Re: I meant (none / 0)

Yeah, units are the bugbear. But I found the observation of the likelihood of putting very much water in from a moving helicopter at 90 metres up sounded accurate (though may be just truthy).

Fighting forest fires with planes and choppers is not an exact science, at the best of times. But at least they can get in lower than 90m.

Re: I meant (none / 0)

I think the more important observation is that even with a perfect hit you'd be adding 7.5 tonnes of water which would raise the water level by only 15 cm when the fuel assemblies are over 4m tall.

So dropping water from helicopters is just useless.

Re: I meant (none / 0)

I'd written it off as theatre.

I'm not sure for whose benefit.

And don't they have fireboats?

The range and flow of a fireboat must be an order of magnitude or two higher than a truck, surely?

Fireboats (none / 0)

Of course they do

Re: Fireboats (none / 1)

Addledum: I found the location of the above photo. I estimate the length of the longest water spray at about 130-140 m.

Re: I meant (none / 0)

This may not be obvious from tele photos, but if you check on Google maps, any point a ship can stop at is at least 200 m away even from the center of No. 4 (to the south where the cooling water exits), and the more suitable location is 350-400 m away (east of the reservoir).

Re: I meant (none / 0)

And 250 m even if you get a ship on the reservoir.

Re: I meant (none / 0)

and it might be that theres no access to number 4 from the seaward side. That looks to be where the walls are still standing.

You can't provide some protection from storm surges and tsunamis and remain accessible to waterships.

Re: Current Google Earth view: (none / 1)

Assuming the breakwater is a temporary obstacle that could be removed, and there's no spent fuel in that pool - if that even makes a difference at this point - I make that a distance of around 200m. Which doesn't sound totally impractical.

There's also the advantage of at least some cover from the turbine buildings.

Re: Current Google Earth view: (none / 1)

250 m. Plus you need to calculate with more due to the height. I looked around and found no fireboat range above 400 feet.
