How is that ironic? Questioning what the media tells you and doing your own reading and research is what everyone should be doing. I'm no fan of Beck but that was his message don't trust the media, the Doomsayer is your label.

Ironies are (at least) as follows:

1) Beck, the doom-and-gloom guy of the decade,has made God knows how many millions touting a company selling WAY overpriced gold and -- that's right -- seeds, freakin' seeds! And he is advancing commentary that downplays some doom and gloom?

2) Beck says he figured this out by reading a book. Wait, what? Beck go do some independent research to learn facts?

3) Beck defenders are touting Beck on this issue because he read from a book. Hahahahahahahahaha !!

4) Anyone thinks Beck went and did this research himself. Hhahahahahahahaha !!!

5) People think Beck has a clue what he is talking about on this.

6) People think Beck (or more accurately his staff) didn't cherry pick what he read. Hahahahahahahaha !!

7) Beck claiming that radiation from a post-Soviet nuclear accident isn't really all that bad. Wait, he hates them!

8) People watching Beck for either news, or insightful commentary. And then going with that instead of what the IAEA and members of the Nuclear
Regulatory Commission have to say about all of this.


I got more if you want 'em ....

Or maybe that he is contrarian for the sake of being contrarian?

If he says what everybody else says, he'd be mighty boring. Its no secret that his ratings have sunk pretty badly lately. Just sayin'.....

I realize critical thinking and reading comprehension isn't your forte, so I will try to make this as clear as I can. Nobody on this forum has professed to like Beck. The subject of my post was the book and the commentary of the author Beck read on air. I gave you the context within which it was made, that Beck thinks people should question the media and do your own research, which I happen to agree with you.

If you want to go on a rant about Glenn Beck do it in a forum where people actually like him or care enough to defend him because I don't and I'm pretty sure you will find no one else here does either.

Someone had asked about the amount of fuel in the reactors and storage pools. Here are the numbers.

R# Assemblies in core. Assemblies in pool Tons of fuel in pool.

R1: 400 292. 50
R2: 548. 587. 100
R3: 548. 514. 90
R4: 0. 1479. 250

Sounds like they're slowly gaining control at the plants.

Fukushima's 2 reactors under control after cooling functions restored

TOKYO, March 20 (Xinhua) -- The No. 5 and No. 6 reactors at the quake-damaged Fukushima Daiichi nuclear plant went into stable condition on Sunday, local media reported.

The two reactors went into cold shutdown following restoration of cooling functions late Saturday, thanks to successful resumption of electricity supply, authorities said.

Earlier in the day the defense ministry said that it succeeded in putting water into the No. 4 reactor at the troubled Fukushima nuclear power plant.

In a separate move, the Tokyo Fire Department shot over 2,000 tons of water into a spent fuel pool of the No. 3 reactor in an overnight mission that lasted more than 13 hours until 3:40 a.m. local time Sunday.

Tokyo Electric Power Co. (TEPCO), owner and operator of the plant, was also trying to restore electricity to the No. 1 and 2 reactors to restart the cooling system.

The plant, about 220 km northeast of Tokyo, was stricken by the twin disasters of the catastrophic March 11 earthquake and ensuing tsunami.

Radioactive leaks were detected after a series of explosions and fires at four of its six reactors following the failure of their cooling functions due to the damaged power supplies.

The authorities advised residents living within 20-30 km radius of the plant to stay indoors and set the area 20 km around the plant as an exclusion zone where residents have been evacuated.

5 and 6 were the low hanging fruit. No damage, just power loss. So, getting them back up means a viable power source (direct line + diesel generators) has arrived.

It feels like reactors 1-4 may be able to be controlled, but that is a much more involved and risk-prone operation. There is really no way to directly parlay success at 5 and 6 into success at 1-4, with the exception of possibly reactor 2, and even that is likely a stretch for now. Still a long row to hoe, but despite that, the prospects of avoiding significant, wide-spread offsite contamination are looking good at the moment.

Without knowing the scaling, kinda hard to judge... I mean, what does a thermal image of a well-functioning reactor look like? I dunno.

it shows that something is going on inside the reactor #2 building and that the other reactors are hot, but manageable

Hmm...is that the official conclusion? That's not what I would take away from that - at least not at first glance. Building 2 is the only building whose secondary containment (the building it is in) is not damaged. Reactor 1 and 3 buildings are blown away and most of the top floor of reactor 4 building is blown out.

It seems that the heat that is being generated inside building 2 is being trapped inside the building, heating it, and causing a uniform, warm heat signature for the building. On the other hand, reactors 1, 3, and 4 are fairly open to release the heat they are generating right out to atmosphere. So, all you see if the hotspots that are producing the heat rather than the signature of a warm building.

This doesn't mean that nothing is wrong inside reactor 2 (it really shouldn't have a heat signature like that, I wouldn't think). They are likely venting steam (either intentionally or unintentionally) and heat the building. But, if the others had roofs...they could fairly well look the same. For example, as I understand it, reactor 3 building (reactor and fuel pond) is in pretty rough shape.

not offical just a guess on my part. The white is over 200 C according to the NHK World website, so 1 and especially 3 have hot spots while #2 is a sauna

apparently they have hooked up power to all reactors today.

If they could shoot the internals of 2 directly, I would say that you would see similar hotshots. I'm just not sure what normal hotshots and abnormal hotspots look like for this system. For example, since they are venting the reactor into the primary containment, it is probably expected that the reactor primary containment head would be hot.

I forgot to post this... We have a whistle blower

Fukushima Engineer Says He Helped Cover Up Flaw at Dai-Ichi Reactor No. 4 - Bloomberg

One of the reactors in the crippled Fukushima nuclear plant may have been relying on flawed steel to hold the radiation in its core, according to an engineer who helped build its containment vessel four decades ago.

Mitsuhiko Tanaka says he helped conceal a manufacturing defect in the $250 million steel vessel installed at the Fukushima Dai-Ichi No. 4 reactor while working for a unit of Hitachi Ltd. (6501) in 1974. The reactor, which Tanaka has called a “time bomb,” was shut for maintenance when the March 11 earthquake triggered a 7-meter (23-foot) tsunami that disabled cooling systems at the plant, leading to explosions and radiation leaks.

Tanaka says the reactor pressure vessel inside Fukushima’s unit No. 4 was damaged at a Babcock-Hitachi foundry in Kure City, in Hiroshima prefecture, during the last step of a manufacturing process that took 2 1/2 years and cost tens of millions of dollars. If the mistake had been discovered, the company might have been bankrupted, he said.

Inside a blast furnace the size of a small airplane hanger the reactor pressure vessel was being treated one last time to remove welding stress. The cylinder, 20 meters tall and 6 meters in diameter, was heated to more than 600 degrees Celsius (1,112 degrees Fahrenheit), a temperature that softens metal.

Braces that were supposed to have been placed inside during the blasting were either forgotten or fell over when the cylinder was wheeled into the furnace. After the vessel cooled, workers found that its walls had warped, Tanaka said.

Warped Walls
The vessel had sagged so that its height and width differed by more than 34 millimeters, meaning it should have been scrapped, according to nuclear regulations. Rather than sacrifice years of work and risk the company’s survival, Tanaka’s boss asked him to reshape the vessel so that no-one would know it had ever been damaged. Tanaka had been working as an engineer for the company’s nuclear reactor division and was known for his programming skills.

“I saved the company billions of yen,” said Tanaka, who says he was paid a 3 million yen bonus and presented with a certificate acknowledging his “extraordinary” effort.

despite the flaw, it still survived a 9.1 magnitude quake and had the secondary generators not failed, we wouldn't be having this conversation.
