Content:
iewer shall confirm that equipment credited for core cooling, including support systems, are not attached to the walls or ceiling of any structure credited as a protective barrier. The adequacy of the design features in protecting equipment from structural and shock damage should not be evaluated by the Staff reviewer. The adequacy of the design features to fulfill these protective functions is subject to Staff inspection. The Staff reviewer shall consider design features credited for the purpose of protecting core cooling design features from fire damage caused by the dispersal of jet fuel following an aircraft impact. Based on the applicant’s description of the location of equipment credited for core cooling, including necessary support systems, the Staff reviewer shall confirm that the applicant has identified design features or functional capabilities that keep fire from spreading to these locations. Based on the applicant’s descriptions of design features or functional capabilities, the Staff reviewer shall confirm that they satisfy review procedure III.9 of this SRP. The adequacy of the design features in protecting equipment from fire damage should not be evaluated by the Staff reviewer. The adequacy of the design features to fulfill these protective functions is subject to Staff inspection. Review of Design Features for Maintaining the Containment Intact If the applicant has not identified design features or functional capabilities to maintain core cooling under all aircraft impact scenarios, the Staff reviewer shall confirm that the applicant has identified design features or functional capabilities for maintaining an intact containment, i.e., that satisfy review procedure III.5 of this SRP. The Staff reviewer shall verify that the applicant has credited 19.5-8 Revision 0 – April 2013 the containment structure as a feature specifically designed such that it will not be perforated by the impact of a large commercial aircraft.
