eon3 | NRC: No technology to find cracks in Holtec thin nuclear waste canisters @eon3 | Uploaded October 2015 | Updated October 2024, 1 hour ago.
The California Coastal Commission has approved a Southern California Edison (SCE) radioactive waste storage plan for the shut down nuclear plant at San Onofre although the plan relies on technology that does not yet exist. At issue is the type of dry storage cask system that will be used to store the highly radioactive waste on site in an earthquake and tsunami zone and a corrosive seaside environment.
There are currently 50 canisters holding more radiation than was released at Chernobyl, with plans for 75 more holding even higher amounts. There is one canister holding Greater Than Class C (GTCC) waste and six more planned. GTCC remains extremely hazardous for more than 500 years http://1.usa.gov/1G6RXcS

NRC Director Mark Lombard, admits these canisters can crack. However, he says the ability to detect cracks or the depth of cracks is 'not a 'now thing'", yet he approves Holtec and other thin canisters for 20 years. Only promises of future solutions one of these days.
The robotic he refers to is just a tool to put through the air vents of the outer cask, so they can access the surface of the canister. There is no inspection technology in existence that currently works with that robotic and any technology solution will be limited.
When these canisters are manufactured, the NRC requires a fluid dye to be put inside the canister, so they can see where the cracks might be. However, once the canisters are filled with nuclear waste, that is impossible to do. So they have designed a product that cannot be inspected or maintained.
Holtec canister vendor, Dr. Singh says even if you find the cracks you cannot repair them without introducing another corrosion factor. And you would be attempting to do this in the face of millions of curies of radiation being released from even a microscopic crack.
Watch Dr. Singh: youtu.be/euaFZt0YPi4 Go to SanOnofreSafety.org for more details and to learn what you can do to ensure any nuclear waste is stored in thick casks (10" or more) that don't crack rather than 1/2" to 5/8" thin Holtec canisters
The NRC refuses to raise their storage standards to require thick dry casks that can be inspected and maintained. Edison has the ability select a thick cask, but they refuse.
