Dear Ms. Garcia Santos:

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.

Note that any previous changes associated with Amendment 6 remain tracked in Attachments 2 &

3, while only the latest changes are highlighted for clarity. contains Appendix A of CoC 72-1032 with changes specifically resulting from the latest revisions of the supplemental responses.
