Evaluation Summary Delete from CoC. The intent of this item is to limit possible oxidation of the fuel. It is mentioned elsewhere in the CoC (see LCO 3.1.1) that the dry MPC will be helium filled. Also, procedures in the FSAR already contain cautions that Inert gas must be used any time the fuel is not covered with water to prevent oxidation of the fuel cladding. The fuel cladding is not to be exposed to air at any time during loading operations. This caution applies to all sites and 10 CFR 72.150 requires that documented procedures be followed. Therefore, this item does not serve any safety purpose in the CoC and may be removed. | |||

Fuel assembly weight is a characteristic that would also not meet the Criteria A1 and A2 above. However, other CoC reorganization efforts have resulted in this characteristic being retained in the final approved CoC.

A Significant reduction in No the margin of safety for ISFSI or cask operation?
Evaluation Summary Delete from CoC. The intent of this item is to limit possible oxidation of the fuel. It is mentioned elsewhere in the CoC (see LCO 3.1.1) that the dry MPC will be helium filled. Also, procedures in the FSAR already contain cautions that Inert gas must be used any time the fuel is not covered with water to prevent oxidation of the fuel cladding. The fuel cladding is not to be exposed to air at any time during loading operations. This caution applies to all sites and 10 CFR 72.150 requires that documented procedures be followed. Therefore, this item does not serve any safety purpose in the CoC and may be removed.

Requirement Appendix D Section 3.9: Environmental Temperature Requirements
TRANSPORT OPERATIONS involving any version of the HI-TRAC transfer cask can be carried out if the reference ambient temperature (three day average around the cask) is ABOVE 0° F and below the Threshold Temperature of 110 deg. F ambient temperature, applicable during HI-TRAC MS transfer operations inside the 10 CFR Part 50 or 10 CFR Part 52 structural boundary and 90 deg. F outside of it.
The determination of the Threshold Temperature compliance shall be made based on the best available thermal data for the site.
If the reference ambient temperature exceeds the corresponding Threshold Temperature then a site specific analysis shall be performed using the actual heat load and reference ambient temperature equal to the three day average to ensure that the steady state peak fuel cladding temperature will remain below the ISG-11 Rev 3 limits. If the peak fuel cladding temperature exceeds ISG-11 Rev 3 limits, then the operation of a Supplemental Cooling System (SCS) in accordance with LCO 3.1.4 is mandatory.
