Dear Mr. OMullane:

By letter dated October 2, 2019 [Agencywide Documents Access and Management System (ADAMS) Package Accession No. ML19282C357], and as supplemented on June 30, 2020 (ADAMS Package Accession No. ML20182A860), Holtec International (the applicant) requested to amend Certificate of Compliance (CoC) No. 1032, Model No. HI-STORM FW Storage System. The applicant proposes the following changes:

1) Adding an anchored configuration of the HI-STORM FW storage system.

2) Allowing non-single failure proof lifting equipment during handling of heavy loads processes (within the 10 CFR Part 72 jurisdictional boundary).

3) Revising LCO 3.1.2, SFSC Heat Removal System Operability, to allow an engineering evaluation to be performed in lieu of transferring the multi-purpose canister (MPC) into a transfer cask.

4) No longer require the annual submittal of a separate radioactive effluent report for the HI-STORM FW system.

5) For the MPC models MPC-37, -89, and -32ML, revise the following:

a. the allowable contents to clarify the requirements for fuel debris permitted for storage, and

b. the basket Design Features to clarify that the minimum cell inside dimension (ID) and minimum cell wall thickness are nominal dimensions.
