Dear Ms. Garcia Santos:

By letters dated September 24, 2020 [1] and November 6, 2020 [2], the NRC staff sent staggered Requests for Additional Information (RAIs) needed to complete their detailed technical review of Amendment 6 of the HI-STORM FW Certificate of Compliance (CoC) 72-1032. Holtec provided responses to the RAIs by letter dated December 21, 2020 [3]. Subsequent to submittal of these responses, Holtec and the NRC staff participated in two telephone conference calls on March 8, 2021 [4] and March 24, 2021 [5], during which it was determined that clarification was warranted for Holtecs responses to Thermal RAIs 4-1 & 4-2, Materials RAI 4-1, and Structural RAIs 3-1, 3-2, & 3-3. Holtec provided supplemental responses to these RAIs by letter dated August 2, 2021

[6]. Following submittal of the supplemental responses, further discussion between Holtec and the NRC staff regarding Thermal RAIs 4-1 & 4-2 and Structural RAIs 3-1, 3-2, & 3-3 determined additional clarification was necessary.
