he Staff reviewers will not make any determinations of adverse impacts the AIA features may have on the rest of the plant design and operations. Other reviewers under other SRP sections will make this determination. Reasonably Formulated Aircraft Impact Assessment The Staff reviewer shall examine the summary description of the AIA and use review procedures III.1 and III.2 of this SRP to determine if it has been reasonably formulated. Review of Design Features for Core Cooling The Staff reviewer shall consider the design features credited by the applicant for core cooling, including front line systems and support systems. As part of core cooling, front line systems, support systems, and borated water may be required to maintain the core with sufficient shutdown margin. The Staff reviewer shall examine the description provided by the applicant and confirm that it describes or references descriptions of the key design features and functional capabilities of all equipment credited in the heat removal path. Features shall be provided that are capable of removing heat immediately following shutdown from full power operation and when the plant is shutdown with the reactor in a cold shutdown (non-flooded) condition with a large vent in the primary system. The Staff reviewer shall apply review procedure III.4 of this SRP. The Staff reviewer should not attempt to verify whether or not design features for core cooling satisfy core 3 Consideration of Aircraft Impacts for New Nuclear Power Reactors, 74 FR 28120 (June 12, 2009). 19.5-7 Revision 0 – April 2013 cooling success criteria for beyond design-basis events (documented in the probabilistic risk assessment). The adequacy of the design features to fulfill these protective functions is subject to Staff inspection. Using information provided by the applicant, the Staff reviewer shall determine if the features identified are designed to cool the reactor core in the presence of a breach of the reactor coolant system. If not,
