Meltdown Likely Under Way At Japan Nuclear Reactor


Recommended Posts

The plant operator said water levels fell as fuel for pumps that are used for seawater injection operations ran out.

You'd think they'd gotta be joking about this... But, they're not... They ran out of fuel???

Just exactly how could that happen under the circumstances?

Countries are bracing for radioactive leaks from nuclear power plants in Fukushima.Russia is monitoring radiation levels every hour round the clock in the Far East. A French team of 12 experts trained to deal with nuclear accidents is arriving in Japan.

It sounds like TEPCO has made some kind of statement about radioactive emissions and/or monitoring levels around the plant tonight, apparently associated with the fuel rods being exposed at Reactor No. 2.

But thus far, I'm not finding the details of that... Still looking... That's apparently part of what prompted the just concluded Edano news conference.

Reuters:

A roundup of emerging international attitudes towards nuclear power production.

Turkish energy minister Taner Yildiz says his country, itself earthquake-prone, remains determined to build nuclear power plants. The country has previously said it wants nuclear to contribute the majority of its power production, and is looking to build 20 reactors by 2030.

Reuters' own government sources have echoed the reports that German Chanceller Angela Merkel will later today suspend her decision to extend the life of the country's nuclear power plants.

Switzerland has already suspended the approvals process for three new nuclear power stations so that it can revisit its safety standards.

NISA news conference on Daiichi Reactor No. 2

At 5:16 pm (Japan time), the water level had fallen so the tops of the fuel rods were exposed.

Then at 6:06 pm, the safety relief valve to release steam was opened, lowering pressure in the reactor.

From 8:05 pm, we began re-injecting sea water...

Company earlier held a news conference that included saying there had been release of radioactive elements.

Kyodo News:

--Water level of about 2 meters recovered at No. 2 reactor of nuke plant

--Fukushima's 3 reactors highly likely facing melting: Edano

--Worst-scenario for Fukushima plant unlikely to be like Chernobyl: Edano

--Radiation around nuke plant at tolerable level for humans: Edano

The one in red is a right statement. It will be worse due to higher tensity of the population.

What about the ecological damage so far which were likely caused by chemical, oil etc.?

I dread to contemplate the loss of life from disease caused by the flooding of the sewer systems n Japan, at a time when medical facilities will be stretched to bursting point.

Let's hope the other reactors that were not so badly affected can be restored to service quickly, and power restored to support the clean-up operations. I'm sure the Japanese will be grateful for the high standards of their seismological research and engineering design standards when the recovery begins.

On my previous-but-one project, we adopted Japanese seismic engineering standards, which stood the job in good stead subsequently

I commend the workers at the disabled Nuke power plant for hanging in there so valiantly.

Also, it's commendable that there haven't been reports of looting. In NYC, if there's a power blackout for just ten minutes, looters come out en masse. You might say, "what's there to loot, when everything is destroyed and covered in mud?" Well, more than a few people keep gold coins and money in their homes, besides other valuables. And yes, Japan's cops and soldiers are to be commended for doing what needs to be done in such catastrophic scenarios.

Re; the damaged plant facilities: To pump vast quantities of sea water, they would need gas or diesel powered generators, as there's unlikely any AC power to the facilities. So they likely need large quantities of fossil fuels to try and do all that pumping. They'll also need at least a few men to stay close to dangerous areas - which harkens back to the first sentence of this post.

and I concur with an earlier poster who expressed concern about all that sea water - now highly contaminated - going back to the sea. Interestingly, most of the proposed Thai Nuke plants are planned to be sited seaside. Good luck to fish eaters - but it's bigger issue than just fish. Many organisms need clean water to grow. This is a bigger issue than just one species (humans) concerned about what's on their dinner plate.

Don't blow up anything while I'm away...

We'll just vent some gas.

Don't do it near where you keep the candle burning at both ends.

  • Timestamp: 10:20pm Yukiya Amano, the IAEA director general, has released the following statement. We're expecting him to give a press conference in the next few hours. We'll bring you it as it happens.

Fuel rods at No. 2 reactor fully exposed for about 2.5 hours [late this afternoon]: agency

NHK:

TEPCO is considering opening a hole in the reactor housing building to release hydrogen generated by the exposed fuel rods.

Might be a wise move, why have another big explosion you know will be coming. Venting the pressure before it gets too much will cause less damage to surrounding parts of the system.
