DESCRIPTION, JUSTIFICATION, AND EVALUATION OF AMENDMENT 1 8 CHANGES
INTRODUCTION
The scope of Amendment 18 to the Standardized NUHOMS Certificate of Compliance (CoC)
No. 1004 includes the changes described below.
Change No. 1 :
Provide for a 24PTH improved basket design using staggered plates similar to EOS -37PTH to simplify construction, reduce weight and improve fabricability. In CoC Appendix B Technical Specifications (TS), Table 1-1l, PWR Fuel Specification for the Fuel to be Stored in the NUHOMS - 24PTH DSC weight limit was increased from 1682 lbs to 171 5 lbs for fuel assembly plus CC based on the lighter T ype 3 basket. In addition, the total weight of the FFC and all its contents is deleted. For consistency with the two other DSCs that contain a similar total weight of the FFC plus all its contents statement, this statement is also deleted from Table 1-1e for the 32PT DSC and from Table 1-1t for the 61BTH DSC. CoC Appendix A, Inspections, Tests and Evaluations (ITE), has a new section added to address the high strength low alloy steel used in the new T ype 3 basket design for the 24PTH DSC. In addition, transfer cask does rate values were updated and simplified for the 24PTH DSC.
The CoC Appendix A (ITE), Appendix B TS, Appendix C ASME Code Alternatives and Updated Final Safety Analysis (UFSAR) have been revised accordingly, as described further in this enclosure. The CoC, appendices and UFSAR were revised to differentiate 24PTH Type 3 basket requirements from the existing 24PTH Type 1 and Type 2 basket requirements as necessary.
Lastly, the CoC 1004 renewal impact evaluation in E nclosure 9, with the main focus on the new Type 3 basket SSC changes, uses the latest Interim Staff Guidance on fuel retrievability as documented in ISG-2 Revision 2. As a result, Chapters 12 and P.1 have been updated to reflect ISG-2 Revision 2.
Change No. 2 :
Deletion of Appendix A ITE requirement for initial HSM delta T measurement with a loaded DSC.
Change No. 3 :
Clarifies Appendix B TS Section 4.3.2 language related to transfer casks with liquid neutron shields regarding the OS197L TC, which is significantly different than other TC models.
Change No. 4 :
Updated Appendix C ASME Code Alternatives Table C-12 to add code alternative NG-4231.1 as approved on February 3, 2022, ML22025A169
Page 1 of 8 Enclosure 2 to E-60447
Change No. 5 :
Change Appendix B TS Section 4.3.2, first paragraph, by removing a reference to 10 CFR Part 20 to clarify language indicating that the site specific evaluation in accordance with 10 CFR 72.212 is to demonstrate compliance with 10 CFR 72.104.
Change No. 6 :
Clarify TC/DSC annulus draining language in Appendix B TS Section 4.3.2 within the last paragraph.
Change No. 7 :
Clarify in Appendix B TS LCO 3.1.3 that there is no transfer time limit associated with the 24PTH-S-LC DSC, consistent with existing UFSAR analysis.
Change No. 8 :
Editorially correct CoC name/address information by adding missing space between 7160 and Riverwood Drive.
Change No. 9:
Incorporate administrative controls during short duration independent spent fuel storage installation (ISFSI) handling operations that are unanalyzed for tornado hazards in accordance with the guidance contained in NRC EGM 22-001, "Enforcement Discretion for Noncompliance of Tornado Hazards Protection Requirements at Independent Spent Fuel Storage Installations".
These changes are in UFSAR Chapter 3, the operational portions of Chapters 5, K.8, M.8, P.8, T.8, U.8, Y.8, and Z.8 and in Chapter 12.

Changes to the Standardized NUHOMS CoC 1004 UFSAR
Enclosure 7 (Proprietary version) and Enclosure 8 (Public version) provide proposed Amendment 18 changed pages for the Standardized NUHOMS UFSAR. Amendment 18 proposed UFSAR changes are tracked by italicized text and revision bars.
The following paragraphs discuss the UFSAR areas proposed for change, based on the changes described above. Editorial changes to correct spelling, grammar, etc. are also made to the changed UFSAR pages where appropriate.
In support of Change 1, changes are made to UFSAR Chapters 1, References; 12, Aging Management; Appendix P.1, General Discussion; P.2, Principal Design Criteria; P.3, Structural Evaluation; P.4, Thermal Evaluation; P.5, Shielding Evaluation; P.6, Criticality Evaluation; P.8, Operating Systems; P.9, Acceptance Tests and Maintenance Program; P.10, Radiation Protection and P.11, Accident Analyses.
In support of Change 2, a change was made to UFSAR Chapter 10, Operating Controls and Limits, to delete the ITE Bases section for ITE 4.4.
Changes 3 through 8 do not require UFSAR changes.

In support of Change 9, changes are made to UFSAR Section 3.2.1, Tornado Wind Loadings; operating procedures associated with DSC insertion or retrieval at the ISFSI in Chapters 5; Appendices K.8, M.8, P.8, T.8, U.8, Y.8, Z.8, and UFSAR Section 12.3.
JUSTIFICATION OF THE NEED FOR THESE CHANGES
Change 1 provides for a 24PTH improved basket design using staggered plates similar to EOS-37PTH to simplify construction, reduce weight and improve fabricability. In conjunction with the improved basket design, the weight limit was increased from 1682 lbs to 1715 lbs for Maximum Assembly plus CC Weight as a result of the weight reduction associated with the new EOS based staggered plate Type 3 basket design. In order to provide a consistent and appropriate level of detail related to fuel weights, the total weight of FFC plus all its contents requirement is deleted from Table 1-1l. For completeness, total weight requirement is also deleted from Tables 1-1e and 1-1t as well. The resulting level of detail is consistent with maximum assembly weight requirements contained in other CoC TS such as CoC 1029 and CoC 1042. Lastly, new Section 2.4 was added to Appendix A ITE to provide a discussion on the high strength low alloy steel that will be used in the new basket design. In addition, transfer cask do se rate values were updated and simplified for the 24PTH DSC. The CoC, Appendix A (ITE), Appendix B Technical Specifications (TS), Appendix C ASME Code Alternatives and Updated Final Safety Analysis (UFSAR) have been revised accordingly, as well, to differentiate 24PTH Type 3 basket requirements from the existing 24PTH basket requirements as necessary.
Justification for Removal of the Weight of the Failed Fuel Can (FFC) Plus All Its Contents
The weight of the FFC plus all its contents requirement is removed from the TS, but is retained without any changes within the UFSAR. Eliminating the weight of the FFC plus it contents does not modify the system behavior beyond the allowable bounds since:
- 1. The total weight of the FFC is mostly driven by the fuel assembly weight, which is already specified within the Technical Specifications.
- 2. The weight limit of the fuel assembly also includes the weight of the non-fuel assembly hardware. It is extremely unlikely that all of the fuel assemblies within a DSC are loaded to the maximum limit, which provides additional margin to the total weight limit.
- 3. The total weight requirement remains within the UFSAR to convey the design requirements and to ensure that any modifications to the FFC remain within the applicable bounds of the UFSAR evaluation.
- 4. There are only a few locations within each DSC wherein failed fuel assemblies are stored. If the weight of the FFC exceeds the maximum specified within the UFSAR, it is evaluated using the design change and 10 CFR 72.48 process. This will ensure that all design criteria including stress allowable limits and 10CFR 72.48 requirements are satisfied.
It should also be noted that removing the FFC weight limitation from the Technical Specification is consistent with more recent approvals such as the 32PTH1 DSC in the same CoC, 32PTH2 in Amendment 3 to CoC 1029 and EOS-37PTH in Amendment 1 to CoC 1042.

Change 2 removes CoC 1004 Appendix A ITE Section 4.4, HSM Maximum Air Temperature with a Loaded DSC. The purpose of this measurement was to ensure that the system is performing as designed by comparing the measured thermal performance of the cask against that predicted by the UFSAR thermal analysis for the same heat load. Operating experience from loading over 800 DSCs over more than two decades has resulted in no known delta T temperature issues and demonstrates that this requirement realistically no longer appears to be necessary and newer systems such as the CoC 1042 TS do not require this one time measurement after initial DSC loading.
Change 3 clarifies Appendix B TS Section 4.3.2 language related to transfer cask liquid neutron shields through formatting to more clearly indicate what applies to the OS197L TC.
Change 4 updates the Appendix C ASME Code Alternatives Table C-12 to add recently approved code alternative NG-4231.1. NRC approved this code alternative on February 3, 2022. ML22025A169
Change 5 improves the clarity of the Radiation Protection Program discussion by revising text in first paragraph to reflect that the evaluation pursuant to 72.212 is to confirm the limits of 72.104 for the actual site conditions.
Change 6 clarifies draining requirements language in the TS to indicate that the neutron shield level should be monitored when draining the TC/DSC annulus as those two drain locations are close to each other, but the NS level does not need to be monitored when draining the DSC cavity since the DSC cavity drain is on the opposite end of the DSC from the annulus and neutron shield drains.
Change 7 improves the clarity of the CoC 1004 Appendix B TS and is based on the existing thermal performance of the 24PTH-S-LC DSC during transfer operations in the Standardized TC. As noted in UFSAR Section P.4.6.5.2, the thermal evaluation of 24PTH-S-LC DSC with a heat load of 24 kW within the Standardized TC is performed for the following ambient conditions:
- Maximum normal ambient temperature of 100 °F with insolation, and
- Minimum normal ambient temperature of 0 °F without insolation
The results of these analyses are reported in UFSAR Table P.4-14 as results for HLZC 5 and in UFSAR Table P.4-17. As shown in the UFSAR Table P.4-14, there are no time limits specified for HLZC 5 unlike the columns for HLZC 1 and 4 which demonstrates that there are no time limits required.
Change 8 corrects a formatting issue with the CoC address information.
Change 9 incorporates administrative controls during short duration ISFSI handling operations that are unanalyzed for tornado hazards in accordance with the guidance contained in EGM 22 -
001. These changes are in UFSAR Chapter 3, the operational portions of Chapters 5, K.8, M.8, P.8, T.8, U.8, Y.8, Z.8, and Chapter 12 and provide a defense-in-depth approach that precludes ISFSI handling operations during periods of adverse weather involving tornado hazards, or when adverse weather involving tornado hazards is predicted, and contains compensatory measures to place important to safety SSCs in an analyzed condition, as necessary.
