i dont believe those radiation levels AT ALL...
they reported 400 MILI sieverts yesterday, and today its back to MICRO sieverts? yet they are very worried about radiation, a lot more than yesterday, and aborted the helicopter mission and police truck mission because of high radiation...
LIVE: another earthquake hits japan, around 3-4
luckily no tsunami...
but all trains have stopped
could be felt in tokyo
update: it was a 5.8 quake, but the effects in cities closest to it were around 4.x
3-4 isn't enough for tsunami.
As for the news, i'm reading Kyodo's.
One thing i really think it's not very effective, is the dropping of water, by helicopters, at that height ... We see the wind spreading the water all over.... meh ...
They can't get any closer due to radiation levels apparently :(Quote:

nhk reports: when asked why they took so extraordinary steps to refill the storage pools, they said "today was the last chance"
a very controversial quote which scared the public... it sounds as if something big would have happened if they could not have refilled the pool in reactor4 today
Maybe there are damaging to the containment vessels ... and they can't get another explosion... :x jeez...
Fukushima power plant was a gen 2 correct? Are the gen 3 any safer?
as far as i know, gen3 cool themselves automatically based on convection, hot water moving up by itself, and cold water moving down. they dont require any intervention and electricity, they are supposedly able to shut down automatically without any intervention and external power whatsoever... then again, this cooling system COULD get damaged by strong earthquakes or other disasters as well, so... even gen3 reactors wont be 100% safe...Quote:

These smaller quakes are the tectonic plates, re-positioning ... it will take some time ... :x
As for the Gen 3 plants ... well .. i think this accident will be a starting point to rethink nuclear power plants... unfortunately...
I don't believe that nuclear power will go away, but there will be further R&D on safety measures for sure ... and maybe... they will try to not install a power plant in the coast line?! ... that would be a good options imo ...
No one talked abut the vulcano that erupted just after the quake ... it was an isolated eruption ?
I don't know what the news is saying over there but in the US the helicopter mission was stopped before the 1st 40 minute shift was completed. They may have "dropped" 30 tons of water but if you saw the video most of the water was scatterred by the wind. The water cannons were pulled back because the radiation was too high.

Ahh the reactors are getting worse :/ worst thing if its a domino effect and ends up not being able to go near it at all :/
nothing about the volcano, don't think it was serious and doubt it affected a lot of peopleQuote:

I find it astonishing that there are 55 reactors in Japan, mainly due to there lack of resources such as gas and oil and there feverish drive for dependency after the 1970 oil crisis...that's 55 reactors!
I'm confused why nothing else is happening today... they plan to spray more water onto reactor 3 and 4 and install new pumps and power lines. Well... so what are they waiting for? It almost sounds like they are going home now and take a rest and will be back tomorrow? 0_o
I know that's not the case, but... its weird...
Isn't it 55 plants?Quote:

There are much safer designs in existence than boiling water. I'm a big fan of molten salt reactors. The fuel is intermixed with the coolant and in the case of an "oh :banana::banana::banana::banana:" scenario the molten salt core is dumped into passively cooled storage tanks. Since the core is already molten it is designed to be contained. If all cooling power is lost the core automatically dumps itself. Lastly, the core operates at very low pressure but very high temperature and with no water present there is no chance at a pressure explosion.Quote:

It might be that this is their last attempt of controling the plants and cooling them down and if this fails they will have start to encapsulate the reactors instead.Quote:

It touches upon this subject.
Reactors, not plants.Quote:

As long as my post doesn't cause another uproar of sorts.
What's the life expectancy of the radiation around the area?
25 thousand years ???, or under a 100 ?
Is there a list of sites to gather radiation info from in realtime so I can make a kml for that in google earth... (globaly not just japan) ?
And what do you guys honestly think the "worse case" is ? (not to jump the gun or anything...)
1/3 of japan is no longer safe to live in ?
Or the whole country ?
Consider the short half life of the radioactive gas, wind direction and other weather effects and variable amount of steam from the reactors. I think it could be possible.Quote:

Edit:
Got $0 in paypal too, what to do what to do's... :\
Mmm...
Is there some sort of volunteer program ?, I'de hate to leave my kitty cat but...
It's a lost cause .. and they know it ,all this cooling idea is bogusQuote:

New video is up of the Fukushima Daiichi plant. Taken by a TEPCO employee. The situation looks bad.

Most of the stuff inside the reactor is uranium (U-235 and U-238) wich is not really dangerous by itself as it has a half-time measured in hundreds of millions of years; then there's Plutonium, isotope Pu-239 being used in small percentage as a fuel in reactor 3 but also being a byproduct of reaction in all the other reactors, and with a half-time of 24000 years is a bit more active. Large atomic mass and relatively high melting and boiling points means there is not a big danger of chemical contamination with them as well.Quote:

Iodine 131 is the most dangerous on the short term (half-time 8 days) as it can be transported large distances by winds (low boiling point, 184 C, it can exit the reactor as a gas), but it decays rapidly and after a month the danger is close to zero. Caesium 137, although boils much harder (670 C) is very chemically active and the salts formed are soluble in water, also half-time is 30 years, so is this is spilled into enviroment it will make it uninhabitable for a long time.
jeee :( how is the cooling supposed to work ?!? i see that the pipe system is a mess ... :x
Wish it had subtitles, but your right, the images alone look devastating. I think they should start disclosing more information.Quote:
