vide assurance that components of the new and spent fuel storage facilities will generate radiation doses that comply with the ALARA standard. 7. 10 CFR 50.68 requires provisions either to monitor for criticality accidents pursuant to 10 CFR 70.24 or to follow its guidelines to ensure Keff will not increase beyond safe limits. 9.1.2-8 Revision 4 - March 2007 10 CFR 50.68 as to the dry storage of fuel ensures an adequate degree of subcriticality or adequate criticality monitors. The applicant may provide radioactivity monitors as specified in 10 CFR 70.24, administrative controls and/or design features to prevent flooding of the dry storage area, or analysis to show that Keff does not exceed 0.95 if the storage area is flooded with unborated water and that Keff does not exceed 0.98 if the storage area is filled with an optimum moderator (e.g., fire extinguishing foam), assuming fuel of the maximum reactivity. SRP Section 9.1.1 provides the guidance necessary for criticality evaluation in the new and spent fuel storage areas. 10 CFR 50.68 requirements ensure that criticality accidents will not endanger the safety of personnel. 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 to the SRP criteria provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. Upon request from the primary reviewer, the interfacing review branches provide input for the areas of review stated in Subsection I of this SRP section. The secondary review branch provides an input routinely for areas of review of this SRP section. The primary reviewer uses such input as required to complete this review procedure. 1. The SAR is reviewed to determine whether the
