Dear Mr. Saverot,

Holtec International is pleased to submit License Amendment Request (LAR) 9375-1 proposing certain changes to HI-STAR ATB 1T Certificate of Compliance (CoC) Number 9375 Revision 0 and its supporting Safety Analysis Report (SAR), Holtec Report HI-2146312 Revision 3. This LAR proposes one primary enhancement; specifically, the option to utilize HSLA-100 steel for the HI-STAR ATB 1T containment boundary (i.e., baseplate, walls, & closure lid) in addition to the previously permitted SA-517 or A514 materials. The safety analysis has been revised accordingly.

Considering the limited scope of this amendment and the importance of minimizing disruption to fabrication, we kindly request an expedited review and notify you of a need date of May 31, 2022 for the CoC.

The summary of proposed changes (SOPC) reiterating the proposed enhancement, including the reasons and justifications for the enhancement, is provided in Enclosure 1 to facilitate the Staffs review. contains Holtecs proposed changes to the Certificate of Compliance (CoC) for the Staffs convenience.

Proprietary and non-proprietary versions of the SAR are submitted herewith as Enclosures 3 and 4, respectively.
