GREAT TOHOKU EARTHQUAKE


If you have ever wondered what it would be like to be in a natural disaster such as the one in Japan these past few days, here is a good wkept ay to find out. The following is from a site kept up by a citizen and is called GREAT TOHOKU EARTHQUAKE. This is a minute by minute updating page. 

It makes for astonishing and educational reading and offers us much knowledge and what to expect of such a disaster in a country that is WELL PREPARED with the latest technology and trained people when such a disaster occurs. What is amazing in my eyes is how calm the people seem to be! I am sure this is not the case for all, but most just seem to take this, so far, in their stride.

Although I am on an upper level of a very solid building, I am beginning to question the wisdom of living at he Pacific Ocean shores.   

 

11TH MAR, 2011 BY MICHAEL IN JAPAN

 
I”ll be updating this post with ongoing announcements about the huge earthquake that is occurring in the Tohoku region of Japan. It has been labelled in Japanese the 東北地方太平洋沖地震 (Touhoku-chihou Taiheiyou-oki Jishin), the biggest earthquake ever to hit Japan. It struck at 2.46pm with a magnitude of 8.8 and was assigned the highest level 7 on the Japanese earthquake scale.

Aftershocks are still being reported in Tokyo and other areas even now (5:22pm). This earthquake reportedly had 32 times the energy of the
Great Kanto earthquake of 1923. It initially shook Tokyo and the northern cities Sendai and Iwate for minutes, producing huge tsunamis afterwards that reached 10m in height. The quake was also felt 100s of kilometres away in central Japan (by myself) and as far as Kyoto and Osaka, as reported by a friend on Twitter. There are also reports that it was felt in Beijing.

The quake struck at a depth of 10 km, about 125 km off the eastern coast. The area is 380 km northeast of Tokyo.

00.21 Explanation from an alleged Nuclear Reactor Operator from Reed College about nuclear reactor cooling systems.

In response to the question How serious is the threat to the Fukushima nuclear plant? on Reddit.

Disclaimer: IAaNRO (I Am a Nuclear Reactor Operator. I work part-time at my college’s research reactor)

Short Answer: It’s unlikely. It’s been shutdown, but the core is still producing heat. It’s not impossible for it to meltdown, but the main concern right now is that the steam pressure is rising in the cooling system, to the point where the system might rupture if nothing is done.

(Note: Originally I thought it was impossible for this reactor to meltdown at this point, but I’ve since been corrected. I’ve edited my answer slightly to reflect this)

Long answer:

Nuclear power reactors are of two main varieties: Pressurized Water Reactors, and Boiling Water Reactors. The plant in question is a Boiling Water Reactor (BWR). BWRs work by using the core’s thermal energy to boil the cooling water into steam, and then channeling the steam in order to turn a steam turbine. After it exits the turbine, the steam is cooled in a condenser, where it turns back to water, and then is sent back into the core. The condenser requires cool water to be actively pumped through it, to keep the pipes upon which the steam condenses from becoming too hot. The water/steam that runs through the core and the turbine is referred to as the “primary cooling system”, and the water running through the condenser is the “secondary cooling system.” 

The primary is assumed to be contaminated (that is, it is measurably radioactive), whereas the secondary system is not, since it is isolated from the primary.

As far as I can tell, the chain of events for this particular plant went something like this:

Shortly after the quake, the reactor successfully shut down in anticipation of the tsunami. This means that no more fission is occurring in the core. A meltdown a la Chernobyl is a result of uncontrollable fission. This will not be another Chernobyl. However, just because U-235 is no longer fissioning, doesn’t mean that the core isn’t producing heat. The fission fragments (those isotopes produced as a result of the U-235 fissioning) will continue to decay through alpha, beta, or gamma emission, until stable elements at the bottom of the decay chain are reached. The decay of these fission fragments and their decay products will cause the core to continue to produce heat for some time after shutdown.

Presumably due to the fact that every reactor near the east coast of Japan was being shutdown, off-site power for the secondary cooling system was unavailable, so the power plant had to rely on on-site backup power, but the on site power only lasted for 8 hours. After that, the secondary cooling system failed, which is what triggered the declaration of the Nuclear Emergency, and evacuation of those living within 3Km of the plant.

Since the core is continuing to produce heat, and consequently steam, the steam pressure inside the primary system is rising above normal levels. They are hesitant to bleed off steam into the containment dome, since the dome was probably damaged in the quake, but obviously bleeding off some steam is better than having the primary system rupture. Thankfully, most of the really nasty decay products have a relatively short half-life.

In particular, Nitrogen-16, which gives off pretty high energy betas when it decays, has a half-life of 7.2 seconds. Therefore, releasing the steam is undesirable, but not catastrophic, and probably not even particularly hazardous. 

The radioactive materials in the cloud will be longer-lived decay products of hydrogen and oxygen in, and as far as I’m aware none of those are particularly active. The cloud will be dilute itself after release, which will lower the intensity of the radiation field significantly. Therefore, the total radioactivity release will be many orders of magnitude lower than that of Chernobyl or Three Mile Island.

tl;dr: Right now, the fear isn’t meltdown, it’s mainly the steam pressure. The media are definitely playing up the meltdown angle, though.

Like I said, I’m a nuclear reactor operator ~ if you still have questions, please ask me.

21.46 Current death toll at over 1000 people.

20.45 Edano, Chief Cabinet Secretary, briefs the public on the situation at the Fukushima nuclear power plant, reactor 1. Beginning 14.00, valves were opened to begin releasing pressure building up in the nuclear reactor. Before this, radiation amounts were increasing. 

At 15.36 an explosion occurred as a result of the levels of water used for cooling the reactor decreasing. This gave rise to large amounts of radioactive steam, increasing pressure. This steam had a chemical reaction with the metal-coated pipes covering the nuclear rods, producing hydrogen. The hydrogen eventually combined with oxygen to cause the explosion, damaging the surrounding concrete and steel structure. 

The container and nuclear core reactor itself have not been damaged, so there will be no large radiation leaks. According to Edano, the density of radiation did not increase after the explosion. 

At 15.29, 1015μSv/h of radiation was detected (*edit* according to other sources this is equivalent to an annual dose for a human being). The explosion then took place at 15.36. 

At 15.40, 860μSv/h of radiation was detected, and at 18.58, 70.5μSv/h, showing that the level of radiation was decreasing. Currently, the radiation leakage to outside has not changed much. In order to prevent any further damage or leakage Tokyo Electric Power Company (TEPCO) are to fill the reactor with seawater (something rather unprecedented) to ensure it does not reach a critical state again. These measures have been put into place as of 20.20. Residents within the 10-20km radius are not in immediate danger, but the government wanted to err on the side of caution and extend the radius in case of any further complications. Asks all citizens to react calmly and beware of false information.

Regarding 1st and 2nd nuclear power plant in Fukushima, the first priority is the safety of people. New development has resulted in extending the evacuation order extended to 20km radius.

19.07 Safety advice collected via Twitter:
.
With the 1995 Kobe earthquake, the biggest aftershock occurred 3 hours after the initial quake. Prepare for those aftershocks even if it appears safe now.

Get some water ready and handy. Stock up some water in your bath tub or some other containers.

Get some emergency food ready.

Plug off unnecessary outlets.

Shut down gas and electricity, especially when you leave your house to evacuate or when the power is out. A fire is most likely to occur when electricity comes back.

Tokyo Electricity Power Company is asking to save electricity.

Keep windows open.

If you live near the ocean or a river, be aware of tsunami. 

 Here’s info on tsunami.

Don’t make phone calls unless absolutely necessary in order to ensure that those in need of making emergency calls can use the lines.

Using Skype, Twitter, Facebook, and e-mail is fine.

“Dial 171, leave a message with your home number. Anyone who knows ur home number can check your safety.” (via @beerintokyo)

Google Person Finder for this earthquake is available here.

Get warm clothes.

Be ready for potential power outage if it hasn’t happened to your area yet.

Check where the closest evacuation center from where you are. Parks, schools, and other public places are often used as an evacuation center. If you live in Tokyo, here’s a list of evacuation centers. It’s in Japanese, though.

If you are a woman, be careful for potential rapists who take advantage of this emergency situation and be with some other people. Don’t be alone.
