Precarious state of Fukushima’s nuclear fuel rods

The workers are like Samurai warriors, they’re like suicide workers. They know they are getting huge amounts of radiation going to the site. They can only go in, seconds to minutes, at a time doing work and then the next batch has to come in.

Chernobyl had a half a million workers who worked minutes at a time. Here we have a situation much worse than Chernobyl simply because we have basically five reactors that could go up. One reactor setting off the next reactor, that’s a huge amount of radiation, over ten times the radiation inventory found in Chernobyl.

“People don’t realize that the Fukushima reactor (Number 4) is on a knife’s edge; it’s near the tipping point.

May 20, 2012 By LBG1 We could have a disaster much worse, many times worse than Chernobyl.” Dr. Michio Kaku on the precarious state of the spent fuel rods in the severely damaged Fukushima nuclear reactor Unit Number Four building

Recently, TEPCO released a petulant press release they plan to inspect the heavily damaged reactor Unit Number Four for signs of tilting. The press release coincided with photos published on the web purportedly showing a large crack running from the foundation to just below the fifth floor of the south wall of the Unit Number Four building where all the spent fuel rods on the site are stored, “open to the elements because a hydrogen explosion blew off the roof during the early days of the accident and sent the building into a list”.

If there isn’t a large crack there is still the issue of the severely damaged Unit Number Four building ’tilting’. The 1500 spent fuel rods pond almost suspended in air on the fifth floor and the extreme potential for a slight earthquake or explosion to unleash a catastrophic radioactive chain of events ‘much worse than Chernobyl’.

From a May 5, 2012, must-read article written by Brad Jacobsen at Alternet, The Worst Yet to Come? Why Nuclear Experts Are Calling Fukushima a Ticking Time-Bomb:

“The spent fuel in the hobbled unit 4 at Fukushima Daiichi not only sits in an elevated pool outside the reactor core’s reinforced containment, in a high-consequence earthquake zone adjacent to the ocean — just as nearly all the spent fuel at the nuclear site is stored — but it’s also open to the elements because a hydrogen explosion blew off the roof during the early days of the accident and sent the building into a list.”

The upcoming TEPCO inspection, one of the four-times-a-year TEPCO inspects the damaged nuclear reactor building until the spent fuel rods are removed. Four times a year in a location of continued aftershocks from the March 11, 2011, 9.0 Japan earthquake-as of May 8, 2012, 60 aftershocks over magnitude 6.0 and three aftershocks over magnitude 7.0.

Aftershocks related to the 9.0 quake will continue for years including the potential for another ‘big one’. The duration of the March 11, 2011, 9.0 quake: 3 minutes; the earthquake epicenter 130 km offshore of the city of Sendai in Miyagi prefecture on the eastern cost of Honshu Island.

One of the reasons why there are only four inspections a year could be the ongoing radiation inferno that fried the iRobot Packbots, according to Dr. Machio Kaku.

Dr. Michio Kaku, Flashpoints Daily News Magazine Interview:

Humans cannot come close to certain parts of the reactor site and even robots get fried. They’re delicate machinery; their micro-circuitry cannot withstand the intense bombardment of radiation. We’re talking about thousands of rads of radiation per hour being registered there and that is affecting the cleanup operation.

“It will take years to invent an new generation of robots” able to withstand the radiation.

The workers are like Samurai warriors, they’re like suicide workers. They know they are getting huge amounts of radiation going to the site. They can only go in, seconds to minutes, at a time doing work and then the next batch has to come in.

Chernobyl had a half a million workers who worked minutes at a time. Here we have a situation much worse than Chernobyl simply because we have basically five reactors that could go up. One reactor setting off the next reactor, that’s a huge amount of radiation, over ten times the radiation inventory found in Chernobyl.

Kaku, a noted physicist, explained why the world should be concerned about the current situation at Unit Number Four:

“People don’t realize that the Fukushima reactor (Number 4) is on a knife’s edge; it’s near the tipping point. A small earthquake, another pipe break, another explosion could tip it over and we could have a disaster much worse, many times worse than Chernobyl. It’s like a sleeping dragon.

Just in the last few weeks it’s been in the paper to some degree, Units 2, 3, and 4 have been shown to be in a very dire situation. Unit 2, we now know completely liquified. We’ve never seen this before in the history of nuclear power, a 100% liquefaction of a uranium core. Unit 3, on the other hand, Unit 4, on the other hand, has an even worse problem, and that it’s a spent fuel pond that is totally uncovered because of a hydrogen explosion that took place last year. The 1,500 rods that could be exposed to the air and then set off another spent pond with 6,000 rods. Altogether there are 11,000 rods in the Fukushima site that could be tipped over. A slight earthquake, a light explosion could set the whole reactor back into motion. And also, in regards to Unit 3, we found where we thought there was 33 ft. of water above the core. We put a TV camera in Units 2 and 3. We have TV pictures of the core; Unit 2 is completely liquified, Unit 3 does not have 33 ft. of water on top of it, it has two feet of water. TWO FEET of water, not thirty-three, meaning that the core is completely, or partially covered, meaning it could liquify. So between Units 2, which is completely liquified, Units 3, which is totally exposed, and Unit 4, which has 1,500 spent fuel rods that, in principle, are exposed to the outside environment, we have a catastrophe in the making.”

Radiological Event Could Be Five Times As Dangerous As Chernobyl:….
