List of Approved Spent Fuel Storage Casks: TN Americas LLC, Standardized NUHOMS® System, Certificate of Compliance No. 1004, Renewed Amendment No. 15
Document Number: 2018-24256
Type: Proposed Rule
Date: 2018-11-07
Agency: Nuclear Regulatory Commission, Agencies and Commissions
The U.S. Nuclear Regulatory Commission (NRC) is proposing to amend its spent fuel storage regulations by revising the TN Americas LLC Standardized NUHOMS[supreg] Horizontal Modular Storage System (NUHOMS[supreg] System) listing within the ``List of approved spent fuel storage casks'' to include Renewed Amendment No. 15 to Certificate of Compliance No. 1004. Because this amendment is subsequent to the renewal of the TN Americas LLC Standardized NUHOMS[supreg] Certificate of Compliance 1004 system and, therefore, subject to the Aging Management Program requirements of the renewed certificate, it is referred to as ``Renewed Amendment No. 15.'' Renewed Amendment No. 15 would revise the Certificate of Compliance's technical specifications to: Unify and standardize fuel qualification tables; revise existing and add new heat load zoning configurations; increase the allowable maximum assembly average burnup; allow loading of damaged fuel assemblies under certain conditions; expand the definition of the poison rod assemblies to include rod cluster control assembly materials; allow other zirconium alloy cladding materials; add model OS197 as an authorized transfer cask; add the description for the solar shield in the updated final safety analysis report; and add flexibility to general licensees in verifying compliance regarding the storage pad location and the soil-structure interaction. Additionally, the rulemaking would make clarifications to rule text related to Certificate of Compliance No. 1004 by removing redundant language.
