I try to give a slightly simplified account. It should be understandable to an engineer but the technicalities might be difficult for, say, a lawyer. One or more steam explosions are believed to have occurred during the Chernobyl nuclear accident. In this context a steam explosion can occur...

Thanks for your reply. I'm not sure whether CH is strictly required either. But I am certain in my mind that clarifies the issue. I'm also not sure about the argument about defining these cardinal numbers. If GCH is true - OK we cannot know that - let's us suppose it is true, then we consider...

Thanks, good to be here :smile:

Hello, I just joined. Worked a long time in (civil) nuclear, in connection with the safety organisations. I'm retired from paid employment but I learned some time ago that scientists don't stop working simply because they're retired, they just no longer get paid for it. Long time interested in...
