects of natural phenomena such as earthquakes, tornados, hurricanes, floods, tsunami, and seiches without loss of capability to perform their safety functions. The criterion further specifies that the design bases for these SSC 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 accuracy, quantity, and time period in which the historical data have been accumulated; B. Appropriate combinations of the effects of normal and accident conditions with the effects of the natural phenomena; and C. The importance of the safety functions to be performed. This criterion is applicable to SRP Section 2.4.4 because it specifies the hydrological phenomenon (i.e., flooding associated with dam failure) addressed in this section. In general terms, it also specifies the level of conservatism that should be used to assess the severity of the flood for the purpose of determining the design bases for SSC important to safety.
