9.1.1
ML070570006
Criticality Safety of Fresh and Spent Fuel Storage and Handling A) Use SRP Section "as-is" (minor comments)  
9.1.2
ML070550057
New and Spent Fuel Storage A) Use SRP Section "as-is" (minor comments) Amended to accommodate mPower™-specific single spent fuel pool shared by two units. Section III. Review Procedures Item 1. Change this to read: 1.The SAR is reviewed to determine whether the design bases and facility description section indicate the storage capacity of the design. The minimum storage capacity in the spent fuel storage pool should equal or exceed the amount of spent fuel from five years of operation at full power plus one full core discharge from each unit sharing the pool. Due to insufficient away-from-reactor storage capacity, the industry trend has been to use high-density storage racks. The reviewer evaluates high-density storage case by case. Low-density storage should be used, at a minimum, for the most recently discharged fuel to enhance the capability to cool it.
