They’re gonna flood the drywell?

That’s what I get from this TEPCO proposal.  Correct me if I’m wrong.

Since it is unusual to flood the primary containment vessel (dry/well)…

Er…yes, that’s pretty unusual.  As in, “never been done before, to my knowledge”.  That’s a lot of water.  But they seem confident the added stress won’t be problematic.  And if I’m reading it right, they expect it to decrease the amount of rad material being spread from containment.

The only adverse side effect I see is that they might get overflow into a trench.  If that overflows it goes to the turbine building.  But they’ll be pumping out from the trench into the Waste Treatment Facility.  

Wow.  Sure hope they cyphered it twice, as Jethro would say.

I've accepted that all of you are socially superior to me. But no pretending that any of you are rational.

    I’ve always thought that the drywell should be designed for flooding in emergency cases. In fact, isn’t the drywell on the ESBWR designed for just such an eventuality (complete with a water reservoir for this, as well as an associated isolation condenser for cooling)?

    I was right, the ESBWR does: http://www.nuclear.gov/np2010/pdfs/esbwrOverview.pdf.

    In fact, in regards to accidents like Fukushima, it’s literally everything the Dai-ichi reactors aren’t, safety wise.
