Comment by U.S. Navy Officer indicates seriousness of Radition Leaks

“The immediate action was to get out of the area,” said USN Commander Jeff Davis.  This was part of the explanation of why U.S. ships were moved away from Japan.

In just a few minutes 17 personnel were exposed to a months worth of radiation, even though the helicopters they were in were 60 miles away from the Fukushima nuclear plants.  The radiation clouds are moving eastward, away from Japan, which could explain why radiation levels being taking onshore in Japan look low.

Gregory Jaczko, of the U.S. Nuclear Regulatory Commission, claims there is little threat of radiation spreading to U.S. territories.

If anyone is keeping track of statements made by government officials in the past few years, the track record shows their statements can not, and should not, be trusted.

Loud Bang heard inside Reactor 2

Officials are reporting that a loud bang was heard from inside reactor 2, at Fukushima nuclear plant 1.

It is believed that it is the “Separation Chamber” cracking (some reports call it “Suppression Pool”, some called it the “Pressure Suppression Room”).  Workers at the plant have been moved to “safer” positions, workers not directly involved with cooling efforts have been evacuated.  An official said this chamber is a last line of defense for preventing higher levels of radiation leaking. He also said this could be the worst case scenario taking place.

It was explained that if the separation chamber is breached then contaminated coolant/water with higher levels of radiation can leak out.  The chamber may have cracked due to the intense heat from the exposed fuel rods.  The fuel rods had been fully exposed, more than once.  Workers have been having trouble maintaining levels of coolant, even with pumping in sea water.  Officials claim that the water levels have been brought back up, but at least 2 meters of the rods are still exposed.

Officials keep saying that radiation readings are safe, there in Japan.  They fail to point out that the winds have been blowing the radiation clouds over the Pacific, towards Hawaii. If the winds shift, and blow the radiation towards Japan, then the radiation levels there would increase greatly. The U.S. Navy has moved their ships further away from Japan after several aircrews, on helicopters, were exposed to radiation.

NBC news reported that the reason the back up generators failed is because the fuel tanks were above ground tanks, and were swept away by the tsunami.

Reactor 2 Critical, U.S. Navy says Aircrews exposed to Radiation

NHK reporting that reactor 2, at Fukushima plant 1, is no longer venting and attempts at cooling have failed.  The reactor’s vents closed automatically and can not be opened. Sprayers spraying water on the rods stopped working.

U.S. Navy says U.S. helicopters were hit by radioactive plume while flying over coast line of disaster area. 17 service members tested positive for radiation contamination. The U.S. Navy is now moving their ships further away from Japan. At the time the USS Ronald Reagan aircraft carrier was 160km (100 miles) away.

Japan Nuclear Reactor Safety Systems May Have Caused the Melt Down

NHK is presenting an official ‘explainer’ of why the nuclear safety and backup systems failed. I’ll try to put it simply.

1: Earthquake triggered automatic shut down procedures, which involves raising/exposing fuel rods. This still requires cooling of the rods.

2: Cooling of raised rods failed because main power supply cut. Back up generators came on, but failed when tsunami hit the plants. They could not be restarted.

3: A third backup cooling system failed. This is a steam reclamation system that collects steam off the hot rods, condenses it to water, then sprays the water on the rods. It failed because coolant levels dropped too much for steam to be created. Officials say coolant levels might have leaked due to structural damage caused by the quake and tsunami. They can not be sure what happened to the coolant, until they can inspect the structures.

The failed safety & back up systems are causing the raised fuel rods to partially melt down.  The report suggests that all the reactors along the coast line hit by the quake/tsunami are in partial melt down. An official now says they obviously didn’t expect such a powerful natural disaster when they planned the safety/back up systems. In Fukushima Prefecture alone, one of the hardest hit areas, there are 10 reactors.

There are a total of 55 plants, with anywhere between 2 and 6 reactors each, in Japan. There are 2 plants under construction, with another 11 planned.  In the United States there are at least 104 commercial nuclear plants.  Most of the plants are east of the Rocky Mountains, in highly populated areas.

The failure of all these systems, in Japan, will give anti-nuclear activists plenty of ammo for the demand to end the use of nuclear power plants.

Japan Update: Reactor 2 Now Critical, More Quakes, Survivor’s Stories

200 plus aftershock/quakes greater than magnitude 5 have hit all over Japan (if I heard right, this was in a 24 hour period).  These are not just in the area of the main quake, but all over Japan, another sign of a major geological event.

At least half a million people are in emergency shelters. The shelters are running out of food and water.

At least 15,000 people are officially missing.

Fukushima nuclear plant 1; officials admit that reactor 2 fuel rods melted/permanent damage, caused by a huge drop in coolant levels. Pumping in water failed the first time, because the rods were so hot it all evaporated. They are attempting to pump in more water.

For the first time in Japan’s modern history, reserve military forces are being called up. Also, 13 countries are currently helping with rescue efforts.  As many as 96 countries are offering help.

To help with the economy, which has literally been stopped, the Bank of Japan has injected billions in cash, and has announced that it will increase asset purchases.

There is home video from survivors, which demonstrates the surrealness of the event.  In one video people have run up a hill near their town. They are heard screaming at others to hurry up, “Run, run faster!”, as the wall of water engulfs their town and heads towards the hill they are on.  One survivor said the event made it impossible to think, you just ran.  Another survivor, after seeing the total destruction of her town, and loss of life, said “It would have been better if I died.”.

Reactor 3 Explodes New Tsunami Approaches

Russia Today is reporting that massive smoke is pouring from reactor 3 at the Fukushima nuclear plant 1, Monday morning Japan time.  People living on Russian territory near Japan have received warnings from Japan about a second melt down.

Video on YouTube shows the reactor 3 explosion is bigger than the reactor 1 blast.

RT is also reporting that there are warnings of an approaching tsunami.  Reuters says the claim of an approaching tsunami came from a local Japanese TV station.

Reuters says the announcement of an explosion came from a  Japanese nuclear agency official.  A Canadian news source says the reactor 3 explosion was felt 40km away.  3 plant workers injured, 7 are missing.

Officials are also trying to determine if high radiation levels in Miyagi Prefecture are from a local nuclear power plant, or is coming from the damaged Fukushima plants.

Despite officials downplaying the threat of radiation contamination, hospitals in Miyagi Prefecture are reporting more and more people coming in with radiation poisoning.

Part of the reason why officials are not strongly concerned about radiation is that winds are blowing towards the Pacific Ocean.

Japanese Self Defense forces are also warning of a tsunami, but Japan’s Meteorlogical Agency says otherwise.  Fukushima Prefecture officials claim it could be 3 meters high.

 

 

Fukushima, Idaho

Idaho INL Official statements ominously similar to statements made by Japanese Nuclear Officials

A local East Idaho TV news reporter interviewed an official at the Idaho National Laboratory, regarding the safety of the INL’s nuclear reactor during a seismic event.  INL’s emergency director Riley Chase made almost the same statements that Japanese officials made right before their nuclear disaster.

“If we were to have a seismic event, the safety systems would shut that reactor down…”, also, “…we have diesel generators that run, and we have battery backed-up systems that will provide and constantly keep cooling…”

I’d like to remind people that this is what the officials said in Japan.  Their safety systems and back up systems failed.  This is because the quake and tsunami in Japan was much stronger than anyone planned for.  The Japanese systems were set up to withstand a 7.9 quake. It is now clear that the event was much, much stronger.  I believe if we in Eastern Idaho experienced such a strong event the INL system would fail as well. A major fault line does run through East Idaho, from Salt Lake up to Yellowstone.

On the plus side, the INL reactor is low power, and is run for 6 weeks each time it’s powered up.  So hope that the big one hits when the reactor is shut down.

By the way, the INL reactor is not the only nuclear plant in East Idaho.  Idaho State University has a graphite reactor on its Pocatello campus.  Shouldn’t be much concern, their ANG-201 reactor produces only 5 watts of power (at least that’s the maximum it is allowed to produce).

I have talked to long time building maintenance employees at the University, and they have told stories of the radioactive waste, from ANG-201, being stored in unmarked buildings. The story I heard was that some maintenance employees were on the roof of a building when they were suddenly told to get off the building. They were sent for medical exams, where they learned they were being checked for radiation exposure. Apparently the building they were on was being used to store radioactive waste.

This brings up the issue of radioactive waste.  In the United States storage of radioactive waste has become a problem, because no one wants it in their back yard. So what happens to it? Some nuclear plants in California have simply been building up a stockpile of waste on their property. Here in East Idaho, the INL has been dealing with the problem of  contaminated waste for decades. If the U.S. experiences a major seismic event near nuclear plants, not only will the reactors become an immediate threat, so will the waste.

Japan Nuclear Disaster Update, it’s Bad Bad Bad

As of 1600 Mountain Time, March 13, here is what Japan’s NHK is reporting on the status of Fukushima nuclear plants.

Plant 1:

Reactor 2 coolant levels low. Pressure and gas build up. Use of external generators failed.

Reactor 3 possible explosion imminent. Pressure and gas build up. Relief valves malfunctioning. Coolant levels dropping. Sea water having little affect. Nuclear power rods exposed by 2.2 meters, partial meltdown occurring.

Reactor 1, exploded, sea water being pumped in to flood reactor, but it is taking longer than expected.

Plant 2:

Reactors 1, 2 and 4 cooling system failure.

Iodide Not Iodine

Once again the U.S. media has been getting it wrong; saying that people in Japan are being issued “Iodine” pills. No, it’s “Iodide” pills!

Iodine and Iodide are related, but are different. Both can be good for you, and bad for you. It depends on the form, dosage and how they are used.

Many people think Iodine is good for you, in extreme small doses, and, in fact Iodine deficency can cause health problems. But, some forms of Iodine, like Iodine 131 (used in nuclear reactors), are bad and can cause cancer.  Iodine is not used in table salt.

Some table salts are enriched with Potassium Iodide. It is called “Iodized Salt”.  The general public has mistakenly called it iodine salt.

Potassium Iodide is what is used in anti-radiation pills. This is what the people, near the crippled nuclear reactors in Honshu, are being given. 

The thyroid gland in animals (that’s us humans as well) uses trace amount of Iodide to create proteins and hormones that contains Iodine. Hyperthyroidism can occur with an increase in Iodine consumption.  In other words, this substance is finicky when it comes to the health of humans. It can prevent cancer, and, it can also cause cancer and glandular problems, it depends on how much the person is ingesting, or is exposed to.

The lesson here is: Use Iodine and Iodide only when necessary, like in the case of diagnosed Iodine deficiency, or as a disinfectant (Lugol’s Iodine), or to prevent radiation poisoning in a nuclear event (Potassium Iodide). Otherwise, do not eat or drink it on regular basis.

Do your research.

Japan Tsunami Much Higher than Officially Stated!

Japan’s NHK has interviewed survivors on the coast of North East Honshu.

Survivors in one coastal town say they have been told that the official tsunami height was put at 4 meters, for their area.  They say that can not be, because sea wall tsunami barriers are built 10 meters high, and the tsunami easily went over the 10 meter high sea walls.  One resident says the tsunami that hit their town had to be at least 14 meters high.

1 meter = 3.28 feet.  14 meter wave is 45.9 feet high.
