CFR Part: 
CFR Title: 

Content:
esigns for fuel storage provide assurance that spacing is adequate to prevent not only criticality during earthquakes or other natural phenomena, but also flooding of dry fresh fuel storage racks with potential moderators. The configuration of new fuel storage must also prevent the insertion of potential moderators into existing spaces. ANSI/ANS 57.1 and ANSI/ANS 57.3 provide guidance acceptable to the staff for meeting the requirements associated with fresh fuel storage and handling. The configuration of spent fuel storage must also prevent the insertion of a fuel assembly anywhere other than in a design location. ANSI/ANS 57.1, ANSI/ANS 57.2, and Regulatory Guide 1.13 provide guidance acceptable to the staff for meeting the requirements associated with spent fuel storage and handling. Meeting the requirements of GDC 62 provides assurance that criticality will be prevented in the fuel storage facilities. 2. Compliance with 10 CFR 50.68 requires that the licensee either maintain monitoring systems capable of detecting a criticality accident as described in 10 CFR 70.24, thereby reducing the consequences of a criticality accident, or comply with the requirements specified in 10 CFR 50.68(b), thereby reducing the likelihood that a criticality accident will occur. III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. 9.1.1-5 Revision 3 - March 2007 For applications filed under 10 CFR Part 50, the procedures below are used during the construction permit application review to confirm that the design criteria and bases and the preliminary design meet the acceptance criteria in
