If the safety margin is 10mm-19mm and the crack is 2.9mm wide, I'd say the risk is non-existent.

- oliveshell 7y agoThis may well be the case during normal operation. It seems the worry, however, is that seismic activity etc. could lead to a steam explosion and release of radioactive gases if the plant failed to shut down. (I’m not a nuclear engineer and the article doesn’t make the assessed risks 100% clear, though.)
- rishabhsagar 7y agoI don’t have domain knowledge, so to me intuitively it feels like the risk of this crack quickly widening is real. Experts also seem to have called out risks due to factors such as quakes, steam escape etc.
- OnlyOneCannolo 7y agoThat's not risk. That's likelihood. The article admits that the likelihood is low, but the severity could be high. Risk is a combination of severity and likelihood. The nuclear industry has an entire discipline (PRA) dedicated specifically to risk assessment [1].
