RE: "Redundant drop protection features" at SONGS

Dear Mr. Langley:

Thank you for the question. On March 25, 2019, the NRC cited Southern California Edison with a Severity Level II Violation, accompanied by a $116,000 civil penalty, precisely because the company failed to ensure that redundant load drop protection features were available to prevent uncontrolled lowering of the load during multi-purpose canister transfer operations during the August 3, 2018 incident at San Onofre. Specifically, both of the two 100% redundant loading slings were disabled when a loaded used fuel canister became lodged on a shield ring inside the ISFSI vault. Please see the Notice of Violation attached to my letter to Mr. Doug Bauder at:

https://www.nrc.gov/docs/ML1908/ML19080A208.pdf Edison has implemented numerous corrective measures expressly designed to ensure that the August 3 incident is not repeated. The NRC staff has conducted extensive inspections of these corrective actions and continues to provide active on-site oversight of Edisons fuel transfer operations.

I have also forwarded your question to our technical and enforcement staff here in the regional office for their awareness.

[External_Sender] "Redundant drop protection features" at SONGS

Dear Mr. Morris,

I was just browsing through NRC Form 651 for SONGS ISFSI dated Certificate # 1040, Certificate of Compliance For Spent Fuel Storage Casks, Supplemental Sheet, CoC 1040 Appendix A Tech Spec, Item 5.2.c.3, and happened to notice that in regards to the Holtec MPC downloading process, "The lifting equipment shall have redundant drop protection features which prevent uncontrolled lowering of the load." (see Item 5.2.c.3 highlighted below).

Has Holtec or Edsion provided redundant drop protection during the downloading process? I haven't seen any mention of it in the news reports, press releases, or NRC documents. Was this detail overlooked?

Thank you so much.
