Has anyone mentioned the fact that Kyoto has been ****ing up for a while lying about **** in reports? I saw on the news the last time they had an incident that they claimed to have only lost a gallon of contaminated water but it was alot more than that.

what are you talking about?

It seems like filling a reactor containment with water would be much, much more difficult with a leak of any significant size. The figure I've heard is a "5%" breach (on wiki, referencing a spokesman). To me it doesn't really matter if the breach is 1% or 50%. It's breached, meaning that unless the breach is sealed god knows how, there will be significant radioactive release.

I think he meant TEPCO

stick dicks in me

i think they will evacuate tokyo like pripyat

worse than Chernobyl

doomsday millions will be dead by easter

list of things i haven't said in this thread

You got to separate 2 different things first. Radiation and a radiation source.
Radiation hits you and damages tissue/whatever. A radiation source emits radiation.

Radiation can be countered by creating distance and/or shielding. Containing the source depends on the form of the source. If the fuel rods melt you just contain it in concrete and some other substances. It isn't going to run away. Once cooled down you actually get a cool glass structure. This isn't dangerous by definition.
Dangerous is when some particles/objects turn into a source. In a fire for example ash could become a radioactive source. Ash flows with the wind. If it is going your way, you could swallow a source. There would be a radioactive source in your body emitting radiation 24/7. You can not run from that.

So the question is. What was breached, where and how? If it's the roof then it could get in the air through smoke/ash/steam/etc. (very dangerous, hard to contain) If it's in the floor then it could leak into the ground. (immediate action required, can still be contained) If the breach is on the other side of the structure then it could be nothing.
It's not like the whole building is filled with radioactive material.

when they say there are 2 holes (28ftx28ft) in the containment vessel that were blown open in the explosion...which 'russian doll' vessel is this?

Where did you get this 28ft number from?

It was in the building of #4 reactor which has been converted to a spent fuel pool. Like the other buildings that blew up.

At 6:14 a.m. on Tuesday, a blast occurred at the No. 4 reactor and created two square-shaped holes about 8 by 8 meters in the walls of the building that houses the reactor.

from the thing that jomo posted...they said two square holes measuring 8 meters x 8 meters.

didn't realize it was #4 - so not as dangerous as it would be if it was an active reactor i guess

huh? 2 of the 3 reactor buildings have blown up?

The containment vessel is undamaged in those two explosions but all that is left is the framework of the building.

This was the 1st reactor I think

yeah i guess what i'm confused about is what part of the reactor as the 8x8 meter holes in it....is it the outer building as pictured in your post...or is it deeper inside?

and if its deeper inside, better that it happened to a reactor storing spent fuel rods than one that is a production reactor....(or maybe not?)

I thought it was 3 of the 4 have had hydrogen explosions?

Yeah, but 4 isn't acting as a reactor, just a spent fuel pool.

The outer building. Here's the image I was trying to find Basically just the top blew off, the reactor itself was fine:

Mind that the outer building is actually multiple structures put together. I can remove walls and floors and still not reach the room of the reactor vessel.

yep and building #3 was a lot more damaged.

I thought the one explosion they were worried about damaged that ring (torus) on the bottom? When they lost pressure.

Reactor #1 and # 3: Hydrogen explosion, building damaged.

Reactor #2: Explosion heard near the suppression pool. Possible damage to containment vessel. They reported a pressure drop from 3 AU to 1 AU and a rise in radiation. (building damaged from explosion #3)

Building #4 (spent fuel pool, is a reactor but has been reconfigured) Explosion that damaged the building and fire possibly due to hydrogen from boiling pool or something else. Not a lot of info was certain on this.

TEPCO press release on the #4 reactor (earlier today)

At approximately 6:00am, a loud explosion was heard from within the
power station. Afterwards, it was confirmed that the 4th floor rooftop
area of the Unit 4 Nuclear Reactor Building had sustained damage.

After usage, fuel is stored in a pool designated for spent fuel.

Plant conditions as well as potential outside radiation effects are
currently under investigation.

TEPCO, along with other involved organizations, is doing its best to
contain the situation. Simultaneously, the surrounding environment is
being kept under constant surveillance.

Ok, where's the suppression pool? I thought the suppression pool was that ring.

Ok yeah.
Containment building - Wikipedia, the free encyclopedia
In a BWR, the containment strategy is a bit different. A BWR's containment consists of a drywell where the reactor and associated cooling equipment is located and a wetwell. The drywell is much smaller than a PWR containment and plays a larger role. During the theoretical leakage design basis accident the reactor coolant flashes to steam in the drywell, pressurizing it rapidly. Vent pipes or tubes from the drywell direct the steam below the water level maintained in the wetwell (also known as a torus or suppression pool), condensing the steam, limiting the pressure ultimately reached.

I heard on NHK last night that #4 doesn't have a containment building since it only had spent rods or something.

One thing is for sure, they need to come up with a better naming/numbering scheme for plants/reactors.

The outside "containment" shells. The ones that have huge holes and have blown up, dont do ****. They are there as a roof. Its the inside containment units anyone needs to worry about. So the fact that they are missing is kind of whatever.

From what I gather, the spent fuel pool (in reactor #4) is something like this:

That would be the only way that 'dropping water from helicopters' would make sense.

Would be nice if we got some real info on the reactors. "Damage to containment vessel" still makes you guess what was actually damaged. It's more complex than some room that's leaking.

**** man that's what the Chinese swimmers practice in.

Containment has already been breached.

Yes, I know the fire is out now.

Every page I've read in this thread I see Tappy spewing out doom and gloom. Get ****ed ******.

The fire in #4 was put out 2 hours after it started, iirc.

The type or radioactive material being released has a half life of miliseconds. Its the same thing that happend at 3 mile island. For the past 30 years they have been doing tests at and around 3 mile island and have found no detrimental effects.

Conclusion: You have no idea wtf you're talking about.

Posting verbatim reports from the IAEA is spreading doom and gloom?

:lol:

Boat! Get down off that house, you don't belong up there, you're a boat. Get back in the water.

Good thing they will be back to normal yesterday.

also, you think the people who own that building get to keep the boat?

not trying to be insensitive but I mean how the **** are they gonna get it off of there?

Crazy how water can push an entire house underneath a boat.

boats thinking they are cars over there
