Content:
mation 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, the Staff reviewer shall initiate a review, as described below, to confirm that design features or functional capabilities that protect the reactor coolant system pressure boundary from structural damage have been identified and described in the application. In most cases, operators are expected to have some warning prior to damage so a reactor scram would be expected to occur prior to damage. However in other cases, damage could impair the ability of the reactor to scram. An assessment will be made of the potential for damage to prevent a scram should it have not previously occurred. The Staff reviewer shall initiate a review to confirm that design features are in place to protect equipment relied upon for reactor scram. The Staff reviewer shall consider the design features credited by the applicant for protection of core cooling design features from structural damage caused by the impact of a large commercial aircraft. 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 protect these locations. Based on the applicant’s descriptions of design features or functional capabilities, the Staff reviewer shall confirm that they satisfy review procedures III.5, III.7 and III.8 of this SRP. The Staff reviewer shall ensure that the applicant has addressed all potential impact locations around the perimeter of the structure housing the protected core cooling design features. The Staff reviewer 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
