SOMA, Japan – The second hydrogen explosion in three days rocked Japan's stricken Fukushima Dai-ichi nuclear plant Monday, sending a massive column of smoke into the air and wounding 6 workers.
The plant's operator said radiation levels at the reactor were still within legal limits.
The explosion at the plant's Unit 3, which authorities have been frantically trying to cool following a system failure in the wake of a massive earthquake and tsunami, triggered an order for hundreds of people to stay indoors, said Chief Cabinet Secretary Yukio Edano.

If we hadn't nuked them in WWII, they would have eventually done it themselves. Now we know.

The plant consists of six boiling water reactors designed by General Electric according to wikipedia. So I guess we are nuking them again.

Am I the only one that thinks it is stupid to design a nuclear reactor that requires power to cool the radioactive fuel in order to keep it from melting down?

If you can come up with a better design, the world would love you for it.

ETA: as far as I know, even the fourth gen plants are going to require powered decay heat removal.

The reactors didn't explode, only the released hydrogen. And the buildings are designed to do what they did. The buildings only protect the cranes from corrosion.

The question is how did the hydrogen get out of the pressure vessel and sarcophougus? It is my understanding that the concrete shell is seperated from them, so did they intentionally vent the hydrogen into the shell, was there a puncture or leak in the sarcophougus, or did the hydrogen just leech out through the steel by virtue of its small atomic size?

Two of the reactors are Toshiba, one is Hitachi, and three are GE at the #1 plant. So yes, they are nuking themselves.

Even if they meltdown the it should still contain itself if we designed them I mean three mile island held with a partial meltdown, chernobyl was all about dumb ideas, and shotty workmanship. But in any event they are dumping sea water into reactor 3 to cool it which will corrode everything up and make it useless to ever run again, but at least it won't meltdown, sometimes you just have to what you have to do to protect the people.

Why aren't they designed with backup steam turbine coolant pumps fed from the reactor? Why are electric powered pumps in all levels of safety systems? Sort of harvesting the excess heat to cool itself. Pump dynamics may be the limiting factor.

First, there is NO SARCOPHAGUS. Look up what that word means.

These boiling water reactors have a pressure vessel which will withstand over 3500 PSI at 700 degrees F. And that vessel is ideally filled with water vapor and boiling water, in addition to the rest of the contents. Because of the lack of circulation, heat pockets caused hydrogen to build up, this interferes with heat transfer and causes pressure excursions. So the hydrogen must be vented.

They have backup steam turbines... They use them to inject water into the core containment, which is what has kept the situation as controlled as it has been.

To be in this situation, dozens of very robust systems failed to get us here... Mostly because a fucking insane earthquake and tsunami kicked the shit out of the plant.

There is no sarcophagus. There is a containment building. Chernobyl has a sarcophagus because it was built after the reactor exploded.

And that is a bad name there too. Sarco is flesh. Phagus is eater. Bodies are placed into sarcophagi to consume the flesh. A tomb is a better description.

I honestly do enjoy your posts as whole except for this one. Every time a deputy straps on the vest and gets in the patrol car hes in danger. Hell they can't even enjoy a night out on the town with out having contengency plans and watching their back at every turn. I will also say every toneout as a firefighter comes with a chance of danger. The scariest time was a truck that was hauling ass and I was signaling traffic to stop, the trucker was doing about 60 on solid ice and geared down and jaked and he get stopped <10 feet from me as I was making a move to jump the guardrail.

This isn't ANYTHING like Chernobyl. NOTHING like it.

RBMK reactors had no real pressure vessel for the reactor, just upper and lower biological shields surrounded by water tank.

The reactors in peril are boiling water reactors. The "core" is surrounded by the boiling water in normal operation, the reactor vessel MUST be water vapor tight to a pressure of 3200 PSI or more. And the reactor pressure vessels have not ruptured, the explosions are from intentionally vented hydrogen gas

Chernobyl was a tricky plant to operate and once it lost control, it went into over-temperature rapidly, making carbon vapor which then exploded once it leaked. No containment, no pressure vessel as the working fluid was contained in tubes which traversed the core.

On top of all that, even if primary containment fails and the pressure vessel ruptures, the core is still walled in by a bajillion tons of concrete that would surround it on all sides and the bottom... Even if the core is outright exposed, it's staying put... Although that situation would really suck, as it would allow fission byproducts to escape in large quantities into the air.

We're nowhere near it getting that bad though... For that to happen, you'd have to have pressure buildup without the ability to vent it.

Chernobyl, by comparison, was basically a nuclear reactor built inside of a Home Depot... A good tornado hitting it would have wiped it out.

TR85.

A few weeks. The fission reaction creates a good bit of daughter elements which then also contribute to the overall thermal output. Only some of these reactions aren't neutron capture so they cannot be directly controlled. They contribute less than 10% of the total thermal output but without circulation, heat will build up. That is the problem now.

These thermal reactions decrease exponentially after control rods are fully inserted which happened as a programmed consequence of the earth quake. The bulk of the incident is over.

Exactly. The core was cooled by a network of boiler tubes, the pressure containment was inside these tubes with the reactor outside of the tubes. In these Japanese reactors, the core is inside a very large pressure vessel where steam is made from the cooling water that directly contacts the core. The RBMK (Chernobyl) reactor was MUCH LARGER because of this design difference.

You're comparing being a cop to knowingly entering an area of radiation?

Yeah, definitely the same thing...


There were a few hundred men that gave there lives in chernobyl. They were all told they were going to die before they went outside.


i remember watching a documentary which said that they were given medication and suits and were told these would protect them. it also said thousands not hundreds. i don't know which is true but just tossing it out there. facts are not always facts as they seem.

I feel really sorry for these people. I don't think they quite thought it through.


People who have a certain "work ethic" and feel like they have a "responsibility" to do what's "right" to "protect" their "countrymen" from "danger".

By your logic, who in their right mind would ever join the fucking military? Or become a cop? Or a firefighter? Or an EMT?

Soviet soldiers aren't stupid... They knew bullshit when they heard it, I am sure. Just like the guys on K-19.

No matter what you're told, marching into a nuclear reactor in full-tilt meltdown to do engineering work takes a brave sonofabitch. I'm not sure I'd do that.

Are you talking about the documentary where they wrapped up in aluminum foil and ran out the door with a shovel?

There was a documentary on History Channel called "Battle of Chernobyl". It showed footage of
the workers as they cleaned off the top of the plant. Each man had special suits that were actually
lead armor and they would race up and out onto the roof and work for two or three minutes and
then run back off the roof and the next "shift" would go up. They limited each man's exposure to
the radioactive material. It was interesting to say the least. You can watch it on Youtube.

Nothing at all to worry about...

Navy Crewmen Contaminated By Radiation

The radioactivity was detected when the service members returned to the aircraft carrier Ronald Reagan aboard three helicopters. They were treated with soap and water and their clothes were discarded.
