Thin-walled nuclear waste containers – not really very secure

Greg Phillips, Nuclear Fuel Cycle Watch 4 June   The biggest piece of BS that jumped out at me [in this pro nuclear article] is the bolded section:

“…Nuclear waste containers have been tested over the last 40 years by running them into concrete bunkers at 80 mph, being dropped onto huge steel spikes, burned in jet fuel fires at thousands of degrees, and sunk deep in water for weeks. These things are as strong as humans can make them.”

ONLY TRANSPORT CONTAINERS HAVE BEEN SUBJECTED TO THE ABOVE TESTS. THE THIN WELDED CONTAINERS PLACED INTO A PROTECTIVE OUTER SHELL OF CONCRETE. THE PRESSURISED THIN INNER CONTAINERS ARE VENTED TO OPEN AIR TO LET HEAT ESCAPE. ANY LEAK FROM A FAILED WELD WILL ESCAPE TO THE ENVIRONMENT.

Excuse the caps, but too many people have been fooled by such pro-nuclear propaganda. Pictured at top is a thin welded canister – a fully laden canister would not survive a drop of a few metres.

Those nuclear waste containers pictured above are like hermit crabs, a hard exterior shell with vulnerable internals. The thin welded canister is placed into the concrete outer shell, which has vents to keep the canister cool. So any weld failure, crack can lead to radioactive contamination into the atmosphere. If the vents of the outer shell get blocked, the temperature of the fuel will rise to 400C+. If the pressurised Helium leaks out the temperature will rise. https://www.facebook.com/groups/1021186047913052
