This amendment to the CoC for the Standardized NUHOMS System includes the following changes:

Change No. 2:

Deletion of Appendix A inspections, tests, and evaluations requirement for initial horizontal storage module (HSM) delta temperature measurement with a loaded dry shielded canister (DSC).

Change No. 3:

Clarifies Appendix B technical specification (TS) Section 4.3.2 language related to transfer casks with liquid neutron shields regarding the OS197L transfer cask (TC),

which is significantly different than other TC models.

Change No. 4:

Updated Appendix C American Society of Mechanical Engineers Code Alternatives Table C-12 to add code alternative NG-4231.1 November 8, 2023

P. Narayanan Change No. 7:
