The Holtec nuclear waste storage canisters at San Onofre are lemons and must be replaced with thick-wall casks.
The Nuclear Regulatory Commission (NRC) admits in their November 28, 2018 NRC Inspection Report and Notice of Violation, ML18332A357 (page 8 and 9) every Holtec canister downloaded into the storage holes is damaged due to inadequate clearance between the canister and the divider shell in the storage hole (vault). The NRC states canister walls are already “worn”. This results in cracks. Once cracks start, they continue to grow through the wall.
The NRC stated Southern California Edison (and Holtec) knew about this since January 2018, but continued to load 29 canisters anyway. Edison’s August 24, 2018 press release states they plan to finish loading mid 2019.
The NRC states Edison must stop loading canisters until this issue is resolved. However, there is no method to inspect or repair cracking canisters and the NRC knows this.
Instead, the NRC should admit the Holtec system is a lemon — a significant defective engineering design — and revoke both San Onofre and Holtec dry storage system licenses.
The NRC should require all San Onofre thin-wall canisters be replaced with thick-wall transportable storage casks. These are the only proven dry storage systems that can be inspected, maintained, repaired and monitored in a manner to […]
