SUPPLEMENTARY INFORMATION: On October 13, 2009 (74 FR 52387), the NRC 
published a direct final rule amending its regulations at 10 CFR 72.214 
to include Amendment No. 7 to CoC Number 1014. Amendment No. 7 modifies 
the CoC to add the HI-STORM 100U system to the HI-STORM 100 cask 
systems. The HI-STORM 100U system allows for the underground storage of 
dry spent nuclear fuel (SNF) by utilizing an underground vertical 
ventilated module (VVM) that can accept certain Holtec multipurpose 
canisters previously certified for storage of SNF in the aboveground 
HI-STORM system. The amendment also incorporates a mandatory radiation 
protection perimeter around the loaded VVMs. In addition, the amendment 
will reinstate the decay heat limits for damaged fuel and fuel debris 
in Appendix B, Technical Specification (TS) 2.4, for the aboveground 
system that had been inadvertently deleted from Amendment Nos. 5 and 6; 
incorporate separate TS Appendices A and B for the HI-STORM aboveground 
system, and TS Appendices A-100U and B-100U, for the HI-STORM 100U 
underground system; revise Appendix B, TS 3.4.5, to be consistent with 
the required system thermal boundary conditions, as submitted in the 
applicant's safety analysis report for a fire accident condition, and 
with Holtec's original (i.e., initial certificate application or 
Amendment 0) submittal and the NRC's original safety evaluation report; 
revise and add certain definitions in Appendix A, TS 1.1, to include 
the VVM; and incorporate minor editorial corrections in the TS for the 
aboveground system. In the direct final rule, NRC stated that if no 
significant adverse comments were received, the direct final rule would 
become final on December 28, 2009. The NRC did not receive any comments 
on the direct final rule. Therefore, this rule will become effective as 

    Dated at Rockville, Maryland, this 7th day of December 2009.

    For the Nuclear Regulatory Commission.
