Section ID: 9.1.1
CFR Part: 
CFR Title: 

Content:
: 1. Fuel assembly design to verify that appropriate fuel assembly data were used. 2. Fuel storage rack design to verify that appropriate fuel storage rack data were used. 3. Evaluation of performance effectiveness of the neutron absorbing materials in the fresh and spent fuel racks. 4. Computational methods and related data to verify that acceptable computational methods and data were used. 5. Computational method validation to verify that the validation study is thorough and uses benchmark critical experiments that are similar to the normal-conditions and abnormal- conditions models and to verify that the neutron distribution coefficient (K(eff)) bias and bias uncertainty values are conservatively determined. 6. Identification of normal conditions to verify that the scope of specified normal conditions is comprehensive. 7. Normal-conditions models to verify that normal conditions are modeled conservatively and that all modeling approximations and assumptions are appropriate. 8. Identification of abnormal conditions to verify that the scope of considered abnormal conditions is comprehensive. 9. Abnormal-conditions models to verify that abnormal conditions are modeled conservatively and that all modeling approximations and assumptions are appropriate. 10. Analysis of normal and credible abnormal conditions to verify that the analysis is complete and logically sound and that assumptions, limits, and controls are clearly stated. 11. Analysis conclusions to verify the applicant’s conclusions regarding maintaining subcriticality for all normal and credible abnormal conditions. 12. Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC). For design certification (DC) and combined license (COL) reviews, the staff reviews the applicant’s proposed ITAAC associated with the structures, systems, and components (SSCs) related to this SRP section in accordance with SRP Section 14.3, “Inspections, Tests, Analyses, and Acceptance Criteria.” The staff recognizes that
