Enclosure 5 to E-55201 Proposed Amendment 2, Revision 3 NUHOMS EOS System Updated Final Safety Analysis Report Changed Pages (Public Version)

NUHOMS EOS System Updated Final Safety Analysis Report Rev. TBD, TBD October 2019 Revision 3 72-1042 Amendment 2 Page A.4-36 Appendix A was added in Amendment 1.

Temperatures for LC 1e-S-full-O are also compared with the periodic model (LC 1e-S of Table A.4-14) in Table A.4-33a through Table A.4-33c. Table A.4-33a shows that the maximum fuel cladding temperature of the upper fuel for LC 1e-S-full-O increases compared to the periodic model, but is still lower than the maximum fuel cladding temperature of the lower fuel in the periodic model. The concrete temperatures is higher when compared with LC 1e-S, but is still lower than the design limit. Table A.4-33b shows that the lower compartment component maximum temperatures of LC 1e-S-full-O are all bounded by LC 1e-S but the upper compartment component maximum temperatures are higher. However, the average temperatures of all components in both upper and lower compartments for LC 1e-S-full-O are bounded by LC 1e-S, as shown in Table A.4-33c.

Internal Pressure As shown in Table A.4-33c, the average cavity gas temperatures determined for the medium EOS-37PTH DSCs in the updated full HSM-MX model with HLZC 7 under the normal storage condition are 9 °F and 28 °F lower than those from LC 1e-S for the upper and lower compartments, respectively. Therefore, the maximum internal pressures for LC 1e-S-full-O with HLZC 7 are bounded by those for the LC 1e-S in Section A.4.5. As discussed in Section A.4.5, the maximum internal pressures in Chapter 4, Table 4-45 is bounding for LC 1e-S with HLZC 7. Therefore, the maximum internal pressures in Chapter 4, Table 4-45 remain bounding for those of LC 1e-S-full-O for HLZC 7 for normal, off-normal, and accident conditions.

A.4.6.5 Temperature Calculations The maximum temperatures of fuel cladding and concrete of the HSM-MX loaded with the EOS-37PTH DSC with HLZC 11 are summarized in Table A.4-36. The maximum fuel cladding and concrete temperatures are 699 °F and 280 °F, within the temperature limits of 752 °F and 300 °F, respectively.

The maximum and average temperatures of key components of the HSM-MX loaded with the EOS-37PTH DSC for the storage conditions are summarized in Table A.4-37 and Table A.4-38, respectively. Average temperatures are calculated based on the volume average temperatures of the elements representing the whole component.
