RE: [cdn-nucl-l] NRU reactor: Never a real nuclear danger

Hey Jaro,

Prob'ly because that dried-out core is rolling along the bottom of the Ottawa River because that same earthquake caused the Swisha dam to collapse. Rolling along, that is, until it gets to Oiseau Rock where the water is around 290' (I'm sorry, 88.4 m) deep. It'll then stay there because the bottom suddenly rises as you go downstream....

Cheers,

Andy

John Waddington . Never a real nuclear danger

<SNIP>

And what would happen if, despite all these studies, the cooling systems all failed, along with everything else? AECL is required to analyze this event as part of the safety case that it must submit to the CNSC before it can get a licence to operate. The analysis predicts that, in the case where every back-up cooling system fails, the steel pipes fail, the confinement building fails, and the NRU operators do nothing at all to remediate any failures, the maximum dose that might be received by the most exposed member of the public would be 2.4 millisieverts (mSv). <SNIP>

Thanks Jerry,

Would anyone happen to know how a dried-out core full of very hot fuel manages to emit so little radiation ? ...thnx.
