Favorable winds over Japan carrying radioactivity out to sea

By: Dr. Jeff Masters , 2:16 PM GMT on March 16, 2011

If there is going to be a major nuclear disaster with massive release of radioactivity into the atmosphere from Japan's stricken Fukushima nuclear plant, today would be the best day meteorologically for this to occur. The low pressure system that brought rain and several inches of snow to Japan yesterday has moved northeastwards out to sea, and high pressure is building in. The clockwise flow of air around the high pressure system approaching Japan from the southwest is driving strong northwesterly winds of 10 - 20 mph over the region. These winds will continue through Thursday, and will take radiation particles emitted by the stricken reactors immediately out to sea, without lingering over Japan. Since high pressure systems are regions of sinking air, the radiation will stay close to the ocean surface as the air spirals clockwise over the Pacific. The contaminated air will remain over the ocean for at least five days, which is plenty of time for the radiation to settle out to the surface.


Figure 1. Surface weather map for 8am EDT today, taken from the 6-hour forecast from this morning's 6 UTC run of the GFS model. A high pressure system to the southwest of Japan, in combination with a low pressure system to the northeast are driving strong northwesterly surface winds over the country. Image is from our wundermap with the "Model" layer turned on. The lines are sea-level pressure (blue contours, 4 mb interval) and 1000 to 500 mb thickness (yellow contours, 60 m interval). Thickness is a measure of the temperature of the lower atmosphere, and a thickness of 5400 meters is usually close to where the dividing line between rain and snow occurs.

Thursday night and Friday morning (U.S. time), the high pressure system moves over Japan, allowing winds to weaken and potentially grow calm, increasing the danger of radioactivity building up over regions near and to the north of the nuclear plant. On Friday, the high departs and a moist southwesterly flow of air will affect Japan. These southwesterly winds will blow most of the radiation out to sea, away from Tokyo. Southwesterly winds will continue through Sunday, when the next major low pressure system is expected to bring heavy precipitation to the country. Beginning Thursday night, the sinking airmass over Japan will be replaced a large-scale area of rising air, and any radiation emitted late Thursday through Friday will be carried aloft towards Alaska and eastern Russia by this southwesterly flow of rising air.

Ground-level releases of radioactivity are typically not able to be transported long distances in significant quantities, since most of the material settles to the ground a few kilometers from the source. If there is a major explosion with hot gases that shoots radioactivity several hundred meters high, that would increase the chances for long range transport, since now the ground is farther away, and the particles that start settling out will stay in the air longer before encountering the ground. Additionally, winds are stronger away from ground, due to reduced friction and presence of the jet stream aloft. These stronger winds will transport radioactivity greater distances. I've made trajectory plots for the next three days assuming two possible release altitudes--a surface-based release near 10 meters, which should be the predominant altitude in the current situation, and a higher release altitude of 300 meters, which might occur from an explosion and fire from a Chernobyl-style incident. Given that the radioactivity has to travel 3000 miles to reach Anchorage, Alaska, and 5000 miles to reach California, a very large amount of dilution will occur, along with potential loss due to rain-out. Any radiation at current levels of emission that might reach these places may not even be detectable, much less be a threat to human health. A Chernobyl-level disaster in Japan would certainly be able to produce detectable levels of radiation over North America, but I strongly doubt it would be a significant concern for human health. The Chernobyl disaster only caused dangerous human health impacts within a few hundred miles of the disaster site, and the distance from Japan to North America is ten times farther than that.

The plumes initially spiral clockwise around the high pressure system to the southwest of Japan and stay near the surface. By Saturday, though, the plumes get caught in a southwesterly flow of air in advance of an approaching low pressure system. Ascending air lifts the plumes to high altitudes, where winds are stronger and rapid long-range transport occurs. Images created using NOAA's HYSPLIT trajectory model.

The plumes get caught in a southwesterly flow of air in advance of an approaching low pressure system. The plume emitted near the surface (red line) stays trapped near the surface, but the plume emitted at 300 meters is lifted to 3.5 km altitude by the rising air associated with the approaching low pressure system.

Rare subtropical cyclone forms near Brazil
An unusual low pressure system that came close to becoming a tropical storm is in the South Atlantic, a few hundred miles east of the coast of Brazil. The Brazilian Navy Hydrographic Center has officially named the system Subtropical Storm "Arani", but I'm not sure the low would have been named by NHC, since Arani has somewhat of a loose circulation and limited heavy thunderstorm activity. The storm is expected to move slowly eastward out to sea, and does not pose a threat to South America. The latest run of the GFDL model shows little development of Arani, and the storm is now encountering a frontal system, which is bringing 20 - 30 knots of wind shear. It is unlikely that Arani will become a tropical storm. Some runs of the GFDL last weekend were predicting Arani would intensify into a Category 3 hurricane; that's the first time I've even seen such a prediction for a South Atlantic storm. The metsul.com blog has more info on Arani, for those of you who read Portugese.


Figure 5. During the daytime on Tuesday 15 March 2011 at 1820 UTC the TRMM satellite flew over a rare cyclone labeled Arani in the South Atlantic. Arani had the appearance of a tropical cyclone but has been classified as a subtropical cyclone. NOAA's Satellite and Information Service classified Arani as a T1 on the Dvorak intensity scale which would indicate an estimated wind speed of about 29 kt (~33 mph). TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data were used in the image above to show rainfall near Arani. Image credit: NASA.

U.S. troops kept far away from Japan's burning nuclear reactors
By Larry Shaughnessy, CNN Pentagon Producer
March 16, 2011 2:31 p.m. EDT



Washington (CNN) -- Concerned about potential radiation exposure, the U.S. military will not allow troops to get within 50 miles of the damaged Fukushima Daiichi nuclear plant, Col. David Lapan, a Pentagon spokesman, said Wednesday.

The exclusion zone matches the area from which the U.S. Embassy in Tokyo is advising American citizens to evacuate, if at all possible.

As a further protective measure, prior to leaving on missions within 70 miles of the reactors, U.S. helicopter crews departing Naval Air Facility Atsugi were first given doses of potassium iodide to help protect their thyroid glands from possible exposure to radiation, Lapan said. The thyroid is particularly vulnerable to some kinds of radiation and the iodide reduces the risk of radiation illness.

Prior to Wednesday's missions, the only air crews that had been given potassium iodide were treated after being exposed to radiation, Lapan said, adding that when a sailor is given iodide is not an across-the-board policy.

"It was situational, based on the circumstances. They decide based on medical personnel who determine whether either afterward the tablets are something they can use as a precaution or if they can be used in a precautionary way," Lapan told reporters at the Pentagon.

Crews returned Wednesday with no sign of exposure, according to a spokesman for the U.S. Navy.

"None of the crews that came back today, including the crews given iodide in advance, showed any levels of contamination," said Lt. Anthony Falvo, a spokesman for the US 7th Fleet in Japan.

The only U.S. military assistance being provided to help Japanese authorities deal with the burning reactors is a pair of fire trucks from U.S. military bases in Japan that have been turned over to the Japanese. Japan has since asked for more pumps and hoses to go with the trucks, and Lapan said they are working to fulfill that request. No U.S. troops are part of the firefighting efforts.

The 7th Fleet now has 14 ships on station in the waters off the coast of Japan, including the USS Cowpens, which just joined the relief effort. A 15th ship, the USS Blue Ridge, is expected to arrive in a day or two.

It's unclear if the air crews who, prior to Wednesday, tested positive for radioactive contamination have been given a clean bill of health and clearance to fly missions again.

"It depends on the nature of the contamination, again if it's surface contamination, that can be taken care of with soap and water and disposing of your clothing, those types of things," Lapan said.

"That's different than ingesting (radioactive material), which is the reason they take the tablets."

Lapan said the Japanese government has not requested that the United States send military troops to help fight the reactor fires, but if a request was made, Washington would consider an exception to the exclusion zone.

"Remember, we're talking about the United States military -- we train and equip all of our people to operate in all kinds of environments. So we know how to measure, we know how to test, we know how to respond, we know how to take precautions," Lapan said.

Good catch. Yes, I would not be at all surprised to learn that the structural trough that the Mississippi River follows through the New Madrid system is geologically connected to the structural trough occupied by the St. Lawrence River. The two troughs are roughly in line with one another and form a nice western boundary to the Appalachian Mountains. Will have to do some digging later to see if this connection has already been made by geologists. Will let you know if I find anything.

Japan nuclear crisis: fire in fuel pools 'would raise radiation exposure'

A fire at the stores of spent atomic fuel in Japan's stricken nuclear reactors would dramatically raise the dangers of a radiation leak, scientists have warned.

Tokyo Electric Power (Tepco) confirmed a fire in Fukushima Daiichi's No 4 reactor on Tuesday, following an explosion that damaged the structure housing the massive concrete pools storing fuel rods used in the reactor. A further fire broke out at the No 3 reactor on Wednesday, where a fuel storage pool had overheated and may have let off radioactive steam.

Nuclear engineers warn there is more radioactive material stored in those pools than in the reactor core %u2013 and a fire would increase the chances of radiation spreading.

"If the spent fuel pool is on fire, the chances of radioactivity getting to the public are very much higher," said David Lochbaum, a nuclear engineer at the Union of Concerned Scientists.

He said the unit's reactor core was emptied out into the spent fuel pool last year following a shutdown. "There is much more material there because there is at least one reactor core plus what there was to start with, and it is in a building that has a big hole in the side of it," he said.

Scientists began raising concern about the possibilities of fire and radiation leak from the waste sites on Monday.

Robert Alvarez, a senior policy expert at the Institute of Policy Studies, told a conference call with reporters that satellite pictures of the Fukushima plant showed evidence of damage.

"There is clear evidence that the fuel cask cranes that haul spent fuels to and from the reactor to the pool both fell. They are gone," he said. "There appears to be copious amounts of steam pouring out of the area where the pool is located."

The damage confronts technicians with the tasks of cooling both the reactor and the fuel pools, where temperatures also began rising dangerously once the nuclear plants lost power.

"The spent fuel pool in unit 4 is boiling, and once that starts you can't stop it," said Jim Riccio, a nuclear expert at Greenpeace. "The threat is that if you boil off the water, the metal cladding on the fuel rods that is exposed to the air, and is volatile, will catch fire. That will propel the radiation even further."

A 2005 report by the National Academy of Sciences warned of just such a danger.

The study said the spent fuel pools put America at risk of a widespread radiation leak in the event of a terrorist attack. It went on to warn of a radiation leak travelling hundreds of miles causing up to 6,000 cancer deaths. The report urged immediate action to secure the pools.

But even that report - though dire - was not new. In the early 1990s, a number of nuclear engineers - including Lochbaum - warned about the dangerous situation of spent atomic fuel in US plants that were built along the same lines as those in Fukushima.

The engineers called for nuclear waste to be stored instead in dry casks at a distance from the reactors.

Their story made the cover of Time magazine. It did not, however, lead to any improvements in nuclear safety, Lochbaum noted. "It was a design mistake to put the spent fuel in the same building as the reactor," he said.

The proximity makes it much harder for technicians struggling to cool down the reactor and the spent fuel pool at the same time. "They are Siamese twins, you can't separate them," Lochbaum said.

Salon has this to say about that Oehmen "Don't worry; be happy" post stating there is no threat from fallout:

"Oehmen's essay has also been seized on by pro-nuclear partisans. A website called TheEnergyCollective.com -- which is run by Siemens AG, a major supplier for the nuclear industry -- republished Oehmen's blog post, and that version of the post alone was subsequently shared on social media sites 35,000 times. It was also posted on a pro-nuclear site called bravenewclimate.com"

Surprise! :-\

Yes, Oehmen works for MIT. But he's a finance guy, and has nothing beyond a layman's knowledges of nuclear energy. IOW, his blog post is yet another example--ala AGW--where a guy concerned with only money issues opens his mouth to speak of scientific things about which he knows next to nothing. The pro-pollution people may jump on the bandwagon, but that certainly lends no credibility...

(For what it's worth, I have no problem with the MIT NSE site. Just the debunked Oehmen article.)

Not that the model would of course be the end all as we know weather and events change over time - yet if that model were to come true - then nuclear radiation of harmful levels will reach Kamchatka and Baja.

I think one thing that worries me is Saturday's forecasted wind direction for Japan: ONSHORE. Due to a low pressure system moving in.

Unfortunately it sounds like if they can't get these issues under control in the next few days that it will reach a critical point where multiple full scale meltdowns are inevitable.

Just so happens that a couple of days lines up with Saturday.

Reactor unit #3 uses MOX fuel rods

#Danger of Losing Control of the Reactor Is Greater with MOX

Conventional LWRs are designed to decrease the reactivity when
the temperature rises. But when using Pu-239 as fuel, heating of
the core from an increase in reaction rate tends to increase the
reaction rate still further. This is called the positive
temperature coefficient of reactivity, meaning there is a danger
of losing control of the reactor by accelerated chain reaction of
fissioning.(10)


MOX spent fuel contains more fission products than uranium spent
fuel. The important factor in managing spent fuel is the heat
generation caused by the highly radioactive fission products.
Since spent MOX fuel contains much more fission products, the
heat generation from MOX spent fuel is twice as high as that of
spent uranium fuel after 10 years and three times as high after
100 years.(14)


#Accident Scenario When Burning MOX

Accidents involving overheating and meltdown are possible in any
nuclear reactors. In such accidents, not only would readily
volatile noble gases, like iodine and caesium be released
to the environment, but a small portion of the actinides,
including plutonium and neptunium would be released. As the
activity of the actinides is substantially higher in the case of
MOX, the consequences of such severe accidents become more
serious.


When MOX fuels are used, the probability of having such serious
accidents or trouble would increase due to the high content of
plutonium in the fuel. Even if an accident is not a serious one,
it could become serious since even a small portion of the
inventory of actinides released to the environment could cause
significant radiological consequences.

The impact on Major US companies are not currently measurable. The correct thing is to protect ones assests. Nothing wrong with that!!!!

As i mentioned earlier.....The Country of Japan owns a great deal of US Bonds that they will probably be cashing to rebuild their country. Hope you understand the position the US will be in when this occurs. The US dollar will be worth little while very high inflation takes over.....NOT A PRETTY PICTURE!
