the probability of a cask drop would occur if these heavy load handing procedures are not followed.

A Significant reduction in No the margin of safety for ISFSI or cask operation?

Evaluation Summary Based on this evaluation these Heavy Load Requirements should be moved to Section 4 of Appendixes B, D, and B-100U - Administrative Controls. Note that this administrative control is applicable to heavy load lifting procedures at the ISFSI. Lifts within the Reactor Building are governed by existing 10 CFR Part 50 license requirements.

However, Appendix B-100U is not being updated at this time. So, to avoid complicating the relationships between the CoC main body and the Appendixes, these requirements will remain in the CoC main body for now.

However, Appendix B-100U is not being updated at this time. So, to avoid complicating the relationships between the CoC main body and the Appendixes, these requirements will remain in the CoC main body for now.
