## Abstract

The U.S. Nuclear Regulatory Commission (NRC) is amending its spent fuel storage regulations by revising the Holtec International HI- STORM 100 Multipurpose Canister Cask System listing within the "List of approved spent fuel storage casks" to include Amendment No. 14 to Certificate of Compliance No. 1014. Amendment No. 14 revises the technical specifications to add new heat loading patterns, reduce the minimum cooling time, allow use of a damaged fuel isolator for storing damaged fuel, and modify the description of vents in overpack. Amendment No. 14 also makes other administrative changes to the technical specifications. These revisions are discussed in more detail in the "Discussion of Changes" section of this document.
