Fukushima: Reactor 4 -Cooling Suspended-


Japan has restarted its other nuclear plants, despite the ongoing emergency at the Fukushima Daiichi Nuclear Power Plant that was very badly damaged on March 11, 2011 by the 9.0 earthquake, tsunami, (stuxnet and co.?) and failure of the plants operators to contain the situation 500 days later.

Tepco has stopped the cooling system supplied to the badly damaged Reactor 4 at Fukushima.  They cannot activate a backup cooling system and they are looking into the cause.  On June 25, Tepco removed an upper portion of reactor 4 and it is suspected they damaged the pipes of the cooling system.

Expect an announcement to be made very soon about their plans for the destruction of reactor 4.

If Reactor 4 experiences a complete meltdown then Japan will be over.  Then the northern hemisphere and finally the world.

By July 5, the temperature could reach 100 C.

Meanwhile reactor 1 is releasing  radiation at over 260 times “normal” amounts, due to a leak in the basement.  This is further hampering efforts to slow down the release of the nuclear fuel.

The annual allowed dose for workers at the stricken site is reached in only 20 seconds.

It’s time for Tepco to step aside and take an offer from someone else to clean up this mess as much as possible.  The one thing Tepco has done well is show the world that they are incompetent.  What do you do with radioactive waste?  Nuclear power has no long term benefit for this planet.

Typhoon Guchol Ripping Across Japan Radiation is Spiking


Image

Typhoon Guchol is making its way northeast over the island of Japan at around 50 mph, with winds of 120 mph.  150,000 residents have been ordered to evacuate and the public transportation has been halted from Toyko to  the northern prefectures.

Tepco has not held a press conference or released any information regarding its devastated nuclear power plant.  At this point I assume any information will come from leaks or we will not find out the truth for weeks or months.

If you have a geiger counter, start taking readings today and for the next 40 days (the time it takes the radiation to circle the northern hemisphere) and post your results here and  anywhere you can.

The storm is kicking up radiation as you can see on the charts.  Visit this guys blog:

More bad news as Japan failed to disclose the radiation maps taken by the United States directly after the March 2011 earthquake, tsunami and nuclear disaster.   The maps could have possibly aided in the rescue efforts.   The largest amounts of radiation flew northwest back on top of the island of Japan.   http://www3.nhk.or.jp/daily/english/20120619_23.html

Typhoon Guchol and Further Disaster at Fukushima Possible


Image

This could be potentially very devastating for the northern hemisphere.  Fukushima’s damaged reactor and waste pools are still leaking, if this typhoon hits, most likely it will be damaged further, perhaps destroyed completely, leaking out the rest of the radiactive materials into the air and pacific ocean. Maybe its time to go to the southern hemisphere.

Powerful Typhoon GUCHOL (BUTCHOY) has strengthened rapidly into a dangerous 220-km/hr howler…likely to become the 1st Super Typhoon of 2012. Thick Monsoon Rainclouds approaching Western Luzon including Metro Manila and Mindoro (philippines)

GUCHOL (BUTCHOY) will enhance the Southwest Monsoon (aka. Habagat) across Visayas & Luzon particularly the western sections tonight until Tuesday. Breezy to windy conditions & cloudy skies w/ occasional to widespread rains, thunderstorms & squalls will be expected. The seas along the coastal areas along the West Philippine and Visayan Sea will become moderate to rough & dangerous.

Residents and visitors along the East Coast of the Philippines and the Southern Islands of Japan, particularly Okinawa and Ryukyu should closely monitor the progress of GUCHOL (BUTCHOY).

Do not use this for life or death decision. This advisory is intended for additional information purposes only. Kindly refer to your country’s official weather agency for local warnings, advisories & bulletins.

The following Consequences are identified for a Loss of Spent Fuel Pool Level:

* risk of a fire in fuel pool number 4 is real, and that the risks of contamination are so severe that an international effort is required.

* a nominal release of 10% of the SFP 4 inventory of cesium and strontium would represent 3-10 times the March 2011 release amounts

Spent fuel pools are not protected in the same way as reactor cores, and the unit 4 building is seriously damaged

* the fuel rods currently produce about one megawatt (MVV) or more of waste energy in the form of heat (1,000,000 Watts!)

* If cooling water for the spent fuel pool is lost – either by collapse of the pool, formation of cracks in the pool, or other factors – a major release of radioactive material could result. Given the large amount of heat generated by the fuel rods, the temperature would rise quickly. These rods are surrounded by zirconium cladding, and at high temperatures, this cladding catalyzes hydrogen production, can generate additional heat, and even explode and burn (NRC, 2006).

* The water surrounding the fuel rods in the spent fuel pools serves two purposes: First, it conducts heat away from the fuel assemblies to avoid overheating. Second, it provides shielding from the extremely high radiation levels near the rods.

* loss of shielding by the cooling water could critically increase radiation levels in the entire Daiichi complex. High radiation is already a serious problem limiting worker and even robot access to the plant to perform repairs and mitigation, and to maintain cooling of the other spent fuel pools and reactors. Thus, a catastrophic failure of the unit 4 spent fuel pool could potentially cascade into additional releases from the other spent fuel pools and reactors.
