edures of handling operations, if the redundancy and diversity needed to protect against malfunctions or failures are provided, and if the design conforms to the relevant requirements of the following regulations: 1. General Design Criterion 2 (GDC 2), as related to the ability of structures, equipment, 13 and mechanisms to withstand the effects of earthquakes. Acceptance is based on meeting 9.1.4-5 DRAFT Rev. 3 - April 1996 Regulatory Guide 1.29, positions C.1 and C.2, and positions C.1 and C.6 of Regulatory Guide 1.13. 2. General Design Criterion 5 (GDC 5), as related to the capability of shared equipment 14 and components important to safety. 3. General Design Criterion 61 (GDC 61), as related to a radioactivity release as a result 15 of fuel damage, and the avoidance of excessive personnel radiation exposure. Acceptance, in part, is based on the guidelines of position C.3 of Regulatory Guide 1.13 and ANS 57.1/ANSI-N208 (Reference 7).16 4. General Design Criterion 62 (GDC 62), as it relates to criticality accidents. Acceptance 17 is based on part on meeting position C.3 of Regulatory Guide 1.13 and ANS 57.1/ANSI-N208. 5. In meeting Criteria 61 and 62 specific criteria regarding the maximum kinetic energy of any load lighter than a fuel assembly is identified in item 6, subsection III of this SRP section. Technical Rationale18 The technical rationale for application of these acceptance criteria to reviewing the LLHS is discussed in the following paragraphs:19 1. Compliance with GDC 2 requires that structures, systems, and components important to safety be designed to resist the effects of natural phenomena such as earthquakes. GDC 2 is applicable to SRP Section 9.1.4 because it specifies the natural phenomenon (i.e., earthquake) that must be considered in the design of the LLHS. If not considered, an earthquake could overload LLHS structures, systems, and components to the extent that it could cause an unsafe condition (e.g., a fuel assembly drop with the
