Japan official: Flooding Reactor 1 with more water is a wasted effort, due to total melt down?

Officials with Japan’s Nuclear and Industrial Safety Agency say it’s too late now that fuel rods in Fukushima Daiichi Reactor 1 have melted down!  Tokyo Electric Power Company officials wanted to pump more water into the reactor, in the hopes of stopping the meltdown.

Nuclear Safety officials think the melted rods have cooled enough in the water at the bottom of the reactor, that there might not be too much concern.  However, TEPCo believes that holes in the reactor vessel have been created by the meltdown, which is causing large amounts of radioactive water to pour into the Pacific Ocean.

The Agency suggested that TEPCo should inject water only to the point of keeping the bottom of the reactor filled.

Cesium spreading across Japan!

Two prefectures bordering Fukushima Prefecture, have discovered that plants are contaminated with cesium.

Tochigi and Ibaraki Prefectures have cesium contamination well about safe limits.  As much as 3,600 becquerels of cesium has contaminated pasture land, and crops!  The government’s safe limit is 300 bequerels.

Farmers are being told not to feed their animals the grass.  Crops are so contaminated that farmers are being told not to harvest, or ship their crops.  Some contaminated parsley had already been shipped to market.

 

 

 

 

Fukishima Daiichi Reactor 1 officially in Meltdown

13 March 2011, Tokyo Electric Power Company has announced that fuel rods in reactor 1 have melted.  Government officials think this might be the cause of holes where highly contaminated water is pouring from.

TEPCo officials say that most of the fuel rods have melted and are now melting through the bottom of the reactor.  Officials think the melted rods are cooling down at the bottom of the reactor because there is still water there.

TEPCo is now trying to find out how much water is actually in the reactor, and come up with a new plan to address the meltdown.

Fukushima Daiichi Reactor 3 still flooding ocean with Cesium!

Even after Tokyo Electric Power Company plugged a leak, Reactor 3 is still pouring water contaminated with cesium into the Pacific Ocean.

The water is pouring out of a pipe containing electrical cables, but officials still don’t know where the water is originating.  The latest tests of the ocean water showed cesium contamination at 620,000 times safe limits!

Fukushima Daiichi Reactor 1 springs mysterious leak, fuel rods fully exposed, melting!

Tokyo Electric Power Company says contaminated water is pouring from Reactor 1.  This after workers were finally able to enter the building and check gauges.  The gauges showed that despite hundreds of tons of water being injected, the water levels were low.

TEPCo suspected faulty gauges. Workers checked the gauges again, after more water was pumped in, and they discovered the water levels actually dropped.

Now officials are worried that the water could be pouring from a hole in the reactor itself.  When checked on the morning of 12 May, workers discovered the fuel rods fully exposed.   Water levels are a full meter (3.2 feet) below the rods!

TEPCo is pumping in water, but the Nuclear and Industrial Safety Agency believes rods have started melting.

U.S. nuclear plant under NRC scrutiny

The Brown’s Ferry nuke plant in Alabama, is under investigation by the Nuclear Regulatory Commission.  Investigators say a cooling system failure is of “high safety significance”.

Last October the plant had a cooling valve problem, in reactor 1, that cause it to shut down.  Operators say the valve is fixed.  But there are concerns especially since the Brown’s Ferry plant is similar to the GE designed Fukushima Daiichi plant in Japan.

Also, Brown’s Ferry Reactor 1 had been shut down for 22 years before being put back into operation in 2007.

 

 

 

TEPCo finds out hard way that it’ll take much longer to get control of Fukushima Daiichi

On 17 April, Tokyo Electric Power Company issued a plan to control the damaged Fukushima Daiichi plant.  That plan involved 51 steps, so far as of 10 May, only one is being done; the continued pumping of water to try and cool the reactors and fuel pools.

TEPCo admitted they did not expect such high levels of radiation inside the reactor buildings, and that has been the big hold up.  They can’t do much with such high levels of radiation.

Workers have finally entered the building of Reactor 1, but that is only to help with the water injection and cooling operation.  In other words, still stuck on step one of their 51 step plan.

Government instructs schools to simply bury their radioactive top soil! government experts have their head up their a…

Schools near the damaged Fukushima Daiichi nuke plant have found radiation contamination in the top soil of their playgrounds.

Normally you remove the top soil and have it hauled away in sealed containers, as nuke waste.  But that’s not what the Japanese government is suggesting.

School officials are being told by the government to simply bury the radioactive soil deeper in the ground.  They say by burying it 50 cm (19.6 inches) into the ground, it will reduce the detectable radiation by 90%.  The suggestion is being made by the Japanese Education and Science Ministry (can you believe that!).

Hello, what happens when a child digs it up?  Or a dog?  This sounds like an expedient way to simply reduce detectable radiation levels, it’s still there waiting for someone to accidentally dig it up!

What about water soaking down through the soil, eventually hitting the ground water?  It’s going to pass through the buried radiation contamination, dragging some of it along with it to the ground water.

 

More than half Japan’s nuclear plants down!

How could a few shut down nuclear plants have such drastic affects on Japan’s industries?  When it’s more than a few, try 60%.

Electrical power shortages will continue thru summer.  Japan has 54 commercial nuke plants, right now 32 are shut down.  Some, like Fukushima Daiichi, were shut down by the 11 March disasters.  Others are down for scheduled maintenance, or government orders.

On top of that, six more plants are scheduled to shut down for maintenance this summer.

 

Radiation contamination in fuel pool coming from reactor core!

Tokyo Electric Power Company admits high levels of radiation contamination in Reactor 3 spent fuel pool, are coming from the reactor’s core!

TEPCo recently tested the water of the spent fuel pool, and found radiation that was not present prior to the 11 March disasters, which damaged the Fukushima Daiichi nuclear plant.

The readings are 140,000 becquerels of radioactive cesium-134, 150,000 becquerels of cesium-137 and 11,000 becquerels of iodine-131 per cubic centimeter.  The clue that the radiation is coming from the reactor core is the iodine.  Iodine is a short life radioactive isotope, and is created during nuclear fission.  (don’t confuse iodine with iodide)
