elative to the 1 Consideration of Aircraft Impacts for New Nuclear Power Reactors, 74 FR 28120 (June 12, 2009). 19.5-5 Revision 0 – April 2013 actions required to address aircraft impact without the AIA rule in place (e.g., similar actions contained in operational programs in place at current operating reactor sites).2 4. The design features or functional capabilities that provide reactor core cooling or spent fuel pool cooling criterion to be satisfied if the design features or functional capabilities have been included in the design of the plant to perform that cooling function and can be operated with reduced use of operator action (i.e., they are not features that serve a different function in the design but could be used in an ad hoc fashion to perform the cooling function). 5. The “intact containment structure” criterion to be satisfied if the containment: (1) will not be perforated by the impact of a large, commercial aircraft used for long distance flights in the United States, with aviation fuel loading typically used in such flights, and an impact speed and angle of impact considering the ability of both experienced and inexperienced pilots to control large, commercial aircraft at the low altitude representative of a nuclear power plant’s low profile and, (2) maintains ultimate pressure capability, given a core damage event, until effective mitigation strategies can be implemented. Effective mitigation strategies are those that provide, for an indefinite period of time, sufficient cooling to the damaged core or containment to limit temperature and pressure challenges below the ultimate pressure capability of the containment as defined in Chapter 19 of the design certification document or Final Safety Analysis Report (FSAR), as applicable. 6. The “spent fuel pool integrity maintained” criterion to be satisfied if the impact of a large commercial aircraft on the spent fuel pool wall or support structures does not result in leakage through the
