The U.S. Nuclear Regulatory Commission (NRC) is amending its spent fuel storage regulations by revising the Standardized NUHOMS[supreg] Horizontal Modular Storage System (NUHOMS[supreg] System) listing within the "List of approved spent fuel storage casks" to renew, for an additional 40-year period, Revision 1 of the initial certificate and Amendment Nos. 1 through 11, and 13, and Amendment No. 14 of Certificate of Compliance (CoC) No. 1004. These changes require, among other things, that all future amendments and revisions to this CoC include evaluations of the impacts to aging management activities (i.e., time-limited aging analyses and aging management programs (AMPs)) to ensure that they remain adequate for any changes to spent fuel storage cask systems, structures, and components (SSCs) within the scope of the renewal. Each general licensee using a NUHOMS[supreg] System at a reactor site must have a program to establish, implement, and maintain written procedures for each AMP described in the AREVA Inc. (AREVA) Updated Final Safety Analysis Report (UFSAR). In addition, the renewals reflect the change in the name of the CoC holder from AREVA to TN Americas LLC, and make several other changes as described in Section IV, "Discussion of Changes," in the SUPPLEMENTARY INFORMATION section of this document.
