emains cooled or the containment remains intact and spent fuel cooling or spent fuel pool integrity is maintained (the acceptance criteria). For some cases, when the damage could impair the ability of the reactor operator to scram the reactor, the applicants should assess the potential for damage to prevent a scram and confirm that design features are in place to protect equipment relied upon for reactor scram. Applicants are required to describe how such design features and functional capabilities meet the acceptance criteria of the rule. The impact of a large commercial aircraft is a beyond-design-basis event. Consequently, the NRC requirements that apply to the design, construction, testing, operation, and maintenance of design features and functional capabilities for design basis events do not apply to design features or functional capabilities selected by the applicant solely to meet the requirements of the AIA rule. The objective of the AIA rule is to require nuclear power plant designers to perform a rigorous assessment of the design to identify design features and functional capabilities that could provide additional inherent protection to withstand the effects of a large commercial aircraft impact (i.e., meet the rule’s acceptance criteria with reduced use of operator actions). Applicants may identify either safety-related or non-safety-related features or capabilities to satisfy the AIA rule. There is no requirement that the features or capabilities identified solely for complying with the AIA rule be classified as safety-related. The design features relied upon to satisfy the AIA rule may be structures or features: (1) whose sole purpose is to address the requirements of the AIA rule, or (2) designed to have a dual purpose of addressing the requirements of the AIA rule, as well as other NRC requirements (safety, security, etc).
