[Various] Japan Nuclear Emergency - Continuous Coverage of Damage and Radiation Risks - Page 164

What I cant understand is why they didn't build the reactors underground then use the whole ocean as a gravity pool to flood the reactors in case of melt down failure worst case scenario conditions?

They had access to the biggest gravity pool backup coolant system and totally decided not to use it.. they could have built steps into it to prevent back flow out in to the ocean too..

I'd have thought that would be pretty costly to build them underground, especially back in the 70's. Easy to say why didn't they do this with hindsight.

Also I'd have thought having the whole reactor underground when its an earthquake wouldn't do it much good.

details.. details.. personally I don't think any country should be sparing expenses while building nuclear reactors.

the floating nuclear reactors/ power plants on ships ideas are starting to make more since now..

Range I see 0.16 - 0.23 measurement: μSv/h (micro sievert/hour)
(I read that up to 0.27 is fine - 1.8 is max ok)

I sort of had a feeling yesterday this was going to happen, now not to take a poll but would you prefer off shore or on shore winds....either way we are looking at red sky's at night...if the jet stream changes like it normally does this time of year then it's more probable any radioactivity will stay north up in Canada. Before I get flamed...no I am not a weatherman, and it's a sad situation no matter which way the weather systems move clouds of radiation.

Try reloading. Works here on my end. Currently hovering between 0.12-0.15 in the counter.

A roundup of that Kyodo news on the no.4 reactor:

Radiation levels at the reactor have become too high for normal work in the control room. Workers cannot stay in the room long and so are going in and out alongside monitoring from a different room.
