Discuss response to Structural RAI 3-3 Regarding HISTORM FW, Amendment 6 (Docket No. 72-1032), dated March 24, 2021.

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 [2]. 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 is pleased to submit its supplemented responses to the aforementioned RAIs in of this letter.

contains supplemental RAI-related changes to the HI-STORM FW FSAR. Note that all previous changes associated with Amendment 6 remain tracked in Attachment 2, while changes specifically resulting from the supplemented responses are highlighted for clarity. Attachment 3 contains Revision 1 of proprietary Holtec Licensing Drawing 11695 for the HI-STORM FW Version E Anchored Overpack. Attachment 4 contains Revision 3 of proprietary Holtec Report HI-2200647 which documents the numerical analyses for the accidental vertical drop of the loaded HI-STORM FW Version E spent fuel storage cask and loaded HI-TRAC VW spent fuel transfer cask, as well as the HI-STORM FW Version E anchored cask under the combined loading of the Design Basis Tornado and Design Basis Missile impact.

As Attachments 3 & 4 are considered proprietary, an affidavit requesting that this information be withheld from public disclosure in accordance with 10CFR2.390 is contained in Attachment 5.

If you have any questions please contact me at c.omullane@holtec.com or 856-912-1162.

Sincerely, Christopher OMullane Licensing Engineer, Holtec International
